Hello,

I don't know if i can explain that in english …

I would like to make wire simulation of a mesh . But I wan't to use a kind of copy system to add copy of the mesh to the sim.
Jus look to hip file. You should understand better what I want to do.

Thanks for your help.

Using SOP Solver to merge in the geometry is the correct way. First, the source geometry (Copy SOP) needs to be slightly modified to only contain the new geometry that needs to be added to the simulation. I just did this by making the lifetime of the particle to be 1 frame.

Next, before merging the geometry into the simulation, you'd have to initialize the restP attribute. The solver uses the restP attribute. If the source geometry doesn't have the attribute, it'll be initialized to 0 during the merge, and the solver gets confused. This step is a bit unintuitive. We've created a RFE to improve on this.

Take a look at the attached .hip file.
