Hi~Recently I downloaded some skined meshes for my demo,some of them were mirrored and just have a half of contents in the texture(since the UV in mesh were also mirrored). Then I found a problem that when the mip level increases,a black line appears in the middle of mesh.Is it because the GPU samples some background color in the border of the actual image content when I sample the smaller mipmap? How can I sovle this problem ? Do I need to make some bias or clamp the mip level ?
