Is anyone aware of a script similar to https://chemikhazi.itch.io/sprytile for 3ds max? I currently have a city built with Ghost Town, and while it does a good enough job adding textures via material ids, it doesn't support texture atlases. I've tried using http://www.scriptspot.com/3ds-max/scripts/texture-atlas-generator…
Ok so you need a texture atlas tool. You would have to export a section of your city, and the tool would pack all the materials into one texture, while also rearranging the UVs to match. IIRC Nvidia had a tool for this in their SDK.
