Title: Converting Vray Materials & Missing Mtl
Post by: Otuama on 2023-09-07, 16:40:23
Hi all

We've just installed Max 24 & Corona 10. We're having 'Missing Mtl' issues on Vray objects.

Corona Converter also can't convert them. This is obviously because we don't have Vray installed.

We used to have a Vray license but don't anymore. 

When updating the office I didn't bother to install Vray.

Should I have? 

If so, do we need to sign into it or anything?  In the past I'd put our account details in.

Any tips?

Thanks

Hi,

you can go here: https://download.chaos.com/

A simple sign in and download the V-Ray setup for your 3ds Max version. You don't need to activate it, just having it installed will solve your issue.

Let me know if you need any other help.

Hi, thanks for the reply.

This has been done but 5 systems are having issues when rendering an animation.

08/09/2023 12:06:58: 08/09/2023 12:06:55;  Error rendering frame 0: [V-Ray] Could not read V-Ray environment variable "VRAY_FOR_3DSMAX2024_MAIN". Please re-install

I've reinstalled vray on these systems & have opened max (in case it needed to be opened to update a file or something)

This hasn't worked.

I've uninstalled vray on 2 systems and it's now working on those.

I can uninstall vray on the other 3 systems for weekend rendering but does anyone have and idea why?

Thanks

restart the computer after installing vray to initialize the environment variable.

That worked FFS :D

Weird that I didn't need to restart 6 systems and they worked.

Many thanks
