Feature ToDo

Ideas for features to add.

Bigger Features

See the Roadmap.

Smaller Features

• Ambient occlusion color node
  • For specifying custom AO normal and using it as shader color
• Gabor noise node
  • Can generate many interesting patterns, might need good UI for parameters
• Per object multiplier for motion blur shutter time
• OpenColorIO integration
• Use render visibility when selecting render layer preview in viewport
  • Needs depsgraph fixes
• Add back worley weights to voronoi node.
• Access to object color and other object properties from nodes (support RNA paths?).
• Option to include environment lighting in shadow pass.
• UV project modifier special mapping for UV maps to avoid distortion.
• Vertex color RGB+Alpha support (for dynamic paint, see T36832)
• Support video texture auto-refresh for viewport's Texture and Material shadings, see T40295
• Motion blur doesn't work together with autosplit T42315
• Hair does not get proper color when emitted from vertices T42706
• Using Triangles for Hair loosing intercept information T43625
• Depth pass could be improved for volume/smoke T43836
• Multiple steps for object motion blur T44005
• Handling multiple image datablocks pointing to the same image on the disk T45124
• Make duplicator visibility policy matching Blender Internal T43590
• Look into improved UV projection from view support T46014
• Make Hair settings per particle system instead of per scene.
• Voronoi texture is biased towards coordinates T50658
• Clipping doesn't work in GLSL viewport T53468

UI

• Select individual GPUs for rendering in user preferences.
• Node link menu in properties editor has become too big, needs to get submenus
• Properties editor UI should be improved, perhaps:
  • Add outliner like alternating lines
  • Some better indication of hierarchy that doesn't take up much horizontal space
• Better auto position when adding nodes (with multiple inputs nodes overlap)
• Auto sync BSDF color and viewport color
  • Needs some algorithm to deal with mix shader hierarchies, to find the good diffuse node
• Decouple lamp size for hemi/sun lamp and point/spot/area, the units for the former are wrong
• Show watts, watts/m^2 units in the UI
• Hide color component for node sockets in the UI

Performance

• Indirect light influence control
• SIMD for triangle intersection
• Spherical triangle light sampling for mesh lights
• Enable selective features compilation for CUDA and shader/baking kernels of OpenCL.

Workflow

• Pause rendering when 3d view gets hidden
• Progressive Animation Rendering (details)
• Render pause button
• Keep scene in memory and sync between F12 render (avoid image/mesh/.. reloading)
• Allow user-defined attribute requests associated with OSL code (T39415)
• Better support of ray visibility of volumes (T48512)
