Features & Production Pipeline Workflows

Writing OSL Shaders (Codes & Nodes)

Dual-mode shader authoring: visual node-graph composition alongside direct C++ style code editing for instant interactive parameter tuning.

Scene Assembly for LookDev

Build inspection stages for look development (currently loading .obj geometry, architected for future OpenUSD .usd stage compositions).

Scene Graph by OSL Shaders

Construct procedural scene graphs driven by OSL shaders, compiled and ready for one-click rendering in Arnold, Karma, RenderMan, and Cycles.

Multi-DCC Pipeline Interchange

Direct scene hand-off and shading network interchange across Maya, Houdini, Blender, and Katana without translation discrepancies.

OSL Post-Processing Pipeline

Real-time post-effects rendered via OSL passes: depth of field (DOF), optical lens flare, pantone color matching, and stylized toon contours.
