Here is a new version of the VRMesh Export ZPlugin.
The main addition is actual functionality for the VRMesh Export > Export Highest SubDiv switch. Before it did nothing, now it automatically sets the subdivision level of each exported subtool to the highest level. When the export is finished it returns each subtool to its previous subdivision level. Useful if you have many, many subtools (VRMesh Export has a limit of 400 subtools, but I think that is ok;))
The second addition is VRMesh Export > Show Command Execution, which is helpful when troubleshooting errors or to determine the effect, timewise, of the various ply2vrmesh settings. On OS X it launches the shell script in Terminal.app and on Windows it pauses the batch script execution before it exits.
If you run into any problems with generating the .vrmesh files then please run the ZPlugin again with VRMesh Export > Show Command Execution enabled and post the output here.
It appears that some arguments are not supported on older versions of ply2vrmesh. Please make sure you are using a recent version. The ply2vrmesh executable displays the build date when run. When writing the ZPlugin I used ply2vrmesh builds from June 12 2015 on OS X and June 16 2015 on Windows.
Here is the ZPlugin:
How to Install:
Extract the VRMeshExport.zip file and copy the VRMeshExport.zsc file and the VRMeshExportData folder to the ZStartup/ZPlugs and ZStartup/Zplugs64 folders of your ZBrush installation.
Locate Chaos Group’s ply2vrmesh executable (ply2vrmesh.exe on Windows and ply2vrmesh on OS X). Copy and paste it into your ZStartup/ZPlugs/VRMeshExportData/ExportedFiles and ZStartup/ZPlugs64/VRMeshExportData/ExportedFiles.
Restart ZBrush and you are good to go.
How to Use:
The ZPlugin is located in ZPlugin > VRMesh Export.
Select a tool with polymesh and/or parametric primitives (ZSpheres are ignored). Adjust settings and export to a single or multiple .vrmesh files (OS X only supports multiple files). Manually open the .vrmesh files in your DCC app of choice. The exported files are located in ZStartup/ZPlugs/VRMeshExport/VRMeshExportData/Exportedfiles or ZStartup/ZPlugs64/VRMeshExport/VRMeshExportData/Exportedfiles, depending on which version of ZBrush you use.
