Dear Vapor community,  
I am trying to visualize a WRF-Fire version 4.2 results using Vapor 3.2. But when I try to create a barb renderer or some other renderers, Vapor hangs and I have to force quit it. Could you please help me what is the problem?  
I am using 16” Macbook Pro running Catalina and I am trying to visualize an idealized WRF-Fire simulation  
Thank!

Hi Kasrash, could you please open [a ticket on our github issues page](https://github.com/NCAR/VAPOR/issues/new?assignees=&labels=Bug&template=bug_report.md&title=)?

If not, I can help you here too. But this kind of thing is easier for us to track on github.

Can you also provide a sample file, and the steps you execute to reproduce the hang?
