Hi,

I would like to use a 16bit grayscale PNG image, that I generate and export in MATLAB as texture (see the 8 and 16 bit version of the texture file in the attachment patternfile16bit.png, and patternfile_8bit.png).  In Blender it is working nice. The 8bit grayscale PNG image works also nice in yafaray (yafaray_8bit.png). The 16bit grayscale texture looks very strange in yafaray(yafaray_16bit.png) , it looks like some kind of  Moire pattern, or interference pattern. I also tried to use the exr  ouput format of yafaray, but it looked the same. I guess there must be some problem with the png import function where the 16 bit images gets processed in yafaray. Is there any way to use 16bit grayscale or 48bit color images of any format as textures in yafaray?

My system: is 64bit Ubuntu 9.10 Karmic Koala

Kernel: 2.6.31-19-generic

yafaray version: 0.1.1

Thanks, best regards,

Zoltan
