Switching to Radeon ProRender
Launch Blender. In the Info header, select Radeon ProRender in the renderer dropdown. If you don’t see it
in the dropdown, check Add-ons, and activate it there.

If Radeon ProRender is activated, the content in the Render Panel/Render Setup should change to
Radeon ProRender -specific settings.

Radeon ProRender plug-in for Blender User Guide

SCENE SETTINGS

Scene Settings
Once you’ve changed your renderer to Radeon ProRender, you will have access to the following render
settings.

Radeon ProRender plug-in for Blender User Guide

SCENE SETTINGS

Render
Under Render, the output can be a still image, or an animation without or without audio.
Note: Radeon ProRender follows the Blender standard, meaning renders will be are displayed in
the UV/Image Editor, and the display options are the same as in Blender native, meaning that
clicking the lock next to the dropdown will lock the interface at rendertime to give more memory
to the renderer.

The display dropdown will let you select between:
•

Keep UI – The image is rendered to the UV/Image Editor, but the UI remains the same. You will need to
open the UV/Image Editor manually to see the render result.

•

Image Editor – A new floating window opens up, displaying the render.

•

New Window - One of the existing editors is replaced with the UV/Image Editor, showing the render.

•

Full Screen - The UV/Image Editor replaces the UI, showing the render.

Dimensions
Set the sizing and resolution for your render output. You can choose between custom settings and
presets from the dropdown. This is also where you define your frames and framerate for animation.

Radeon ProRender plug-in for Blender User Guide

SCENE SETTINGS

Output
Lets you define where and how to save your render output.

Render Resources
Render Resources lets you define your rendering device(s). First select your rendering mode – CPU or
GPU. Then select your devices in the dropdown. You can use multiple GPUs or CPUs.
If your GPU(s) are incompatible, Radeon ProRender will usually default to CPU-rendering. If it doesn’t,
you will need to set it manually.

Tone Mapping
Tone Mapping allows you to change the brightness and/or contrast of your image or animation based on
real life camera settings or algorithms. Radeon ProRender provides three settings for this.

Simple
This is a simple exposure tweak and contrast option. You can brighten or darken the image by controlling
the exposure, or having brighter or darker contrast.
Radeon ProRender plug-in for Blender User Guide

SCENE SETTINGS

Linear
This is based on real-life camera settings. ISO is film speed – the higher the value, the more light is let
into the image. F-Stop is aperture width, and follows regular camera settings – the smaller the number,
the wider the aperture, and the more light will be transmitted to the film. Shutter Speed is how long the
shutter stays open to let in light, also known as exposure.
Non linear
This is also known as Reinhard which is aimed at adapting the high dynamic range of real world lighting to
your screen.
Note: It does this by letting you set values for Burn, Post Scale and Pre Scale Pre Scale and Post
Scale work together, this means that if you tweak one, you’ll probably have to tweak the others.
Pre Scale controls the brightness of darker areas (i.e. shadows). Post Scale controls the final brightness
of the image and Burn is used to tweak the brightness of highlights in your image based on its darker
areas.

White Balance
White Balance follows the basic settings of a digital camera – lets you set the color temperature of the
light in the image.
Note: A color temperature is set in Kelvin – a lower value will turn your light a cold blue and a
higher value will give it a warmer tone. The default is 6500 which will give you nice white light and
highlights.

Note: Whenever a white box is apparent, you can set a specific color and you can choose
between several colour spaces.
Colour Space: Rec. 2020, DCI P3, Adobe RGB, Srgb
Colour Picker
Specify the colour using the RGB (Red, Green, Blue), HSV (Hue, Saturation, Value/Brightness) or Hex
colour space.
Note: Whenever you see the white rectangle, you are able to choose a color using this color
palette.

Radeon ProRender plug-in for Blender User Guide

SCENE SETTINGS

Gamma Correction
This will make the scene look brighter or more faded out. You can choose to set this in the render
window, or in the viewport only.
Note: Radeon ProRender for Blender follows the Gamma 2.2 standard, meaning it will look
correct out of the box. If you decide to tweak your Gamma settings, remember you may need to
tweak your tone mapping as well.

