Augmented reality template - reveal AR object from the real world floor

Content Creation Augmented Reality Unreal

 

I want to create an AR project where AR elements are revealed from the real world floor (for example slowly moving up from the floor level). I tried using custom materials that work as masks but I doesnt work. I understand that I need a plane on the real world ground level with custom material which will cut off everything below him but I don't know how to create it. 

Is it possible to do this in Aximetry DE?


Example of concept - logotypes in 1:29 slide from the floor (I know that is done in virtual studio not in AR but it shows what results im looking for) https://www.youtube.com/watch?v=QyhveUyG0TA&t=39s

Yeah I read this tutorial many times and it doesn't answer my question. 

Maybe it will be easier to demonstrate my goal visually.


Like in this gif I want to reveal an AR object from a real world floor level (virtual floor is added only for demonstration purposes).    


When i delete virtual floor and move my object in Aximetry they only move up and down and don’t disappear under floor (gif bellow) what is understandable because aximetry dont’ know where is the floor level - so i understand I must create some plane on real world floor level with custom material that will mask off everything below him and shows everything above him. Any ideas on how to do that?

A bit of a workaround, but couldn’t you just use the Masker module in Aximmetry to create a mask the AR object at the floor plane? This assumes no other AR elements would be visible in front of the object that should disappear into the floor.

Unfortunately is not that working for us and I still looking for solutions I think the easiest way will be to this in Unreal level.

Hi,

Yes, probably the most universal solution for this is to make a custom material for the object (chair).

Here is an example of such a Masked material:

In this material, you will be able to control the height of the ground by the Ground Level parameter.

Here is how it looks:

Also, there is a dedicated AR Unreal Camera (TrackedCam_AR_Unreal_Prev_3-Cam.xcomp):
With this Camera, for example, you can easily make shadow's on the non-existent virtual floor using in Unreal the Aximmetry_TrackedCam_AR\Blueprints\Aximmetry_Shadow_Catcher:

Warmest regards,
