OSPRay has issues
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
OSPRay really doesn’t work well. I have users that are interested in it, so I puttered with it tonight. I did the following:
Linux, local server, 5.1.2 (Kitware build).
Load bake.e. Utkarsh has this dataset.
Look at the object, and rotate it around. Notice what is happening to the lights. Notice that the diffuse light changes as you rotate it.
Turn on OSPRay.
Rotate the object. Nice that the lighting doesn’t change. In other words, the lights without OSPray are moving with my eyes, where with OSPRay, the lights are attached to the object.
Notice the center cone. It is black. This is wrong. Turn off all of the input blocks, with the exception of the cone. Notice the cone is still black.
