Hello everyone.

We have decided to phase out the Mixed Reality Forums over the next few months in favor of other ways to connect with us.

The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.

The plan between now and the beginning of May is to clean up old, unanswered questions that are no longer relevant. The forums will remain open and usable.

On May 1st we will be locking the forums to new posts and replies. They will remain available for another three months for the purposes of searching them, and then they will be closed altogether on August 1st.

So, where does that leave our awesome community to ask questions? Well, there are a few places we want to engage with you. For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality. If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers. And always feel free to hit us up on Twitter @MxdRealityDev.

occlusion and spatial understanding

I've used spatial understanding to place various objects on the floor including a square of grass underneath all of these objects. I have this working very well and the objects are placed precisely on the floor.

When I added occlusion with the Spatial Mapping Renderer, the spatial map that is on the floor the occulsion actually hides some of that grass on the floor because they are at the same level.

I've tried using the occlusion material on the spatial understanding custom mesh script, and end up with the same problem. I tried placing my holograms a little off the ground, but this causes its own set of problems.

Does anyone have a solution to this problem?

    I'm having a very similar issue, and would love it if someone could post something about best practices regarding rendering objects on the floor.

    The HoloLens' determined floor height is sometimes wrong, which is a little annoying if it's above the spatial mapping, but catastrophic if it's below. Basically you get objects being obscured by the spatial mapping triangles, making the holograms completely invisible.

  • This may be totally off the mark but what if you change the shader Renderqueue to something like overlay? just a thought or change the wireframe material shader to background

  • Good idea, I think that is a step in the right direction. I set the renderqueue to overlay for the square of grass that touchs the ground and it is no longer partially obscured by the occluded mesh on the floor. So that part is great. Unfortunately that also means that obstacles in the room like a piece of furniture allow the grass to show through. This leads me to think that the right thing to do would be to set the occlusion material shader to have a renderqueue of background, but to only do it for the part of the mesh that represents the floor. Does anyone know a way to do this?

  • Hey , @PoshPorcupine ,
    How did you manage to place the objects to spatial understanding results?
    I am using holotoolkit spatial understanding, but couldnt figure out how to replace small cubes with my objects

  • When I use the default "Occlusion" shadder on the spatial mapping, triangles through my holograms and it's awful. I deleted the line "Queue" = "Geometry-1" and it's ok. I think you can modify the queue to do what you want. I add lots UI, layers problem and in the end it's often a shader problem.
