As shown in the image, I would expect the last too bools to be True but they are False. Am I doing this wrong, missunderstanding how to use .ValueIsBlocked?

Thanks Sue

Hi @Suekieza , we could definitely benefit from [better documentation on ValueIsBlocked()](https://openusd.org/release/api/class_usd_resolve_info.html#a47c6e4143df49a32b7a459f06d0483a3), but the fact that it does **not** take a UsdTimeCode parameter hints that it is limited to telling you only whether the attribute is **fully** blocked in a non-time-varying way (i.e. a SdfValueBlock has been authored to the strongest spec’s `default` and no timeSamples or spline have been authored to it.

Sorry - it’s pretty confusing, but please feel free to file an Issue for clarification. We could, potentially, also add a TimeCode-accepting overload that _could_ answer the question… the only thing is that that query will be quite a bit slower, especialy if the attribute is being fed by Value Clips, whereas the current query is just returning a cached bit.
