A transparent occluder can be achieved in Unity via the VR/SpatialMapping/Occlusion shader or in three.js like here javascript - three.js transparent object occlusion - Stack Overflow which is very useful for AR solutions. Is there already a way to export this behavior in Needle exporter, or will I …

Hi, the shadowcatcher has an Occluder mode [image]

Yep, that is possible, good idea to ship it in core

It’s similar to the ShadowCatcher material, you can check out this sample for a starting point: [image.png]

Basically for now you’d make a TS component and add it to objects you want to block, and the component changes the shader directly on the three side.

ok, thx for the swift reply :slightly_smiling_face: by user 474974683163394049

Hey, is such a transparent occluder material included in the core package meanwhile, or do we have to build it on our own?

Is there already a solution for a transparent occluder material?

Great, thanks for your feedback. I can confirm that it’s working.
