How to generate equirectangular (sphere projection or single-image cubemap) UVs?
I’m trying to project an equirectangular texture onto an object based on normals. Here’s an example of one:
I know this can be achieved with six textures, a cubemap, but that’s way too many texture fetches and samples for my project. I tried using reflectionvector-node and some math and it’s almost perfect but my implementation seems to only use half of the texture and mirror the rest which still looks good, but, that essentially turns a 360 image into two identical 180 images. How should I approach this?
