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.
Currently, on all operational systems the vrmesh_viewer.exe is located in V-Ray's folder (where the V-Ray files are extracted) > appsdk > bin.
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.
