@PurpCat Come to think of it why don't devs just build on the FOSS id tech engines in this day and age? There should be plenty of docs and support by now and it runs everywhere without the bloat of stuff like Unity, UE, etc. (most of which is completely unneeded for smaller projects)
some games hilariously miss the mark though, the textures should be approximately the same resolution and the triangles shouldn't be too big so that the texture warping doesn't get too obnoxious (the ps1 programming guidelines suggest dynamic tessellation)
