Creating custom lightmap for a mesh that will be exported to UDK
I have resently dived into UDK and have been trying to make a housemodel for UDK.I have A lot of problems from modular creation which i dont understand quite good yet.
I have a wall model with a multisub object applied with uv,s.ID1 and ID2,What i have heard its possible to create a lightmap ,Here is the part that confuses me.
Do i create a third ID or do i apply a unwrap modifier over the unwrap i created with ID1 and ID2 ?What i have heard its just making a flatten mapping for the lightmap?
Cant find any explanation or tutorial on this
Also I'm not sure how i would cut my model into modular pieces,Its so many ways .Floor by floor,or smaller sections,Should the windows be attached to the walls,etc etc....
