Ugly Normal and Displacement Maps

4 posts in this topic

Hi folks,

I made a model in 3DC for use in C4D.post-1430-0-25826800-1331246550_thumb.pn

The normal and displacement maps I exported had the following effects:post-1430-0-76200400-1331246662_thumb.pn

My question is, can I export decent maps like I have done many times before? The displacement looks like broken phong and the normal map creates seams where there are none.post-1430-0-78952700-1331246948_thumb.pn

The color map saved they way that is expected. Any suggestions will be gratefully received.

Tony

Hi Tony,

Have you tried turning on the "sub polygon displacement" button in C4D?

Sub Polygon Displacement subdivides your mesh before displacing it, I usually turn it up to 2 times.

You should also try turning on "round geometry" which helps getting rid of those blocky shapes.

I hope this helps.. :)

Hi tony nemo.

Can you post a sample of displ map?

How did you bake it? If I recall correctly, it's possible via MV mode only!

Hi Johnny,

thanks for the tip! I was using SBD but "RoundGeometry" cleaned it up. But the image quality isn't improved over the straight color channel so I don't need the the render time hit.

Michalis: I guess your right but the menu in the paint room shows "Export >Displacement Map", etc This had no effect on the appearence of the model in C4D except when it was improperly employed by me. When I did it correctly, there was no discernable difference, with or without. The normal map again doesn't do anything except provide unwanted seams where none occur in the UV map.
