That's a fantastic write up thank you so much for sharing, and yes your correct it wouldn't add another draw call. I was wrong about that. I don't know why my brain doesn't operate on all 8 cylinders all the time. That's why I just love posting on PC always keep myself in check :)
As far as I know it depends on the engine. Some engines do create an atlas texture for their lightmaps, others don't. Also keep in mind depending on your lighting model. Dynamic lights can have huge overhead because they can add an extra draw call to whatever they interact with. So the drawcall cost in that case would be…
I am thinking performance compared to say unbaked ambient occulsion, the pros/cons over using vertex lighting. Also, a dominate directional light casting dynamic shadows on everything - is that a costly process compared to lightmaps? jocose: very good point about draw calls, I didn't think of that. That could end of being…
Depends on how the engine handles things and what platform your running on. However, that's the canned answer. There are some things that would be universal issues you just need to look at the engine/platform to determine how much of an issue they are. The two things you want to look at are: * Memory * Drawcalls ( EDIT: I…
