Greetings @Knuthnads

In regards to the error that you’re getting and the importing of the larger heightmap, I’d recommend reading a reply on a similar thread [here](https://forums.unrealengine.com/t/assertion-failed-texturedesc-extent-x-int32-getmax2dtexturedimension/752484/2). I hope this helps answer the question!
