To edit scene (3D area), go to the objects sprite inside. WASD to move and arrow keys to look around. EQ to fly. Pointerlock variable is for Turbowarp experiment only (always have this at zero if not using experiment). Use Turbowarp if you have wits, or this will blow your computer to bits! https://turbowarp.org/1252864080 Tutorial for loading textured .obj files: https://scratch.mit.edu/projects/1194975710/ Add textures with this: https://xeltalliv.github.io/ScratchTools/Img2list/#dc1 Move your cursor to the left of the screen to change sliders. Now uses a Z buffer, so billboards and ellipses had to be cut out, but I don't think those are the most important things for 3D rendering. Render sky variable options: 0 = don't render sky or ground 1 = render noon sky and ground 2 = render sunset (lighting will still be top down) Do you want to import an obj file? Click see inside, and show the lists "obj data" and "obj.mtl". Next right click and select import. Turn off filters and select files. Import complete! Don't have an mtl file? If the obj does not use the "usemtl" tag, then you can use the "create material" block in place of the "import mtl" block. These are under the block definition "update objects". Use Turbowarp (I am not responsible for computers wrecked, blown up, burst into flames, or otherwise destroyed by not running on Turbowarp): https://turbowarp.org/1227542010
Special thanks to @Eliguy12 for fixing an error in the find color of texture part of the filler, and to @maDU59_ for looking through my mess of code to fix the lighting!
