Feature Request: Allow OpenSubdiv to pass Edge Crease/Weight data up the modifier stack (like MeshSmooth)
[Description/본문]
Currently, the OpenSubdiv modifier in 3ds Max does not pass Edge Crease or Weight data to the upper layers of the modifier stack. For example, if the stack is [Editable Poly -> OpenSubdiv -> Chamfer], the top Chamfer modifier cannot read the original crease data from the Editable Poly.
Why this is a problem:
Broken Non-Destructive Workflow: To preserve edge data for a non-destructive Chamfer workflow, we are forced to use the legacy MeshSmooth modifier. However, MeshSmooth is CPU-dependent and causes severe viewport lag on complex meshes compared to OpenSubdiv.
Competitor Advantage: Blender uses the exact same Pixar OpenSubdiv technology but successfully passes this data to subsequent modifiers. This structural limitation in 3ds Max is one of the key reasons hard-surface modelers are migrating to Blender.
Request:
Please update the OpenSubdiv modifier architecture in 3ds Max so it preserves and passes underlying sub-object data (Crease, Weight, Smoothing Groups) up the stack, exactly like MeshSmooth does. We need the GPU performance of OpenSubdiv without sacrificing the non-destructive modifier stack data flow.
