| File Type | Extension | Purpose | |-----------|-----------|---------| | Proxy mesh | .vrmesh | The actual geometry data | | Material library | .mat or images (.jpg, .png, .tif) | Textures for bark, leaves, alpha maps | | Preview scene | .max | A simple scene showing how to use the proxy | | Opacity maps | .png or .tif with alpha | For leaf cutouts (crucial for realistic trees) |

Before we dive into the downloads, a quick refresher. A V-Ray Proxy ( .vrmesh file) is an external file that lives on your hard drive. Inside 3ds Max, you see a low-poly placeholder (a bounding box or a simple cross-section). When you hit render, V-Ray reaches out to the hard drive, reads the complex geometry, and renders the full detail.

Both platforms allow you to filter by "Free." While not everything is proxy-ready, you can download low-poly or medium-poly trees and convert them yourself.