Depth of Field
This will let you focus on an object in the scene and blur the foreground or background surrounding it via
the camera settings.
Once you’ve checked the checkbox to activate it, Radeon ProRender will show a Focus dropdown listing
scene items the camera can focus on, as well as giving you the option to pick a camera.
•

F-stop – In this context, the F-stop controls the blur in the image. If you stop down to low settings, you will
get more blur in the areas that don’t have focus.

•

Distance – If you chose to just use the camera, the Distance parameter defines which area in your 3D
space will be the focus based on the distance you define here – the focused area defined by distance will be
clear, the rest blurry.

•

Blades – Blades define the amount of bokeh in your image, if any. Low settings will give you hexagons, high
settings will give you circles.

Note: This changes the DOF from the active camera view. Press Num Pad 0 to shift to the active
camera view.

Radeon ProRender plug-in for Blender User Guide

SCENE SETTINGS

Motion Blur
As with other cameras, Radeon ProRender’s Motion Blur will make object appear as if it’s in motion, in
stills as well as animations. You can select whether to use Geometry – an object in your scene – to blur, or
the image or frames themselves.
•

Exposure - longer exposure means more motion blur

•

Scale – the scale of the motion blur

Sampling
Limit the rendering samples by time or the number of iterations.

Anti-Aliasing
Like with Blender’s native Anti-Aliasing, Radeon ProRender’s anti-aliasing smooths the pixels in an
image, by oversampling single pixels as if they were five pixels or more, and calculating the average. This
will in many cases get rid of the harsh edges you can see in some renders with no AA set. There are
several algorithms to calculate this, and Radeon ProRender has added Lanczos and Blackman/Harris as
well as some of the standard ones.
A high number of samples gives you a better render at the cost of render time. The width changes the
width of the filter and the grid refers to grid pattern for the AA grid – the smaller the grid the higher the
render time.

FILTERS

DESCRIPTION

TRIANGLE

equivalent to Blender’s Tent – for sharp results

MITCHELL

default filter, good for all-round rendering on images with no major high
contrasts

LANCZOS

a second good all-round filter

GAUSSIAN

provides blurry Anti-Aliasing

BOX

the lowest quality Anti-Aliasing filter

BLACKMAN HARRIS

complements the Box and Gaussian filters, and is especially effective for
Wireframe renders, as it makes edges look smoother

Material Preview Settings

This will preview the material’s Radeon ProRender thumbnails. Useful for mixing different shaders and
previewing the color in the NodeEditor. Click on the object in the viewport. Apply a material by selecting
the Material tab

and clicking New.The material preview iterations will be evident in this section.

Radeon ProRender plug-in for Blender User Guide

SCENE SETTINGS

In the node editor, there is also a material preview option, such as using the RPR Shader Blend. Check
the RPR Thumbnails checkbox and choose to have a large preview or a small one.

Mode/Quality

This is used for the final shot, or for the viewport and they are set independently.

Radeon ProRender plug-in for Blender User Guide

SCENE SETTINGS

Render Mode
Render Mode changes the look of the 3D model in the viewport.

MODE

DESCRIPTION

standard pass to do anything from showing off your models without
textures to using it as an overlay for contact shadows, which GI doesn’t
always catch

Radeon ProRender plug-in for Blender User Guide

SCENE SETTINGS

Max Ray Depth
Max Ray Depth changes the number of times that a ray bounces off a surface to capture reflections.
Notice the image quality of the model when using number of ray bounces of 1 (left) and of 5 (middle) and
of 20 (right). The transparency and colour of the object is improved with more ray bounces. In the left
most photo, the object is black, since the surrounding light is unable to reach the inner surfaces due to a
low ray bounce setting.
Tip: When using glass or other translucent appearances, use a high number of Ray Bounces to
fully capture all reflections (generally, a good number is 6 unless there are complex, translucent
parts).
New in v1.6: Max ray depth can also be controlled for diffuse and specular ray depths separately.
Thus for scenes with many nested transparent objects, set a high specular ray depth. Diffuse
ray depth is usually fine to leave at 1 or two.
Improved image quality comes at a cost to other factors. The right render took more time than the left
render to produce qualitatively, the same image quality.

Radeon ProRender plug-in for Blender User Guide

SCENE SETTINGS

Stamp Settings
This will create stamp on final rendered image showing details of hardware and Blender scene
information.

This is the stamp on the rendered image.

