how could i remove those f#@°@@# splotches ??
this is not a texture problem (i tried without any). seems it comes mostly from the camera angle. but i can’t move it…
Is the geometry overlapping there?
no.
i used to manage to render it fine with an older release, and an other camera view.
the trouble is i can’t find the parameters i had again…
to you thicnk an irr map + photon map would work better?
No, photon map is not very good for exteriors. You could try lightmap it works well on exteriors. Hmm, not sure what might cause that for a test you could try setting your Secondary Rays bias (in the Global switches rollout) to somewhere around 0.001 to .01, this can help if the geometry was modeled outside of max and has some issues, the catch is that higher settings can cause trouble with shadows.
you’re right, with 0.01 this is fine!
thx a lot
