Is there a better place to put this hlsl file?

| The Imposter UV Node calculates the billboard positon and the virtual UVs for sampling. |

How about we say: "The Imposter UV Node calculates the billboard position (fix the typo in this word) and the UV coordinates needed by the Imposter Sample node." We need to indicate that data output here is intended specifically for the Imposter Sample node.

Should this be an array texture?

in the current set up it needs to be a single texture split into frames.

I reviewed with Tracy live. Main discoveries are:
- Align heightmap port naming with the existing Parallax node.
- Texture size allows user input though would only work with square of 2s, something we might want to handle more elegantly, i.g. change the input field to dropdown selections. And user may have difference resolution on base color vs mask textures for example.
This is super valuable work and useful for users, so great job Tracy! LGTM!
