Hi, Im relatively new to unreal and im coming from an archviz background.
Im just wondering, what exactly does unreal do when baking lighting. is it generating diffuse textures with baked lighting?, does it generate a simple shadow map thats projected over the texture base?
Also during swarm baking what is happening in the ‘processing mappings’ phase? im having trouble where my scene is getting stuck at 99.7% for hours and hours. There are one or two 2048 maps in my scene that could be the root cause but im not sure?
Ive been through the lightmap densities and everything is green as far as i can see.
