Reinhard Posted June 12, 2010 Share Posted June 12, 2010 (edited) Hi, good people. I'm working on a given picture, which is derived from DDS (DXT) format. It is a texture for a 3D game model, and comes with heavy use of transparency. As long as I work with layers, everything is fine. But when I save the file, the result is a picture with some black markings, which aren't in the original. These black spots are visible in PAINT.NET, but only after single layers are merged or the whole bunch of layers is flattened. The damage is more easy to spot when I activate a transparency plug-in. Now even more overall changes are visible. I made a before/after picture, hope it makes a bit more clear what my problem is. The problem isn't caused by this transparency-tool, in fact it occurred as well before I installed the plugin. I have used different parameters for blending, like "normal", "additive", "multiply", or "overlay". But this shouldn't be important anyway, because the different layers are cut-outs of the original, so no active layer overlaps with another. The changes I have done in the layers are modified values of the "hue". Can this have any impact regarding transparency? Any thoughts or suggestions? Thanks for listening.

warfighter67 Posted June 12, 2010 Share Posted June 12, 2010 (edited) The layer on the bottom has to have default settings or else merging down screws up the settings. One way to fix this is to create a new layer on the bottom of the two layers you want to merge, and merge the bottom layer down into the new layer.

Reinhard Posted June 13, 2010 Author Share Posted June 13, 2010 (edited) Thanks for the hint, Weylin, didn't knew this. But unfortunately, this doesn't help in my case. In fact, all my layers were in default condition (despite of the name) when I faced the image corruption the first time. I just re-tried, and followed your advise to create a new bottom-layer, but it doesn't do the trick for me.

Sarkut Posted June 19, 2010 Share Posted June 19, 2010 Reinhard, What version of Paint.NET are you using? Current version is v3.5.5. ============================ Try running PdnRepair: Program Files/Paint.NET/PdnRepair.exe Then turn off and reboot your PC.

Reinhard Posted June 19, 2010 Author Share Posted June 19, 2010 (edited) Hi Sarkut. No, a repair doesn't did the trick. As I expected, because in advance, I already did a full deinstallation and reinstall. But it is nice to know this option exists. Version? I always use the latest release. I just installed PAINT.NET on my netbook, for reference. Same problem. If anybody is curious to see the image I was talking of, please see the for attachment. Thanks. EDIT: Sigh. I managed to ignore that the attachment doesn't worked well. My clumsy fingers on a tiny new netbook... The file is to big anyway, so here is a direct link: please download it here, if you like (929 KB) Edited June 20, 2010 by Reinhard Quote Link to comment Share on other sites More sharing options...
