I've no problems with rendering, just as long as an openGL window is able to open on the screen (I don't even need to render directly to it i.e I can set view.UseOffScreenRenderingForScreenshots = 1 so the window opens but is black)
I had been trying to prevent this window opening to allow scripts to run in the background. I get output for all cases except where I use the --use-offscreen-rendering at the command line for pvpython or pvbatch Thanks, Lucy -----Original Message----- From: Kevin H.

It does not have to be a useful rendering just take a screenshot of the sphere source. Then if that works and if you're doing volume rendering or something more advanced, then try to make the rendering closer, a little at a time, to what you are trying to do for real. The Paraview GUI switches to offscreen rendering to make an output image, but there is a check-box to turn that off and on. The problem I've seen where the output images were garbled ( not as badly as yours ) would happen whenever paraview or vtk took a screenshot. It did not matter if I used the GUI or not, offscreen or not, nor if there was a screen attached to the X server. > As a work around, I have output the openGL window to a secondary screen > (in a similar manner to that you described in a previous post yesterday) > which is working fine for my purposes. > > Lucy > So everything works as long as the rendering is displayed on an actual monitor?
