Limitations

Current limitations:

• Some Forge features still fall back to the interpreter when they do not fit the current VM/JIT subset
• subsurface is not yet rendered as true subsurface transport
• the renderer still contains some backend-specific recursion logic
• the language is still evolving and should not be treated as stable yet

Near-term priorities:

• stabilize the Forge material runtime contract
• improve renderer correctness around custom BSDFs
• document the language and material system as they evolve
• widen VM/JIT coverage for more Forge shading and procedural code
