Can't seem to reproduce that one. The opacity setting is quite similar with
and without ospray for the test cases I've got. Can you provide more
information and data to help me reproduce it.

Likewise, I can't seem to reproduce that either. I opened can.ex2,
extracted the can block, extracted surface, generated normals, stepped
through time. All worked OK.

This one I can. This will fix when merged to master.

[Paraview] OSPRay rendering issue: 1) opacity 2) moving body rendering 3) ospray , shadow option

[SeongMo Yeon]

I am using ParaView 5.1.2.

today, what I found with OSPRay is three things.

1) Once OSPRay is enabled, opacity is not applied. is it normal or 
ParaView bug?


2) I have CFD results of sloshing tank which is moving around. To 
visualize tank boundary, extrack block filter and generate surface 
normal filter are applied to the field. Since sloshing tank problem is 
unsteady, I proceeded the time and found that two tanks are shown: first 
one is the previous time step one and the other is the current time step 
one. It looks like ParaView bug.


3) I have found that after OSPRay is enabled with shadow option, 
ParaView crashes if I turn off shadow option before OSPRay is turned 
off. this behavior looks like bug.



Regards.

Most likely you are running into this bug:
https://gitlab.kitware.com/paraview/paraview/issues/16919

Try applying the generate surface normals filter and see if you get colors
then. If you can, please send me a screen capture and the data if
permissible to help track it down.

[Paraview] OSPRay rendering issue

[Seong Mo Yeon]

I have paraview 5.1.2 installed with ospray enabled.Ospray version is 1.1.0 
prebuilt version. Paraview setting is as follows:LOD threshold as 0 LOD 
resolution as 0.5 Use outline for LOD rendering as checked Remote render 
threshold as 0 Outline threshold as 10 Use offscreen rendering for screenshots 
as checked  The issue is that the surface extracted by extract block is not 
rendered properly but colored with black regardless of representation option. 
Other effects by e.g., stream tracer is rendered nicely. Is this behavior is 
due to paraview bug or my paraview setting?  Thanks
