Hi everyone,

I'm holding back the release of v2.5 until I fix one last bug. It's been reported that under certain (unspecified) conditions, the texture map has black lines running through it (see screenshot). I've been trying all sorts of wacky combinations of settings to reproduce this fault, with no luck so far. Has anyone else seen this problem? (specifically; dark lines in texture or light map). For special bonus points, I would be ever so grateful if some users could download the latest Pro dev build (RC3.3) and give the texturing a bit of a thrashing (high TX resolutions, like 8x/16x/32x). If you do find a problem, please save the project and send me the map definition file (extension = '.def.xml'). Any help would be hugely appreciated.

Best regards,
Aaron.

Update:

I think I've found it. It's just the per-pixel texture generator. Very odd indeed - the dark bands (they're not actually black) aren't associated with high-res textures as I thought; they may be associated with large heightfields instead. I wonder if it's to do with the mip-mapping...?

I've noticed that when I import a non ^2 map (4097x4097) in the final texture (at 1x !) there is a single black pixel at row 2 and column 4096. There is a texture at 1 and 4097.

Not a problem since I just crop the texture by 2 pixels and resize. The difference isn't going to be major!

Hurrah, found it! It was the light-mapping algorithm, not the texture-mapper. A few more tests and release 2.5 should be good to go.
