Hi haniel1107 Could you please give us some additional information so we can assist you:

1. Does it happen with every scene? Even a new, simple one?
2. Please, share with us the .bugreport file and the .dmp file so we can investigate them. You can see how to generate the .dmp file here: https://docs.chaos.com/display/VC4D/Creating+Dump+Files
4. Share a videorecording of the crash so we can observe the exact moment.

Thank you viktor_angelov. I've sent you a PM.
I tried a new scene with just a sphere and a decal from cosmo, this worked..

Thank you, haniel1107 I have shared the files with the team and we will investigate them further.

Seems like a big scene you are working with. Have you tried deleting the Decal to see if the crash will appear again?

Also, if you could share the scene with us so we can take a look that would be great.

Hello viktor_angelov, yes without decal or deactivated everything is fine. Could you try without a scene first to find something out? As I would need to ask the client for the scene..
Thank you for your help!

[viktor_angelov]

It works as expected on my side. Could you please share a scene with me that I can reproduce it with?

[haniel1107]

Hello viktor_angelov, I've reduced the scene as much as possible and sent to you a PM with a link. I think the car inside the scene causes the decal crash, but no idea why...
Thanks a lot for your help!

[viktor_angelov]

Thank you haniel1107 I have shared the scene with our developers and they are looking into it.

Hi viktor_angelov, thank you, I hope they find the reason … have e good day

[haniel1107]

Hello viktor_angelov, may I add something, I played around with the same reduced file, which I 've sent to you yesterday. There are 8 objects remaining with a vray geometry tag, for subdivion reason only. When I delete those tags (or switch off the objects), it doesn't crash with decal.
Can you confirm, this could be the reason? In my not reduced project the car has a lot of these tags. The original file is a Vray maya file which exchanged through the vray eporter. So these tags came from maya or from the exporter...

If this doesn't make sense, please ignore..

Hey haniel1107, indeed the geometry tags with the subdivision lead to the crash (when there is also a Decal in the scene). We are investigating a potential fix for this problem, but until it makes it to the public builds, you can workaround the issue by disabling the subdivisions from the geometry tags - displacement should be safe to use from the tags.

Hi deyan.hadzhiev, super thank you!
