paraview parallel overlapping when raytracing and opacity <1

gilcu2 · October 15, 2019, 10:57am

Hi, I am trying a parallel rendering with raytracing by ospray. When the opacity<1 I get an overlapped image. I tried a clean to grid filter but the same result. What can I do?
Thanks
Reynaldo

Hey Reynaldo, OSPRay has a ton of issues when using parallel rendering (multiple processors). Try running this same thing using a single processor and see if you have the same issue.

In one processor works perfect.
Thanks
Reynaldo

Glad I could help. I’ve run into this same thing multiple times.
