Model Texel Density Check

Overview

Checks a model's texel density—the number of texture pixels per world unit. With pixel-art textures, inconsistent density is immediately visible as pixels that appear different sizes on different parts, so this node detects that break in visual consistency.

Usage tips

• Target = BoundMaterial (the default) compares every part region against the texel_density of its bound PBR material. Only unbound regions fall back to the Texture Layout density. Choose Explicit to check everything against one value.
• Measurement uses each part's final world transform, including its parent hierarchy, rather than raw mesh coordinates. Two differently scaled parts sharing one mesh are therefore measured separately.
• Warning examples identify the exact Part ID:region#triangle.
• Use it as a quality check before export. If a region falls outside the allowed range, adjust its UVs (including trim-sheet assignment) or the texture resolution.
• It is especially useful for models assembled from multiple parts. Automatic UVs on a single primitive rarely cause problems.
• This node performs inspection only and does not modify the model.
