Volume rendering non first block fails
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
You can only volume render the first block of a multi-block dataset. This is a bug, and desperately needs to be fixed.
- Linux, master, local server.
- Open can.exo. All variables on. Turn off the first block (leaving the second block, the plate, turned on). Apply.
- Volume render.
<> You will see lots of warnings, and nothing gets volume rendered. Without tricks, this makes volume rendering non first blocks impossible.
