Decal Project

The Decal Project Tool is in the Active Node Properties in GMAT panel of the 3Dview.

It appears if a Image Texture Node is active in the GhostTree. This node points to the decal texture prejected.

What's it for ?

Interactive creation of a dedicated UV attribute for mapping decals. The projected UVs are stored in a generic FLOAT2 attribute (vertex domain), read back by a UV Attr node.

Tip

Because the projected UVs are stored as a generic attribute (not a UV Map), they do not count against Blender's limit of 8 UV Maps — you can project as many decals as you need.

result: a UV Attr node is created and connected to the Image Node

Procedure

Note

Object needs a minimum of definition to have a good expression of the color attribute
