First of all, thank you so much for sharing this code! This is the first and maybe one of the best photon mapping project I can learn in GitHub!

But I want to ask something about how to run this solution: I've finished CMake build and enter the .sln, but after I clicked Local Windows Debugger (under Release mode and x64) on solution, it shows that I can't load the obj file.

I tried moving the model with materials to Include Directories, but that didn't seem to work either (since I haven't used tinyobjloader before, so forgive me if I'm wrong) I checked GitHub's tinyobjloader repo related content, but it didn't solve my problem.

Can you help me? Thank you very much!

I don't know if it has any effect, but I set project main not ALL_BUILD as start up project, and I put the model under /volppm/build/examples/main.dir
