Unreal Materials: Access texture via raw integer coordinates.

Generally, Unreal uses float UVs to access any texture. Sometimes it's needed to get the exact texture value at a specific pixel via integer coordinates. A custom node in combination with a Param Tex Object can be used to achieve this.

Inputs to the custom node:

• Integer coordinates xyz (if not hardcoded)
• TextureObjectParameter node

Output: CMOT Float 4
