Bullet Collision problem

Recommended Posts

Hey all,

I'm trying to pack primitives for the bullet solver that include baked ODE data for compound collisions proxies. The red nodes are a method that is currently not working but is ideal for setting up constraints. Attached below is a example file with identical inputs to identical simulations with one key difference. 

In green I am baking ODE data inside of a for loop and packing each object individually the ODE data is maintained and the simulation works.

In red I am copying the name data to the ODE baked primitives, and instead pack each piece using the name attribute OUTSIDE The forloop. In this case the ODE data is lost.

There are two nulls on the side where I've broken out a single identical piece to show the ODE data difference for each means of processing the pieces.Does anyone know why the pack using name would remove the ODE data from the piece?
