I have a multires object and will bake the normal map to a low poly object with cycles normal bake function. So I unwrap the low poly .set both to smooth shading. Then I generate a UV texture with aplha 32 float 2048*2048.
I try first the Uv image non color color space option then I bake without saving. The baked texture look proper blue all okay. I apple a normal map node setup with image texture node.. On that image node I choose the generated texture. Cycles renderpreview show the normal map efect and it look good. But I dont choose non color. So I try non color on the image texture node but now the normal map looks ugly wrong now in the 3D render preview ???? ,?
So I creat a new texture same settings..2048 alpha 32 float..Name it .. Choose the default SRGB Setting and bake without saving... The first Problem or difference I notice is that in the Uv image editor show the baked normal map in a lighter color ,not so proper blue look more flatt near pink not türkisJ.. I hook up the Image texture node back to the normal map node (detaced before bake) and choose the new generate baked normal map texture . no the 3D render preview I see the seams with that texture and non color option will not work..
So I try the baking again but with saving..both texture setups again . So the problem with saving is, after a reload the baked Maps both baked with different uv texture color space option looks outwashed not proper blue türkis..looks Totals flatt and pinky... (Im novice but it looks not normal not good ) I set up the nodes I choose the normal map Image and non color Data option but I see the seams in the 3D render preview and the normal efects looks ugly..
So I try different Uv texture color space option before baking for the uv Image texture but the propper Uv map comes only out when I save not the image before baking and the texture must use non color for colorspace.. Otherwise baking to SRGB saved texture bring's out a flat pinky normal map..
How I twisted and turned (sagt man das so?) baking will not work on win 7 64 bit system ... Any idea would be great to find the Problem.. Sry can't upload file...or screencast,bad Internet conection at the Moment..
