Using pickPlugins() function we can get Node objects intersected at the given pixel. We interested in getting information about the material assigned to the clicked object. Usually it's not a big deal, but if we use GeomMeshFile with VRMesh that has multiple materials assigned to it, it's not so trivial. The assigned material will actually always be MtlMulti. It would be nice to have a function that would give some additional information about the picked object like material id or shader set name. Is there such a function available in the API or are there any plans to implement it?
We also tried to use a workaround and create a RenderChannelExtraTexInt with material_id from the sampler. It would work for CPU, but it is currently not supported on the GPU (and that's what we have to use). It also has some performance overhead and affects the interactivity, because of the extra image buffer that must be updated. So some special function would be probably a better solution.
