Opacity broken for CTH, split views
Opacity is way broken for CTH datasets, split views. I believe there are multiple issues, so you will want to replicate exactly like this, at least once.
- remote server, 16 ranks, Linux, 5.5.0
- Edit/ Settings/ Render View/ changed Remote Render Threshold to 0. OK.
- Open Dave's small CTH dataset. 4 files, all around 100 MBytes each.
- Turn all variables on, although you only need the Material Volume Fractions (both of them). Apply.
- ExtractCTHParts. Material Volume Fraction 1. Apply. We now have a sphere.
- Select "Volume Data" in the pipeline browser.
- ExtractCTHParts. Material Volume Fraction 2. Apply. We now have a plate
- -Y
- Select the first ExtractCTHParts filter in the pipeline browser.
- Opacity == 0.5
Every thing looks fine at this point.
Note - spewage here about a bad k-d tree. Either this needs to be fixed, or turned off.

- Split view horizontal.
- Render View.
Notice that the sphere has disappeared. This is a bug. You also get the following:
