OBJ file with Material link not work if Filename contain spaces.

[Mannshoch]

If an OBJ file is created with a Material.mtl, the material.mtl do not work if the material.mtl and/or the filenames of the textures contain spaces.

If you rename the file, open the .obj and.mtl with texteditor and remove the spaces. it works in Meshlab.

Not work:
test file.obj
test file.mtl
test texture.jpg

*.obj File

mtllib test file.mtl 

to

mtllib testfile.mtl 

and
*.mtl File

map_Kd test texture.jpg

to

map_Kd testtexture.jpg

Works correct
testfile.obj
testfile.mtl
testtexture.jpg

confirmed.
I fixed the importer in the VCG Library, now it seems working.
I am not completely sure the format DOES allow for space in names and IDs (e.g. blender does add an underscore, when exporting), but this may solve compatibility with less strict exporters.
It will be available in the next MeshLab release (around 1 month).

This still seems to be a problem in Meshlab 2022.02, so maybe the fix hasn’t landed in a release yet?
