Hey everyone, I want to propose a change the default margin value that is currently used when baking textures.
The current margin of 2px is no where near enough and really doesn't help anyone due to the fact that it only is enough for the initial baked texture and not for any further mip levels that may be needed. As I'm sure some of you may be aware, you need at least 1px of margin per UV island to be correct for each mip map level as the texture is resized down, in order to stop the background colour from bleeding into the UV islands. I would recommend using a value of 16px as the new default as this would allow for 3 mip levels in addition to the initial bake, as long as the background colour is correct) which should be enough in most cases as the texture is resized down (16px>8px>4px>2px). Ideally of course we would set the margin so high that there is actually no background colour, but I don't think that many people would go for that as some feel that it makes the texture look messy, however irrelevant this may be, some people do care about how their textures look even if you will never see margin on the final mesh. ;) Please take a look at the link below for an example of what an incorrect margin value can look like when viewed on your mesh. http://blenderartists.org/forum/showthread.php?279870-seams-artifacts-with-tangent-normal-map-in-blender-and-unity For clarification, this is applicable to all baked textures, not just normal maps Cheers, -Andy _______________________________________________ Bf-committers mailing list Bf-committers@blender.org http://lists.blender.org/mailman/listinfo/bf-committers
