Hi, I am trying to transform the camera ray to tangent space. I am using a kma_rayimport node (Vector3, ray:direction)and a mtlxtransformvector to transform the vector. I could not find any documentation on which names to use in the fromspace, tospace parameters (I have tried space:world, space:tangent and other combinations but just guessing here)
I am just trying to manually create Normal, Velocity and Depth for the camera coordinates, but I am having trouble understanding how to use Transform Vector.
