Question Asset model

For Enscape version 4.10, in the Chaos Cosmos Asset section, the old asset models that we have customized - can we still use them in the new version?
If we upgrade to the latest version and use the latest models, and another person doesn’t have the latest version, can they open and use the same file in a lower/older version?

Great question. I’m also worried about problems with custom assets. I’ve created 3,000 models and can render beautiful rooms in 30 minutes.
