Coloermap and Vertex Uvs do not work together?

[sanostol]

Hi,

I have a object with vertex uvs (obj import). now I want to use a vopsop to assign a color to each point according a image and the uvdata, but the result looks more than strange.

I tried a simple setup with pointuvs and it works, the vertex also fails on the grid, but I can assing the color using the tex() expression in a pointsop, though. so My question is why does the vopsop fail, when the expression does not?

I attache a example scene

thanks a lot

In your example, switching to point Group Type in the uvproject2 node seems to work, no? Is this what you want?

well, but switching to point mode in a loaded geometry with uv coordinates is not possible

another thing is that the pattern changes everytime You load the scene

but point uvs can not be broken up, so I can not get the same texuring as with vertex data

VEX operates only on points.

damn, but logical.
