hi,

i have two identical meshes with different uv (vertex attribute)
i can use the blendshape on the uv attribute to blend between the uvs...
i now want to paint the blending areas. for that i used the attribute paint sop, but when i add @mask to the blend value slider in the blenshape sop, i get an error that the @mask variable does not exists.

how can i use the attribute paint on such a scenario? does somebody has a hint?
