Hi Gopal,

You can do this in HyperCrash.

From Mesh editing option select the Rigid body option, click on Select All >> click Review. Now change the Mass option to zero so that for all the rigid bodies selected this change will be reflected.

HI,

As total number of rbodies is greater than 10k I am not able to see them in panel view. I have to take view one by one for this.

Hi Gopal,

Luckily I have a script for this. If you run this script it will update all the rigid bodies with 0 mass.
