Model Trim Sheet Apply

Overview

Remaps named model regions to a trim sheet—rectangles on one shared texture. It implements the common game-3D technique of sharing one texture among several models and assigning strip-shaped rectangles to individual parts, without editing vertices.

Usage tips

• Region Rectangles uses a table editor with suggestions from the connected Texture Layout. Edit each region's inner X/Y/W/H rectangle there. Out-of-bounds padding and overlapping padded rectangles are reported immediately; invalid JSON opens a multiline recovery field.
• The output Texture Layout preserves the input texel_density; applying a trim sheet never silently resets the target to 16.
• Use it when several models should share one texture. Combine the walls, roofs, and trim for a building set on one sheet, then map each model region to its matching rectangle.
• After assignment, use model_texel_density_check to look for density inconsistencies.
• For a self-contained single model, automatic UVs plus model_set_material are usually sufficient.
