Perxenic-Acid/ssmt_node_thumbnails

A shader node preview tool for Blender 5.2, built with Vibe Coding.

Key features:

  • Free & performant – good performance without the cost.

  • Smart caching – thumbnails are cached per material tree / sub‑tree; moving or rearranging nodes won’t trigger re‑renders.

  • Stable saving – queue pauses before saving .blend; temporary data is cleared safely.

  • Render‑aware – thumbnail queue auto‑pauses during final stills or animation renders, and resumes afterwards.

  • Debounced updates – waits 0.45s after node tree changes before processing.

  • Priority queue – renders selected nodes first, then nodes near the viewport center.

  • Duty cycle control – choose 25%/50%/100% batch duty cycle to balance responsiveness.

  • Group path awareness – node group thumbnails inherit textures, values, and upstream connections from their parent material, with separate caches per usage context.

  • Fallback mode – if Blender can’t provide reliable path info, falls back to isolated group preview.

Latest fixes (0.4.6):

  • Fixed _resolve_node_group error for sub‑node trees.

  • Added common UV semantic aliases (UVMap, TEXCOORD.xy, etc.) for preview spheres/planes.

  • Reuses Material Output and Emission nodes across a batch.

  • Redraws only the relevant node editor after each thumbnail, not all editors.

  • Handles read‑only ShaderNodeTree.name in Blender 5.2.

A stable, lightweight preview solution for Blender 5.2 shader workflow.

Actually, it has no relation to SSMT itself.
