Ok, so im looking to make a material which;
- allows 100% of light to pass through unaffected. As if the surface was never there.
- allows normal textures to be applied as usual whilst looking as it should ( diffuse,normals,roughness, etc)
Blender 2.80, using cycles.
I made a mini demonstration which kinda shows what im trying to do. Say for example i want to have the light travel through the square hole like the cube on the right whilst also having the green square at there at the same time.
I hope this makes it easier to understand what im trying to do.
Im not even sure if such a thing can be done at all which is why im asking to see if its possible. I seen in one of blender guru's videos he managed to make glass which was able to do this but im not very knowledgeable with the node editor so i wasn't able to modify node setup to meet my requirements.
