Ok, so bare with me here, this might get a bit messy…

I want to know if it’s possible to use multiple bitmaps when tiling. I know the multi-map node exists, as well as the UVW randomiser, but for the life of me I can’t figure out how to get a random selection of the multiple bitmaps tiling across a texture.

I don’t want the randomness per primitive, or per instance, but when the tiling is happening…hopefully the video explains my situation best.

Thanks!

Randomizer is a good choise for your task, you just need to throw multi map out of equation and add your bitmaps to single sheet. Look at the attachment. I also highly recommend to watch official Corona tutorial about UV randomizer - it’s full of very useful information.

Another option would be to use BerconTiles + Multitexture (in BerconTile mode) if you want to keep single textures. And a third: slice the surface, break vertices and then use Mesh Element mode of CoronaMultiMap (fixed tiling here though, but maybe an advantage if you want to have full control).

Good Luck
