How can we increase the contact tolerance distance between cloth and actor?

When simulating cloth on NvCloth the distance between cloth and actor is really small so if
I print the frame in vtu. It appears to look like cloth penetrates the actor.

Is there a way to increase the contact tolerance distance between cloth and actor.

The easiest way to do that is to have separate meshes for simulation and rendering, and inflate the simulation mesh used for collision detection by the amount of tolerance you want between the cloth and the other object.

A easy and cheap way to do that is to calculate the smoothed normal for each vertex on the collision mesh, then move all vertices along their normal by the tolerance distance.

Thank you mtamis. Thats exactly what I did and works perfectly.
