Strange color in lightmap with 1.46.05 [lot images]

[vergefio]

Hi guys... I'm having this issue with lightmap in my latest work. If i set subdivisions from 400 to 600, lightmap will be fine, instead if i set higher value i get strange color:

This is render with lightmap scale set to screen with 600 subdivisions:


"screen" scale with 1200 subdivisions (all other parameters are the same as above)



"screen" scale with 1000 subdivisions (all other parameters are the same as above)




"screen" scale with 800 subdivisions (all other parameters are the same as above)



So i tried to set "world" scale with 1400 subdivis and this is the result (almost clean, but see in the window):

Hi Vlado, all material are vraymtl, a couple of these are blend mat with two vraymtl each.

Perphas, blend mat cause this issue... i'm going to replace them with vraymtl... i'll keep you posted

ok, I tried to replace those mat with vraymtl and get the same issue... so i tried to use "override mtl" and all goes fine... mmhh... i have to find the "wrong" material...

BTW: nice scene!
