When I drag an object into my scene and the object is merged/converted as a proxy on the fly, the set Object ID is remembered. But when I want to export a whole directory with objects to VRay proxies, all object IDs (of the proxies) are set to zero. Is this a bug or a limitation?

Just the other day, I was testing bulk conversion in proxy.
It works great in max 2025. I will try it in an earlier version of max.
But it should work because the code is the same.
I’ll check for this, thanks for your feedback

Thanks for checking.

I just double-checked:
When I drag an object with ID=107 into the viewport with Merge As Proxy and Use Existing Proxy File disabled, the object has ID=107 after placement.
When I drag an object with ID=107 into the viewport with Merge As Proxy enabled and Use Existing Proxy File disabled, the object also has ID-107 after placement.
When I then drag the same object with ID=107 into the viewport with Merge As Proxy AND Use Existing Proxy File enabled (while there now is a proxy file), the object has ID=0 after placement.

The same is happening when mass exporting objects to proxies and then load them with both options enabled.

As far as I know, it seems like a limitation since with dragging you only drag the VRMESH and afterwards apply the MAT-file and both have no info about object ID. The only way to know that is by either also openeing the MAX-file or load the proxy from a MAX-file. So I wonder if this is working in Max2025.

Batch exporting works well in max 2018 also

When I then drag the same object with ID=107 into the viewport with Merge As Proxy AND Use Existing Proxy File enabled (while there now is a proxy file), the object has ID=0 after placement.

This means what existing proxy don’t store ID.
And wait… Do you mean this ID? If, yes, it is impossible to store it in proxy.


Only these, material IDs are stored

Yes, I mean the Object-ID. So if I want to use this with proxies, the only way is to load proxies from a Max-file, and not with a VRMesh in combination with a MAT-file.

Thanks for your assistence.

Try to use material ID for effects instead of object ID.
Material IDs are stored with the materials.
