I’m looking for some enlightenment, I’ve got a building, modelled in Max at real world scale and brought in to Unreal where it’s scaled down to 0.01 to be about a meter long when it’s in AR, the thing is the building light maps build well when it’s 1.0 scale in the scene, but that obviously won’t do once in AR as it’s huge, when it’s scaled down however the light map build is very poor, the lightmap sizes are around 512 and the UVs are all good as it looks fine at 1.0.
Is this down to the static lighting level scale? Seeming as the meshes are so densely packed at 0.01 scale I should lower the static lighting level scale down to say 0.1? I know it’ll really hit build times but I have power for that.
I have lightmass importance volume set up but would ambient occlusion also cause problems at such a small scale?
I tried building the light at 1.0 scale and then setting world scale at run time but that seems to completely remove shadows once world scale is changed.
Ive attached a screenshot showing the poor ass light maps at the moment, this was done with a static lighting level scale of 1.0 and preview settings.
Sorry I’m not so comfortable with lighting in UE4 and this is yet another new thing I’ve not dealt with before, any help would be most appreciated however, it really will.
