I think you are not inputing the path correctly, and you are not using it correctly when loading :
- going one director up in the architecture takes
if my shader folder is inside my src folder ( see picture )
, I can use this path :
filesystem::path path = filesystem::path("../../src/shader");
so you path, assuming that you have a src folder 7 folders up would be :
filesystem::path dirFolderColorShaders = filesystem::path("../../../../../../../src/shaders");
(which also means that you are outside your OF install and one folder up in the hierarchy btw).
- the path needs to be set in front of each name, so the vertex shader, and the fragment shader are being pulled from the same location:
Also, I guess you should try to check the excellent addon from @hrs on 360 Projection here, and see how he uses the filesystem::path to reference his shaders.
Hope this helps,
