Vellum Constraint not creating mass attribute in DOPS

[codedad]

Hi -

I was creating a simple vellum DOPS network from the shelf tool, and wanted to eliminate the extra SOPS import and do all my work in DOPS using dynamic vellum constraints.  However, I noticed when I was doing this that gravity was not working.   I am using Set Uniform to Mass = 1.0. 

 

However, when looking in the DOPS spreadsheet, it was still zero.



I was able to fix it by adding a Geometry Wrangle

But this seems like I shouldn't need to do this?  Is this a bug or am I misunderstanding how the Mass option works?

Thanks for your help,
Doug
