Hi,
I am using Paraview 5.9.1.
I have an axisymmetric data set, on which I use the rotational extrusion filter.
In this filter, I enable the ray-tracing. Until this point everything works.
But when I use a HDR image as background, I get the following error messages:
( 73.427s) [pvbatch ]vtkOpenGLFramebufferObj:1376 ERR| vtkOpenGLFramebufferObject (0x6f0df9d0): The framebuffer is incomplete : FRAMEBUFFER_INCOMPLETE_ATTACHMENT
( 91.228s) [pvbatch ]vtkOpenGLFramebufferObj:456 ERR| vtkOpenGLFramebufferObject (0x728c84f0): Frame buffer object was not initialized correctly.
and a lot of this output:
Current framebuffer is bind to framebuffer object 38

there are 8 draw buffers.
draw buffer[0]=GL_COLOR_ATTACHMENT0
draw buffer[1]=GL_COLOR_ATTACHMENT1
draw buffer[2]=GL_COLOR_ATTACHMENT2
draw buffer[3]=GL_COLOR_ATTACHMENT3
draw buffer[4]=GL_COLOR_ATTACHMENT4
draw buffer[5]=GL_COLOR_ATTACHMENT5
draw buffer[6]=GL_NONE
draw buffer[7]=GL_NONE
read buffer=GL_COLOR_ATTACHMENT0
In spite of this messages, the image is rendered, but a lot RAM is used, which eventually leads to an abortion of the program.
Please find attached the python files I use.
The first one is for the pvbatch command, the second one can be loaded as state into the GUI.
A data set can be downloaded with Link - LRZ Sync+Share.
The HDR image can be downloaded via HDRI: Lakeside | HDRI Haven. I use the 16k version.
