Bullet - Increasing Glue Strengths lower Impacts?

Recommended Posts

Hi,

I did a small experiment to understand the relationship between impacts generated on glue constraints and constraints strength. Below are two results:

Experiment 1 : Glue strength = 20e9 --> max impacts on constraints = 2,879

Experiment 2: Glue strength = 20e1 --> max impacts on constraints = 286,801.8

My question: why impacts are function of Glue strength? As seen above, when I increase Glue Strength I get lower impacts? Should not impact be function of object mass, speed for example and not of glue strength?

PS Attached is a simple hip file for the test...

Thanks

Did you ever learn more about this?  I'm also trying to wrap my head around how exactly glue/impacts/propagationiterates play with each other.

They are not. You are comparing 2 completely different things - in one case constraints are starting to break - which means more free pieces to collide with = more impacts.

Try the same experiment without breaking a single constraint - for example 20e5 vs 20e9. Do u see any difference?
