TextureMesh Segmentation Fault

[yinbc]

Issue Description:

I encountered a segmentation fault error while running the TextureMesh module in OpenMVS version 2.3.0. The process terminates unexpectedly after "Segmentation fault (core dumped)". The following is the output from the console.

In addition, ply can be successfully generated without "--export-type obj".

Console Output:

Update, I found that the program crashes when executing "const auto texIdx = faceTexindices[idxFace];" in Mesh::SaveOBJ. After testing, I found that faceTexindices is empty. What is the meaning of faceTexindices?

Are you sure you are using the latest develop branch? Pls send the data and command line to reproduce the crash.

Hi, I want to use this repo to extract texture, but I got failed when building the main branch. will the develop branch solve my problem?
