I found that hi-quality photographic renders (V2.3b21, quality settings 3 and 4) often exhibit horizontally stretched wall textures, in which the texture is not tiled / repeated over the course of the wall, but stretched to cover its entire width. Vertical tiling, however, works fine. This problem only shows up in hi-Q settings (3 and 4); lo-Q settings 1 and 2 (just like the 3D view, which uses quality 1) are fine. (system: XP SP2) Of course, a hi-Q rendering is the final result that all previous effort is aiming at, so I am quite lost here...

At first I thought the funny-looking textures resulted from interference patterns on the lo-Q settings, but hi-Q with filtering and anti-aliasing produces exactly the same result. So I cross-checked by exporting a part of the wall to .OBJ format and re-importing it. Voilà: the re-imported wall rendered just fine, while the original wall still showed the stretched texture.

I have as yet not found any pattern to where and when exactly this happens: I had slanted walls and walls which did not reach the maximum height of the entire model; I checked where the walls were facing, which side (left/right) was affected, whether the faulty wall was connected to others or stand-alone, whether it was connected to straight parts or corners... There is no criteria I could find that shows consistently correct or faulty behaviour here... [:(]

I suspect this may have something to do with the "do not re-start the texture at every wall opening" fix you did recently - although I still have one single spot in my model where the left side of a window does re-start the texture! (maybe that's the problem?) I tried refreshing the faulty wall, even deleted and re-did it completely - all to no avail, the window still breaks the texture continuity. [:-/]

I would post pictures to illustrate this, but I don't know how to upload any, and I have no webspace available. If I overlooked the obvious "upload" button, I will gladly provide my faulty renderings. [:)]

Anyway, thanks for your constant improvements of SH3D. [:)] Maybe this one can be the next. [:D]
