## Vertex Transform Patch Matrix Multiplication

Shaders

Logic and Math

Patch Editor

I want to transform the 3D position from the face tracker to clip space by multiplying it with the Vertex Transform Patch Model-View-Projection matrix. However, I am not getting the correct result. Is it possible to multiply a matrix with a vector via the patch editor?
