Sorry but V-Ray for Blender doesn't seem to be production ready

As much as I love the look of V-Ray, I am going to uninstall it today and cancel my subscription… I don’t have time to spend debugging and writing forums posts about issues I encounter, I am using this on an actual project and I just wasted 2 days on weird issues.

One of them was that for some reason was exposure in one of my scenes was different in IPR than in final rendering. I tracked it down to some V-Ray sphere lights in my scene, after I deleted them, the IPR would be the same as final Render. Hiding the lights or setting their intensity to 0 would not stop them from affecting the exposure.

Second issue came when I was trying to set my main objects as not visible to camera, after waiting for 10 minutes for blender to go through all of the objects and disable the checkbox, my whole scene got corrupted or something, and I cannot render in it anymore, it just turns black. I tried deleting the objects and reimporting them, but it still doesn’t work.

Sometimes rendering doesn’t work properly, even though I switch from Bucket to Progressive, it would still render with bucket, and not take into considerations my max samples, and just render noisy image.

Frame buffer is also buggy, sometimes elements like Denoiser or Lens effects turn of by themselves between renders.

Going into IPR takes a long time, even if I hide all but 1 object in my scene, it still takes 20-30s to load the render view, seems like it just loads all of the geometry into memory or something, making it painful to iterate.

Hi hulpesergiu,

Thanks a lot for sharing this, and I’m really sorry you’ve had such a rough experience.

One of the issues mentioned is already logged in our bugtracker. For the rest of the problems, we’d like to see what’s going on. If you’re open to it, you can either share your scene here on the forum or send it to us via a support ticket, and we’ll go through everything you described. It would also help us a lot if you let us know which versions of Blender and V-Ray for Blender you are using.

Unfortunately I cannot share the full scene as it contains confidential customer data, if you want I can share, the empty scene, but I am not sure how much that can help. Also the scene I previously shared via a shared download link has expired without being downloaded, so I am not sure if anyone is actually looking at these files.

Hi,

If you prefer, you can submit a support request through our ticketing system instead of sharing the scene on the forum. Files attached to a ticket are not publicly visible and are accessed only by our support team. Any scene provided to us is used strictly for troubleshooting purposes and only to investigate the reported issue.

If you still have concerns about sharing the full scene, a good alternative would be to remove or replace only the confidential parts (e.g., customer-specific assets, branding, sensitive geometry) while keeping the rest of the setup intact. Just make sure that the issue is still reproducible in the modified scene before sharing it, as that’s crucial for our investigation.​

Regarding the scene you previously shared, please share the ticket number, so I can check its current status. ​
