This page describes the V-Ray Mesh Viewer and its usage.
The V-Ray Mesh Viewer is a simple tool that previews V-Ray mesh and alembic files. It can display both static and animated meshes.
After the tool is loaded, the tool will ask for the .vrmesh or .abc file to preview. Click Open to view the mesh.
Navigate around the mesh by holding Alt and then using the Left mouse button to Rotate, the Middle mouse button to Pan and the Right mouse button to Zoom.
The V-Ray Mesh Viewer is installed along with V-Ray for Maya and can be found in C:\Program Files\Chaos Group\V-Ray\Maya 20xx for x64\bin (where xx is the end of the year version number).
