In the exported .dae-file the texture coordinates S&T seems to have some sort of random at the integer part. The fractional part is sometime corrupt, due to rounding, since the difference between upper texture (S,T) coordinate and lower coordinate is greater than 1, i.e. stitch texture and not a single texture. Even if only a fraction of a texture is mapped. Can somebody explain the reason for this randomize and if there is a way to avoid it and how I can get rid of the rounding problem, see errorTexture.zip (120.3 KB) as example and look in the .dae-file .
