Radeon ProRender for Blender v1.6 Release Notes


Last Updated: May 9, 2018

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/add-in can be downloaded from the following links:

Radeon ProRender for Blender v1.6 Highlights

    • Support for macOS High Sierra 10.13.3+ using Metal® 2. eGPU devices requires macOS® High Sierra 10.13.4.
    • PBR and Uber shader get more intuitive subsurface scattering parameters, simply set a scattering color and length for how far internal reflection should go in a surface.
    • PBR Shader Updates:
      • PBR shader is updated to easily do glass, organic, metal, plastic or diffuse materials.
      • Emissive weight is added to mix emissivity with the surface.
      • Cycles "Principled Shader" is converted to PBR nodes when using material conversion.
    • Uber Shader Updates:
      • Uber is now the default shader when adding a material.
    • Many new AOV's, useful for compositing or diagnostics are added to render passes.
      • These now appear automatically in Blender's compositor as well.
    • An additional control for setting camera exposure to allow adding more motion blur is added.
    • Image texture nodes now have a setting for "Texture Gamma".  Set this to "sRGB" for color maps (such as PBR albedo textures).  All other texture usually should stay as the default setting, "Linear".  This will fix washed out looking color textures.
    • Physically based lighting controls greatly improve lighting setups.
      • Additional area light shapes include:  Rectangle, Disk, Cylinder, and Spheres.
      • Light color can be set by temperature, color, texture, or all three.
      • Intensity can be set additionally with physical units.
    • Color Ramp Shaders are now available.
    • Max diffuse/reflection depth controls are added.  This allows performance optimization for scenes that don't need much GI.
    • Adaptive Subdivision - in addition to setting a uniform subdivision level, this control allows setting subdivision level that "adapts" based on how large an object is to the camera.  Closer objects will refine more, while far away object will not over-subdivide.  This setting is in pixel units, so "1" will subdivide to approximately one pixel in size, set it to higher for coarser subdivision or lower for finer.
    • Blender smoke is rendered as a volume object.
    • Area lights can be made invisible to reflections.

Fixed Issues

    • PBR and Uber shaders using the "metalness" parameter to set reflectivity now work correctly for dielectric (non-metal) materials.
    • Various issues with denoiser are fixed – particularly when combining with shadow catchers.
    • Shadow catchers update while interactive rendering.
    • Ray episilon setting is added.  Change this value to fix black spot artifacts with glass or other reflections.
    • Blender's UI panels (such as physics settings) are unhidden.
    • Bump Mapping nodes with no input are now ignored as opposed to rendering an error.
    • An error with render passes in Ubuntu® is fixed.
    • Denoiser can be disabled for interactive rendering.
    • Emissive nodes work double sided.  Additionally, emissive shaders converted from cycles now do not need to be flipped 180 degrees.
    • World background color and IBL settings are converted from cycles.
    • AOVs work correctly while using shadow catchers.
    • Support for AMD Radeon™ Pro 580 and AMD Radeon™ Pro 560 added.
    • Various NVIDIA® OpenCL™ fixes.
    • Fixed crash with IPR rendering with shadow catcher objects.
    • Blender 2.79 compositor was not adding the RGB input for compositing
    • Render image convergence is much better with IBL Maps applied.

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.
