I have a big scene. Houses, roads, trees and etc. It’s really big so dynamic shadows and lights is a bad idea. So I’ve chosen lightmaps.
Now, I have to:
Make a lightmap-camera(no idea)
Collect all data about shadows&lights(my mind starts to overheat)
Delete all nodes from the render tree but make the lights&shadow on their place(I am feeling like beeing fried)
Capture this at twice the resolution of the scene(my body blows up spreading every atom to the unvierse)
Add the picture on the ground(pretty hacky, but possible)
First I thought it will be fun to do it. But I stopped at the lightmap camera and never found out how to do it.
Maybe you could help me.
