Hi i have an image and use it as texture. i applied to a cube and setup uv. Go to texture paint and paint using green brush . All the paint looks good in the viewer, but when i save all images and check the folder where the texture is saved , i only see my stroke with my original image become black. Is this a bug ? Does anyone has this experience ?
I've just found the fix for this. I realize that it happened when i use 16bit TIFF file as texture map. So everytime i do a texture painting and save the image, it will save only my stroke, while the original image become black. Then i fix this by using 8bit, so i convert that 16bit into 8bit TIFF then reload that texture map and it solves my problem. I currently use 2.79 , so maybe this is a bug.
