This page provides information about the Opacity Cutout tool in V-Ray for Maya.

 

Overview

The Opacity Cutout tool converts low-poly opacity mapped objects to actual geometry cutouts. Actual geometry renders faster than opacity mapped objects, but increases both the poly-count and scene file size.

The Opacity Cutout tool preserves instances, as well as transformation and deformation. This tool is ideal for converting broad-leaved trees or other similar types of vegetation for faster rendering, but can be generally used for any type of object.

Currently, only Maya meshes are supported. Opacity JPG and PNG texture files are supported.

When converting, use meshes with one material for all faces. Objects with per-face materials do not work for conversion.
