Hi all, I am occasionally getting these odd diagonal lines in my images. I was wondering if anybody knows why and also what i can do to get rid of them. I have tried everything I can think of but they won't go away. Attached is an image where you can see these lines clearly on dresser and wall. Ideas? I've moved the lights, changed them, reloaded textures, reloaded image, once they are there that's it. This time I just decided to live with it but I'd like to know how to rid myself of this annoyance. Thanks in advance. Kiera

that is called "moiré", and it is caused by interference between the texture and your actual rendering. you can only avoid it by either using "full" colour (without texture mapping) or with higher resolution textures.

sometimes changing the camera position also helps, but usually the moiré patterns appear on the very next object then ...

Have you tried increasing the Map Size for the lights casting shadows..? I have found that using a map size of 512 and a Shadow setting of 0.500 usually elimanates those type of lines on surfaces.

Make sure that the wall and the dresser drawers have some acutal thickness. Shadow maps work a lot better when there's some real substance to an object, just a single polygon layer or coplanar double-sided polygons can cause such artifacts. In the case shown, the wall could also be fixed by unchecking its "cast shadows" flag. If everything else fails, you can still crank up the "min shadow bias" on that shadow casting light or switch it to using ray traced shadows.
