Hi guys if anyone is in need of converting a multi texture model to a single texture atlas i would be happy to help out, as you can see from the image below i have a building that uses 15 individual textures. Now what it does is it breaks down the model re-maps it then bakes it so you only have 1 texture file this will reduce memory and draw calls.
Original texture usage 31mb
new texture usage 9mb
The process usually takes 2-3min and outputted to any format also note the more textures the model has you may lose some quality but i found anything around 15 files or below is ok, below is individual vs one texture
