Hi here again 😃

I’m trying to reproduce the procedural foliage tutorial (as this is quite a cool and advanced feature that we want to use for sure), and I run into the following issue:

> ComputeEastNorthUpToUnreal is not a member of ACesiumGeoreference FoliageCaptureActor.cpp line 176

I looked it up in **CesiumGeoreference.cpp** , and it looks like this was either changed not so long time ago into **ComputeEastSouthUpToUnreal** or to **ComputeEastNorthUpToEcef**

Would be interesting to understand why this was changed/deleted?

Any hint how this can be quickly fixed?

Cheers & Thanks

Claude

We removed `ComputeEastNorthUpToUnreal` because it was misnamed. It was an Unreal left-handed coordinate system, so it was actually East-South-Up not East-North-Up, despite the name. You should be able to use the new function in place of the old one, but let us know if you run into trouble.
