Texture Layout Dilate

Overview

Expands the edges of texture UV islands into the surrounding padding through dilation. Transparent or unrelated colors immediately outside a UV boundary can bleed into the edge during texture sampling, creating black fringes or seams. This node performs the standard game-texture preprocessing that prevents those artifacts.

Usage tips

• Its usual position is immediately before application or export: finished texture
  • the primitive's texture_layout output → Dilate → model_set_material.
• It expands only into the gutter without crossing UV islands, so neighboring islands remain clean.
• If strange colored lines appear along model edges, first check whether this step was omitted.
