### ✨ Overview & highlights

**Fixes to `.rrd` Chunk handling.**

We revised our Chunk slicing logic to prevent `.rrd` files ballooning in sizes. This also fixes the problem of broken `.rrd` files that contain tensors.

**Collada (`.dae`) mesh support.**

This patch adds native support for Collada (`.dae`) meshes, a common format used with URDF files. You can now load URDFs that reference `.dae` assets without manual mesh conversion!
