Hello y'all , let me jump straight into the problem I have made a mesh body, at the neck of which the vertices are perfectly snapped/aligned to those of the SL avatar neck. When I put it on and enable shadows, there is a seam, even after copy and pasting the vertex normal value for every vertex from the SL avatar neck to my body's neck. http://gyazo.com/eb7b45f7f9047a9389e9796deae40835 Trying on another mesh body, it does not seem to have this issue. http://gyazo.com/3b27dfa46481a7518d5ddb617d14876a The vertices at the neck are rigged to the mNeck and NECK bones of the sl fitted skeleton, so both to the fitted bone that gets affected by the slider Body Fat and the bone that gets affected by Neck Thickness. What am I doing wrong? Thank you in advance <3
