[vtkusers] another vtk error

[Boxer, Aaron]

I am seeing another error when I try to render:



ERROR: In /Users/aaron/src/VTK/Rendering/VolumeOpenGL/vtkOpenGLRayCastImageDisplayHelper.cxx, line 554

vtkOpenGLRayCastImageDisplayHelper (0x10e3de0c0): failed after RenderTextureInternal 1 OpenGL errors detected

  0 : (1286) Invalid framebuffer operation


Any clues as to what could cause this?  I (not surprisingly) do not see any data displayed, just black pixels.


Thanks,

Aaron
