Problem Preview material vray 7

[visualtracing__]

Hi,
I've been having preview issues with materials for a while now. I've also installed the latest build (V-Ray 7 for Cinema 4D, Hotfix 1 (v7.00.01 from Feb 11 2025) but the problem remains.
this does it with standard vray materials while with noded materials it works fine

I'm on windows 10 and Cinema 4d 2025.1.2

thanks

Hi visualtracing__ There are couple of things for you to try.

1. Check the server if the licenses are correctly connected: Local Host License

2. Check if you have set the Render Engine to V-Ray from the Render Settings


3. Check if the Render > Node Space is set to V-Ray


4. Go to Materials > Render Materials and see if anything changes


Finally, it might be an incorrect installation. Did this issue appeared out of nowhere or after a certain change you have done?
Did it start with V-Ray 7 or you have had it with V-Ray 6 as well?

Please, let me know how it goes.

Hi, thanks for your support.

I had this problem since version 6. I checked everything you asked me but every now and then I always have some shader that does not display the preview,

The same thing happens to me too, very annoying, it happens to me since I installed the latest version of Cinema 4D.

this issue has persisted since 5, there are many posts about it. I was hoping it would finally be resolved, but I guess we've lived with it for this long.
