Sycles addon 2.3

What's new

• Compiled with Cycles render engine version 4.5 (last commit at 2 April 2025)
• Bring back OSL-support. In particular implement #15. It allows to render OSL-shaders on OptiX gpu.
• Add new shader nodes:
  • Metallic BSDF
    
  • Set Normal. It allows to define normals, calculated in the shader
• Add parameter for phase function in Scatter Volume node
  
• Add Diffuse Roughness for Principled BSDF node
  
• Additional noise types for Noise Texture node
  
• Improved subdivide. In particular now the Cycles render subdivided object with activated motion deform
  
• Implement #36. It allows to use different texture images at different render frames
• Initial implementation of #3.
  • Render NURBS surfaces. By default these surfaces are not rendered. To make it visible, it's required to add CyclesSurface custom property. This property contains two parameters U/V Density. Surface is rendered as a set of square parametric patches. So, these parameters control the polygon density of the surface.
    
  • Render curves. To render it, add the property CyclesCurve to the curve. Each curve rendered as strand. Parameter Density define the number of points in the curve, Size - the radius. Softimage assume that curves are not renderable. It's impossible to define the curve material. Material option box allows to select material from the scene for the curve. The rendering of the curve is not stable, in some unexpected cases it crashed.
    
• Implement #12. It's tile rendering mode.

Bug fixes

• #32. In particular fix shadow catcher.
• #33. Properly find custom property by using type instead of the name.
• #31. Now gpu-s are properly detected for the rendering.

Known issues

• Hybrid displacement mode is broken in the Cycles engine (https://projects.blender.org/blender/cycles/issues/30). For now this mode is disabled from the UI. Only Bump and True Displacement are allowed.
