Does anyone know any tools or workflow for painting skyboxes? I'm working on a hand-painted style skyboxes and I find it very hard to paint the skyboxes using Krita on this: My paintings always end up distorted.
Take a sphere primitive, invert it, and then load it into a 3D painting app (like Substance painter). Paint your skybox on that, and then bake it onto a cube with a T-style skybox layout like you see above. The 3D painting app will account for any distortion.
EQs technique is probably the easiest way of hand painting directly to a cube map. Susbtance designer has panorama generation tools that'll help with HDR generation and will distort images for you. And I can't recommend lys highly enough for converting between layouts and generating the convolved maps you'll need for…
