What module needs imported for occlusion related Mesh properties to be available?
Specifically, properties such as ‘occlusionQueryAlgorithmType’ , ‘occlusionType’ , and ‘isOccluded’ don’t appear on Mesh type in my local dev, where I use Babylon modules.
Examples in documentation:
Hey there, welcome to the forum. 
Here’s the import statement you need for those properties. There’s a list in the documentation at the end of the FAQ that tells which modules are needed to enable various features. But @RaananW it looks like there’s a discrepancy where the doc says “engine.occlusionQuery” but really it’s “engine.query”.
import "@babylonjs/core/Engines/Extensions/engine.query";
Thank you very much Blake.
Will solve this first thing tomorrow. Thanks for reporting!
This was updated. thanks again
