@binhhuyle Thank you for your reply! zero matrix problem actually happens in solveP function: z=q2[np-2]*( //Re-project (q2[np-2].transpose()*indexing_row_col(aTa, idx.head(np), idx.head(np))*q2[np-2]).colPivHouseholderQr().solve( //A q2[np-2].transpose()*(indexing_vector(aTb, idx.head(np))-indexing_row(aTa, idx.head(np))*x) )); //b the matrix (q2[np-2].transpose()*indexing_row_col(aTa, idx.head(np), idx.head(np))*q2[np-2])...

@robertjoosten Hi, Can you supply the data(aTa, aTb, x, idx, np, affine, p) passed in solveP?

> 6.15434e+255 well, definitely your sparse matrix w is wrong to make it value(6.15434e+255)，you can check the fbxreader part to see if you get right weight matrix w

Thanks for the replay!
