Light baking for multiple object versions

Khadyko

Hi! I have a feeling that's a stupid question, but...

I have a landscape and a few types of the same building standing in it's center. Each type has some differences and could be switched by customer in final app. Question is - how to build a static lighting for that? I mean that all types are standing in the same coordinates and only one of them can be visible at the same time. How to make engine ignore affection of the building types to one another during baking?

Thanks!

There's capability to swap out lightmaps, which is sometimes used for different times of day in the same level, etc. If you're swapping out a singular building, that might be an appropriate solution. However, multiple swappable buildings affecting shading on each other, maybe not.

I take it dynamic lighting is not suitable for purpose?

Try lighting scenarios but I'm not sure if this will work, because its used for a slightly different purpose:

If this doesn't work, then there isn't really a solution for this, and you should consider switching to dynamic lighting.

Thank you, guys! 

Lighting scenarios seems to be a nice answer for my needs! I'll go that way.

I can't use only dynamic lights in that project due customer's restrictions - app should work smoothly even on a potato office PC with build in graphics. Models are petty heavy and I'm trying to optimize at least lighting to make it work.

Thanks again!
