Space limit is a little 3D demo (so no gameplay yet) inspired by Kerbal Space Program.
If it's too slow in your browser, try directly in Pico8
There is nothing in the sprite/tile data, the code is (realy) messy and triangles can only be monochrome.
For this project, I made a blender exporter (based on the .ply one) that can be found here
I also made a mesh converter to vertex/index string (one byte per location, scale limited to 2.5 around origin) to import in Pico 8. I made it in Javascript (If some people want it, I could port it in the blender exporter instead).
here is the converter from obj, and here for my custom format from blender.
Have fun !
