Same problem, looking for a solution to make the virtual screen partly translucent in AR template. Furthermore is there any method to pass a key and fill to a virtual screen to make a proper mask in AR template?

Hi,

To use the virtual screen with alpha, you need to change the material to be Translucent instead of Opaque.
So open the material that you are using for the virtual screen, change the Blend Mode to Translucent and connect the alpha (A) from the texture to the material's Opacity:

Hi KGH.EC,

Yes, you can pass any video to the virtual screen. However, I am not certain why do you want to pass key and fill and what kind of key and fill.
Can you describe a bit what do you want to achieve in your project?

Warmest regards,

Hello 

My goal is to create a virtual screen and use it in an AR tracked template. I want to replicate the use of a real life led volume screen (smth like in the screen below - concert shot) but with a tracked virtual screen. 

Also I want to have a fully working alpha layer on screen so we can see the real background if needed. Source video input to the virtual screen will be added from the Resolume Arena (as fill and key) because it's very easy to create nice motion graphics in Resolume. 

Currently I have figure out that the easiest way to do this is via aximmetry native render system (I tried to this with rendering AR elements in Unreal AR template but the alpha layer does not work) 

Now I project the fill and key to the shader and next to the box shape and It works fine. My only problem is that I can't move the box via scene node. I added a screen with my node scheme and final result below - looks like crap but it's only for proof of concept (blur module is added only for privacy reasons). 

Can you help me with moving the box in my scene? Also any hints how to do this better will be nice. 

Regards 

Hi KGH.EC,

You can not move the Box with the Scene Node cause you also connected the Camera to it and the TrackedCam_AR to it. So you are moving everything with it:

To make it look better, first I would suggest adding some lighting modules. (at least the Directional Light module)
Then you could add the Render_General compound (located at: Common_Studio\Compounds\Render\). This compound has a few post-process modules inside it that you can enable.
These tutorials can help you greatly on how to make scenes and 3d objects in Aximmetry look better: https://aximmetry.com/learn/tutorials/a-complete-studio-scene/introduction-to-complete-studio-scene/

Also, if you want to do it unreal. You can still use the video Alpha Merger in Aximmetry and connect the video to the Unreal compound after video is mixed. You don't have to mix the fill and key in Unreal. You can even use Aximmetry's render objects while for example, you have an Unreal Rendered background.

Warmest regards,
