To have a reference of what I had to look for, I performed tests in Sunflow directly by editing the example_scene.geo.sc file.
I have found that vertices are only well taken into account if they are grouped into a single object defined in the .obj file.

By launching the rendering several times, sometimes the triangle mesh light is not well applied.
I think I should put my method searchVertices (light) elsewhere than in exportLightSource especially since there is redundancy with some methods already present in the PhotoRenderer file.
