Bump Map query

Hi,

I am trying to give some definition to my roof sheets with a simple bump map but the resluts are far from desirable.

Am I doing something wrong?

Test both on Sp2 and Sp3

The attachments show the different results obtained by only rotating the view and moving the camera further away.

I also tried two slightly different bump textures.





Looks ok to me for the given maps; keep in mind that when you get away from the maps they will be blurred by the bitmap filtering.

Best regards,

You are also using Adaptive Subdivision for your AA method on the 3rd shot. Try switching up the min/max, or using Adaptive DMC to get better AA on those fine lines.

Okay here is more the part i don’t get. My understanding is that with the bump map white areas will be “raised” higher than grey or black areas, but that is not what i see in the attached images.

What should be raised areas is rendering dark.
