1. Open QAGame Editor
2. Create a New Material
3. In the New Material, Add a Constant 3 Node set to (1,1,0)
4. Add a Constant 3 Node set to (0,0,0)
5. Add a Constant 3 Node set to (0,0,1)
6. Add a Texture Sample Node set to any Texture
7. Layer the Nodes as shown in the attached picture

RESULTS: You lose the border of the Node and in the case of the Texture Sample, you lose the UV Pin Location

EXPECTED: You should be able to stack the nodes without losing details of the node.
