Enquiry about roadmap of mesh streaming

Hi, here dev based on staticmash src code base and met a bunch of //TODO under static mesh serialization( inline or not inline). However, tasting several cases and usages(editor or cook) of mesh streaming seems no obvious issues and problems. The feature is tag with experiment in Cvar name whichs has been mentioned several times in the community which also add confusement related to my current issue.

Another issue I met is the following customVersion is not working(specifically not declared before using)[Image Removed]

Hello, r.MeshStreaming was incorrectly tagged with “experimental” but that was removed in CL#36109421 (9bf7b4) which is in UE 5.5 and we have it enabled in several projects, it should be fine to enable.

I’m not sure why FUE5ReleaseStreamObjectVersion::GUID working, that code has been in the engine for years and is used in many places in the engine, can you provide more information about the error and how you worked around it?

Hope this helps!

versions (Add a new vesion in my case) always get the latest one and cannot get the correct version of buffer when it serialized

Thanks for the additional information - I haven’t run into this particular issue but if you want us to look into it I’d be happy to do that if you can provide steps to reproduce the issue in an unmodified version of the engine - or in a sample project.

Good to know!

For the object version, for the screenshot I attached, observation is versions (Add a new vesion in my case) always get the latest one and cannot get the correct version of buffer when it serialized. I am not that handy to check how it works in latest UE and we are on custom build engine. However I believe code related to this haven’t been modified. During my several tests mentioned above, StaticLODResource serializes itself and holds its life in DDC only, which make obejct version unnecessary because clearing ddc can fix my case, If I understand correctly for how it works ATM.

You are welcome but I do not require to further investigation on the object verison now. I found another issue related to non-vsm shadow cache during test which I create another report here with a demo and hope you are intereted to have a look. [Content removed]

And this issue can be closed ​and I don’t have any further enquiries on this topic currently as well.

Cheers,
