There was a bug in P3dO 1.6.5 with the Rsr2Png converter. Probably the PNGs have inverted channels. This bug has been fixed. To fix it you should have the lastest Rsr2Png 1.2.6, see the plugin version number in the about box. Here's the link for the fix: http://www.senosoft.com/downloads/C3DRsr2Png165126.zip Then run Rsr2Png and convert back to PNG, then run Rsr2Png again with fix blank PNG option, last convert the PNGs to RSR. Maybe is the fix blank PNG step not necessary, I'm not sure. btw You don't need to close the window to save a PNG as an RSR. Just save it as RSR. Sorry for the bug, I will double check if it occurs from the Edit Image menu. Yarp
