V-Ray License Server Error 200

I recently had a problem with the V-Ray license server on Windows returning and error -200 when I tried to render.

It turns out the error is because the VRL service wasn’t running and no amount of reinstall and reboots helped. 

Thanks to the help of friend I was able to resolve the issue by deleting a folder located at: C:\Program Files\Common Files\ChaosGroup

  1. Uninstall the License Server from the machine
  2. Then delete the folder C:\Program Files\Common Files\ChaosGroup
  3. Reboot the machine to reset the Windows Services
  4. Install the License server, it should ask for log in data now.
  5. Go rendering!

I spend hours on this so I am so happy to have friends that could help me on this, thanks Volker!

Associate .vrimg files with Photoshop

vrimg files are not associated with any program in Windows by default, they may be associated with the Chaos Group PD Player. Also it doesn’t appear that open with creates an association as expected therefore one may have to use the command line function ftype to achieve the desire association.

The general way to associate files using terminal commands is as follows:

  • Open cmd.exe with administrator rights (right-click on the shortcut to get this option)
  • Type ftype extfile="C:\Program Files (x86)\YourProgram.exe" "%1" where you replace the path with the executable of the program you want to use to open by default this extension (make sure to keep the "%1", this will get replaced dynamically to point to the file you’re double-clicking on) and optionally replace extfile with a name of your choice to describe the type of file you’re trying to open. Then press Enter.
  • Finally, type assoc .ext=extfile where you replace ext by the extension you are trying to associate and extfile with the name you chose above, then press Enter.

So for example to associate .vrimg files with Photoshop 2019 use the following command on a single line each in the Windows Administrator Command Prompt:

first:

ftype vrimg="C:\Program Files\Adobe\Adobe Photoshop CC 2019\Photoshop.exe" "%1"

then:

assoc .vrimg=vrimg

You should now see the .vrimg file have the Photoshop icon associated with them. It may be necessary to reboot or restart File Explorer before the associations show. Note Photoshop can not handle vrimg files natively it requires a third party plugin, I use ProEXR which is now free.

MODO – Morph Map Render

When creating a Morph map in MODO it is also necessary to add a Morph Influence for the Morph – after you create a Morph for the Mesh Item – for it to show in Renders. To do this Right Click on the Map under Morph Maps in the Vertex Map List and select add Influence. A Morph Influence will be added to the Item List with a small green icon. Now the morphs  should show in renders as well as the Viewport.

Thanks to William Vaughan for clearing this one up.
