Vertex Weights to UV Map

Convert vertex weights to UV coordinates, for use in shaders. The Tissue addon includes this function for the reaction–diffusion weights.

Instructions

• Select the vertex group you wish to convert to UV map.
• Select the object in Object mode, and click on Object > Vertex Weights to UV > Active Vertex Group(or All Vertex Groups).
• This should create a new UV map with the same name as the selected vertex group.
• The weights in the vertex group are now available in the Shader editor through the "UV Map" node.
