can't open vray material editor

Can’t edit materials or open Vray material editor. Geting this pop up window: “Unable to initialize - no license or improper configuration”. It started after vray updated to 3.7 version.

I had a similar problem. Everything worked except for the “Assets Browser” tab. The problem was solved after installing the latest version 3.70.02. The forum will be a link. Find, download and install.

Hi, Marek. Thank you for your answer. I searched forum and find you post about this issue. Problem was solved in private message from Ana Lyubenova - i assume link for latest version 3.70.02 also was sent to you in PM?? i couldn’t find one there.

Hello I have the same problem, did you solved it?

Hi,
Not yet but we are working to include it in a hotfix.
Until then, the workaround is to start vrmateditor.exe from its folder location in C:\Program Files\Chaos Group\V-Ray for Revit\vrmateditor

Best,
Ana

Hi everyone,
a Colleque of mine has the same problem using the mat-editor… Others dont have any problems. So is the Hotfix allready available ? Or will the version 3.70.02 fix the problem allready ?

Hi Tom,

The hotfix has been available for a month or so now. Here is a link to the download page. Version is 3.70.03.
Update and let us know if the problem persists on your colleague’s machine.

Best,
Ana

Hi Ana,

We are on the latest build (3.70.03) + Revit 2019 - fresh install.

Same problem. Can you please advise how to fix it?

Please, check if your antivirus software is blocking the vrmateditor.exe.

Build 3.70.04 has this same problem. Turning off antivirus doesn’t help.
Double-click a .vrmat files does open the vrmateditor though.

Hi mjverbeek,

This will be fixed in the upcoming version. Please, use the workaround.
