Made some progress: Turns out I was not able to run Intel's own OSPRay example as well. I realized I had another version of TBB on the path which was superseding the TBB built as part of OSPRay. After fixing that issue, I am now able to run Intel's example, but opsrayplot still fails with a different error:

#ospray: INITIALIZATION ERROR --> could not open module lib ospray_module_ispc: The specified procedure could not be found.

#ospray: INITIALIZATION ERROR --> could not open module lib ospray_module_denoiser: The specified module could not be found.

Could not load denoiser 
#ospray: INITIALIZATION ERROR --> could not open module lib ospray_module_ispc: The specified procedure could not be found.

#ospray: INITIALIZATION ERROR --> null handle provided to ospDeviceCommit

This is due to the fact that ospray loads compiled modules dynamically. I think the fix will be to make sure that the directory containing libospray_module_ispc.dll is in your PATH environment variable.

I already made sure that it is. It's in the environment PATH as well as MATLAB path. :(
