Hello vvvvorum

I want to get position vertex my 3D model.

For Examlpe i use:
BOX->Topology->GetVertexData->ReadBack float 3 but my results it is only Zero.

What is the best way to get Vertex position my 3D model?

it looks right, is your ReadBack node a 3d Buffer type ?

yeah works fine afaik. Sometimes shaders won’t always evaluate if it’s not connected downstream, so you can try connecting it’s geometry output if you don’t have luck otherwise
