No ‘scene.mvs’ file generated when running InterfacePolycam use parameter " -o SAVE/PATH/scene.mvs "

[wioponsen]

Describe the bug
No ‘scene.mvs’ file generated when running InterfacePolycam use parameter " -o SAVE/PATH/scene.mvs ".
if don't use parameter " -o ", it will save ‘scene.mvs’ file successfully in current folder.

To Reproduce
Steps to reproduce the behavior:

1. prepare polycam raw datas
2. running

InterfacePolycam -i polycam/ -o scene.mvs

3. .dmap could be generated, but NO ‘scene.mvs’ file

Expected behavior
Generate ‘scene.mvs’

Additional context
I noticed that apps/InterfacePolycam/InterfacePolycam.cpp Line 151

	// initialize optional options
	Util::ensureValidFolderPath(OPT::strOutputFileName);
	if (OPT::strOutputFileName.empty())
		OPT::strOutputFileName = "scene" MVS_EXT;

if OPT::strOutputFileName is not empty, it will add a ‘/’ in the end , causing failure in scene.Save Line 357 .

So, by commenting out this code in line151, the program will work correctly. Here is the code:

	// initialize optional options
	//Util::ensureValidFolderPath(OPT::strOutputFileName);
	if (OPT::strOutputFileName.empty())
		OPT::strOutputFileName = "scene" MVS_EXT;
