# Anatomy Rig Tissue This node converts your character's skin to a tet mesh and collides it with the cached muscle simulation. {% hint style="info" %} We give the option of placing a Vellum Solver after this node however it is not necessary. Simulating with a Vellum Solver will not offer better results in every case, it may help stop stretching in certain areas. We disable it by default for creation. {% endhint %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
