Its a good question. As im trying to isolate why some models disappear and others do not, after baking lights in F3 lightmap mode.

I am not seeing any problem light mapping models I have stacked UV's in.

I did notice one of my custom models had a few parts missing using DNSI textures and the entity_basic.fx shader.
Testing this more to see if I can spot a pattern.

As far as i am aware the lightmapper generates its own UV's for objects so it shouldn't be a problem. However my experience has been that sometimes it confuses the lightapper and either makes objects disappear or randomly makes some models darker or lighter.

Quite a few of my models (DNS and PBR) have stacked uv's and they seem to survive the light-map process. I always bake F3 for lights.

Haven't tried with beta yet, but will test tomorrow.

posted in another thread but if you put pbroverride = 0 in the setup.ini some models completely disappear after the F3 light baking process. Not sure why this is occuring but could be related to overlapping UVs?

I thought pbroverride = 1 was basically to let GG know your level contains a mixture of DNS and PBR models (which applies to most of our levels tbh). pbroverride = 0 means you want all of your level to be considered PBR, meaning any remaining models that are DNS are disregarded during the lightmapping - that might explain why they disappear, but only after lightmapping.

Ok I got a answer from Preben

Pretty much what @ Belidos said

Quote: "Yes it should support stacked uv , as it will use the same UV and only add a additional UV set for lightmap. "


But will need testing , when my comp is back together
Thanks for the answers guys
