I have been following along a gamedev.tv tutorial and I am trying to fix my normal maps. I also have this strange leaking spot on my mesh. I'm unsure what would be causing that issue. However, my main issue is the glitching on the normal map and to have a better understanding of how to correct it. I have tried to measure the correct distance for my extrusion when baking, but my low poly would never appear under the high poly. How can I fix any of these issues?
My second issue is in this picture when I select my low poly version of my high poly it sometimes doesn't appear correctly. Also, it never has an orange outline around the character that I have created like with the high poly version. Any idea how I could fix this?
