I made Kiln a while back to handle the "Blender procedural materials don't survive GLB export" problem. Just pushed v0.3 with a feature that should be useful if you bake assets for game engines.

**Split Bake** lets you produce multiple texture sets from a single collection in one click. Five modes:

\- **By Material**: one set per material name.

\- **By Material Index**: one set per slot (useful for Geometry Nodes setups).

\- **By Object**: one set per object, good for kit assets where each piece has its own atlas.

\- **By Mesh Island**: you pick how many texture sets to spread the islands across. Kiln groups them by size to balance the atlas.

\- **By UDIM**: one set per UDIM tile. All tiles get remapped to tile 1001 in the output, so Godot just sees standard textures.

The \_Kiln collection contains separate meshes per group, each with its own material and UVs. GLB export is clean.

Also added: an **Image Filter** setting (Closest for pixel-art / stylized) and a **Bake Preview** that shows the texture count before baking.

Free for existing buyers.

Happy to answer questions.
