Unfortunately this seems to be a lot of extra work at this point just to get my sprites to look normal under this lighting engine.
At this point I don't know if it's worth it to go forward with this lighting engine. It is way more complex than I thought it was going to be. My main goal was just to have lights at certain depths in an isometric environment but now I need to download materials, normals, etc. and I can't even get that to work.
Our game is going to consist of a lot of different sprites and if I have to generate different images for every single sprite I want to look normal under the lights then I'm not sure this is a good idea.
I don't know why but on the PBR Packer program, pressing "Save" sometimes doesn't do anything, nothing gets created on my file system.