Developer Diagnostics
Should you be so unfortunate as to experience crashes, please turn on the Trace Dump. The Trace Dump
will not store any kind of personal information, it will simply enable the developers to pinpoint how and
why the crash occurred based on the data present in the scene – and hence the trace file.

RENDER LAYERS SETTINGS

Render Layers Settings
Render Layers allow you to render your scene, or items in your scene in layers. This is handy if you are
compositing or doing postwork.

Layers
The RPR Layers settings follow the Blender standard setup, where you add layers containing scene
elements and their render settings to the layer list.
Only visible layers will be rendered.
•

Scene shows the scene layers currently visible.

•

Layer shows the scene layers associated with Radeon ProRender, and they will render the objects and
materials associated with Radeon ProRender.

RENDER LAYERS SETTINGS

Denoiser
New in v1.5+: Enable the checkbox, select the filter type and how fine or wide you want to filter
the image with the settings. Using a finer filter will preserve more image detail, while a wider
filter will give less noise. This should allow you to get noise from your render while keeping
samples and render times low.

The image on the right has denoiser turned on.

Radeon ProRender plug-in for Blender User Guide

OBJECT SETTINGS

World Settings
Environment IBLs and Sun & Sky
IBLS
You can just use the native, single color setup for completely neutral GI lighting or you can pick the color
via RGB, HSV, or Hex.

You control the intensity of the lighting via the Intensity slider, or you can load an HDR or EXR to
illuminate your scene without showing the IBL itself. If you opt to use the latter, the intensity will also be
controlled via the intensity slider.
If you set override background, you can set the background color or IBL map independently of the world
lighting. the Transparent Background option allows you to give the background a 0 alpha while still
showing the color/map.
Cool fact: If you render a scene using an HDR with an HDR, you get a stacked HDR you can reuse for other scenes – just mind your copyright.

Radeon ProRender plug-in for Blender User Guide

OBJECT SETTINGS

Your IBL will determine how the lighting in your render is reflected or refracted onto the surfaces of the
model. You can use alternate images or colours to change this. One way to fake soft reflections, for
example, is to use a blurred copy of your lighting IBL to generate this without having to tweak your
settings too much.
Sun & Sky
Radeon ProRender can simulate a sun & sky background. You can even set the environment depending
on a location in the world by clicking the Date, Time and Location toggle.

Radeon ProRender plug-in for Blender User Guide

OBJECT SETTINGS

Object Settings
Radeon ProRender has a few options under Object:

Radeon ProRender plug-in for Blender User Guide

OBJECT SETTINGS

Settings

Shadow Catcher – Follows the general 3D workflow of setting up a plane or object capable of receiving
shadows and becoming transparent, so it can be seamlessly incorporated into i.e a backplate or an IBL.
New in v1.4+: Objects can be marked as shadow catchers for compositing rendered shadows to
a background.

Casts Shadows – enables shadows

Radeon ProRender plug-in for Blender User Guide

OBJECT SETTINGS

Portal Light - Placed in windows or near the main light sources in your scene, a Portal Light is
typically used to boost incoming GI/Environment light (from windows) in interior scenes. It does this
to speed up rendering by sampling and boosting light more efficiently, thereby also reducing the
noise in the render after less passes.
Camera Visibility: Make objects visible/invisible to main render. You could turn this off to make an
object only show up in reflections for example.
Subdivisons: This subdivides your geometry at render time to give you finer and smoother mesh.
There are two different modes:
•

Level Mode - subdivides your geometry N times always.

•

Adaptive Mode - Use this to adaptively subdivide your geometry. The setting is how fine geometry
should be divided in pixel size. Thus, setting it to 1.0 will subdivide geometry to 1 pixel in size based on
how close to the camera the object is. The advantage is and item that is far away from the camera will
not be overly subdivided as it might with Level mode.

Motion Blur
Set the scale of the motion blur. This will need to be enabled under the Scene Settings for you to adjust.

RENDER IMAGE EFFECTS

Working with Materials
The Radeon ProRender Materials Panel will let you define options for a single, or multiple shaders, and
follows the standard Blender workflow.
Access the Material by clicking the Material icon in the Object’s properties editor. Add a new material by
clicking the + sign next to the Active Material box, and the new material will display, ready for editing, as
