Hey everyone,
sadly I am still didn't get any further with my "texture bug". I really don't succeed in locating the error because it appears randomly and also takes the leafs away from my forests (Plants are set with Itoo forest Pack). Here is what I've already tried:
Increasing the rayepsilon value didn't help.
Then I checked the info channel kernels. The "geometric normals channel" looks quite normal to me, but
the "Shading normals channel" gives a similar picture as the faulty rendering. I attached three pics, so that you can have a look: "01_error", "02_error_geometric normals" and "03_error_shading normals".
Then I found out that the error changes with making or unmaking things movable proxies. I attached another picture ("unmade proxies") to show you that the materials shown in the rendering for the front of the house and the windows are now shown differently after I unmade the belongig objects movable proxies (rest of the scene are still proxies and I also need most of them to be). I attached another two pics to show this: "04_unmade proxies" and "05_unmade proxies_shading normals".
The scene is huge (2,4 GB). Is there a possibility to send such big scenes? The problem is, if I reduce the file size by deleting geometry, the error doesn't occur (as soon as I hide some high-poly geometry, the error doesn't appear in the rendering).
