Cinema 4D MCP

Source of Truth

This skill targets Vlad's fork of Cinema 4D MCP: vladmdgolam/cinema4d-mcp.

Relevant fork additions:

• inspect_redshift_materials - read-only Redshift inspector for assignments, preview-derived colors, readable description/container fields, and best-effort graph probing. Note: this tool may skip RS materials as not_redshift_like (type 5703) — use execute_python_script with the maxon API for full RS node graph extraction instead (see Redshift Material Extraction section).
• Duplicate-safe material targeting - the inspector accepts material_index and returns stable scene indices plus duplicate-name hints when names collide.
• Redshift GraphView fallback - when node-space access fails but import redshift works, the inspector falls back to redshift.GetRSMaterialNodeMaster(...) and reports GraphView nodes plus resolved connections.
• The loaded C4D plugin may lag behind the repo copy. After plugin edits, restart Cinema 4D before trusting new tool behavior.

Tool Selection

Use structured MCP tools (get_scene_info, list_objects, add_primitive, etc.) for simple operations.

Use execute_python_script as the primary path for non-trivial extraction. It avoids wrapper/schema mismatches, gives full c4d + maxon API access, and allows proper frame stepping control. This is especially important for Redshift material extraction — the maxon node-space API gives full access to RS node graphs, which other tools may miss.

Use inspect_redshift_materials as a quick overview of material assignments and preview colors, but be aware it may skip RS materials as not_redshift_like if they use type 5703 wrappers. For full RS node graph data, use execute_python_script with the maxon API pattern documented in the Redshift section.
