The clipSpaceTransform matrix cannot fully transform the vertex position #7657

⚠️ Issues not using this template will be systematically closed.

Describe the bug I need to set gl_Position in the vertex shader. A workaround is to set the material.clipSpaceTransform matrix in the device domain. However, this matrix cannot affect the z component of the vertex; it can only transform x and y.

To Reproduce Steps to reproduce the behavior:

  1. set material use device domain
  2. set the material.clipSpaceTransform matirx,but the matrix cannot affact the z component of the vertex

Expected behavior The material.clipSpaceTransform matirx can affect the z component of the vertex

clip space transform can affect the Z component. In the device domain you can also use the world from clip transform matrix for this.
