seam leveling dose not work

[Rogers34]

Dear friends, thanks for your brilliant work! I use voxgraph to generate mesh which use tsdf model. And I use texrecon to texture the mesh. However the result is not as expected. There are many big mosaic on the mesh. It seems that the seam leveling dose not work. Could you give me some advice to solve this problem? Thanks a lot!

Seam leveling requires connectivity between the faces and it seems like there are a lot of gaps.
