Radeon™ ProRender is a powerful physically-based rendering engine that enables creative professionals to produce stunningly photorealistic images. Built on highly efficient, high-performance Radeon™ Rays technology, Radeon ProRender's complete, scalable ray tracing engine uses open industry standards to harness GPU and CPU performance for swift, impressive results.

This Radeon ProRender plug-in for Blender™ ​is a feature rich solution which enables the user to render high quality images of their models. With this tool, users can render and then perform a host of post image processes. 

The latest Radeon ProRender for Blender plug-in can be downloaded from the following links: 

Radeon ProRender for Blender v1.7 Highlights

  • Add checkbox to use Metal native raytracing API to render settings.
  • Updated Uber shaders:
    • Diffuse backscattering option, allows simple backlighting for thing objects like tree leaves or semi-translucent film.
    • Clearcoat thickness and transmission color.  Allows simulating effects like a laquer on a surface, allowing the artist to specify how thick the coating is, and if the coating has a color to the substrate, for example a yellowish tint to a varnish on furniture.
    • Refraction absorption, for glass and liquid objects that scatter light, for example deep water or glass with particles in it.
    • Per lobe normals.  Artists can specify a normal map for each lobe, for example in car paint, a different normal map can be used for just the clearcoat to simulate micro scratches from waxing the surface, while the underlying material has a smoother normal map.
    • Refractions (Glass) Now default to not allow caustics, this will lead to faster, less noisy images as caustics are not computed unless necessary.  For materials that the user does want caustics for, simply enable the checkbox in the refraction section of Uber.
  •  Reorganization of render settings, allowing clearer user control of render settings.
    • Different device configurations for viewport and final renders. 
    • Ability to set viewport resolution and disable effects in viewport for faster viewport renders.
    • Set number of CPU threads for CPU renders (additionally remove a limitation of 32 threads to support Threadripper systems)
    • Control ray depth separately for diffuse, shadow, reflections and refraction
  • An ambient occlusion node is added for various uses.  This is helpful for simulating "dirt" on a material or any time a material is wished to be blended or changed based in concave sections of geometry.  Set this to use the front side to blend on the crevices, or back for pointed parts.
  • Moving cameras now blur the entire image
  • An ambient occlusion node is added for various uses.  This is helpful for simulating "dirt" on a material or any time a material is wished to be blended or changed based in concave sections of geometry.  Set this to use the front side to blend on the crevices, or back for pointed parts.
  • Texture map wrapping option allow different options for wrapping textures, if they should repeat outside the 0-1 UV range or clamp, or "smear" the texture
  • Normal map nodes have a setting to flip in U and V directions independently
  • Material preview render down sample textures for faster loading and switching between materials
  • Node socket min/max and default values have been edited for ease of use, particularly weight and roughness values
  • Separate Shadow, refraction and glossy refraction ray depths are added in the render settings
  • Viewport renders now use Blender native gamma and tone mapping, including the Filmic tone mapping settings.

Fixed Issues

  • The clamp irradiance property now defaults to 1 as in previous releases.
  • Fixed an issue with number of samples per view update. Set this value higher for less view updates but faster renders.
  • A Reflection Visibility property has been added to objects.
  • Improvements to multi material support have been made.
  • A number of Uber3 default values have changed from 0 to 1: ReflectionWeight, RefractionWeight, CoatingWeight, EmissiveWeight, SubsurfaceWeight, Transparency.
  • Defaults for the CPU render thread limits are now set correctly.
  • The time render limit now works correctly.
  • Added a FresnelBlend node which allows mixing between two colors with a fresnel curve.
  • Animation drivers/keyframes will now update the "RPR Value" output for shaders.
  • A crash when switching to the node editor has been addressed whilst viewport rendering.
  • SSS was not working correctly unless manually enabling backscattering or refraction.
  • Render with multiple layers has been improved.
  • An issue causing black polygons with quad geometry and NVidia GPUs was fixed
  • A crash with bad smoke domain data is now caught
  • Instanced objects (particles or Blender dupli objects) are exported from Blender to rpr faster.  Many instances sharing a material will export faster now as they export the material and mesh once rather than multiple times.
  • Edge artifacts on objects with transparent background setting turned on are now fixed.
  • A particular crash when detaching a material with textures is fixed
  • Image textures are now read from disk faster.  NOTE: Performance of exporting scenes with textures on disk as opposed to textures "packed" into the blender file is much better.
  • Adaptive subdivision uses less memory
  • Float Tiff textures should work properly now
  • Reflection of light sources is fixed.

Known Issues

  • Smoke domain objects must have a transparent material attached to render the smoke inside.
  • Intel® integrated graphics are disabled on macOS, however CPU mode is available.
  • Displacements with Uber materials on macOS have been observed to cause instability in rare cases.
  • Denoiser does not work with CPU rendering and is disabled.
