Fixed Normal Map Bake Skewing Polycount Discovered a new way to fix skewing when baking my normal map detail in substance painter and wanted to share for those who have fixed the problem or have ran into the problem of normal map skewing. This means a normal map baked in one application probably won't shade correctly in another. artists must do some testing with different baking tools to find which works best with their output.
Fixed Normal Map Bake Skewing Polycount Carlos lemos has recently finished his 4 part tutorial on normal mapping and kindly allowed us to repost it on 80 level (originally posted on artstation). in this article, read about what normal maps are and the process of baking them. Normal maps are great, but they aren't magic. you will get some stretching at those corners, especially since your low poly object is outside of your high poly and if you are zoomed in like you are. Learn how to bake high quality normal maps for 3d models. includes tips, troubleshooting, and software settings for bevels and planar details. It's typically best to use the complete mirrored model to bake the normal map, not just the unique half. to prevent the mirrored uvs from causing overlaps or baking errors, move the mirrored uvs out of the 0 1 uv space, so only one copy of the non mirrored uvs is left within the 0 1 square.

You should avoid changing the uvs after baking the normal map, because rotating or mirroring uvs after baking will cause the normal map not to match the tangent basis anymore, which will likely cause lighting problems. Hello everyone! i'm having trouble with baking in substance painter. a part of my high poly mesh is being "pulled" towards an area of my low poly mesh. any suggestions on how to fix supplement this problem? thank you!. @polyhertz fixed now, all the images should be there. they got lost when dropbox nuked the public folder feature, but should be saved onto polycount's servers now. Take a look at how your low res mesh looks with no wireframe, you may notice that same artifacting is visible in your shading. the issue you're seeing in your normal map is the bake normals trying its best to counteract that bad shading.
