Hello,

Here is my issue : I don't see the colors bars in AR. Maybe cause this one are in sub BP.

Here you can see the sub BP :

I try to add tag in blueprint in event begin play but without result :

Do you know a solution for this issue ?

Thanks

JD

I found documentation here : https://aximmetry.com/learn/virtual-production-workflow/preparation-of-the-production-environment-phase-i/ar-production/aximmetry-de-scene-setup-ar/#dynamically-spawned-models-and-actorshttps://aximmetry.com/learn/virtual-production-workflow/preparation-of-the-production-environment-phase-i/ar-production/aximmetry-de-scene-setup-ar/#dynamically-spawned-models-and-actors

I'm in mode Tracked + AR

The variable is this one :

You need to setup the camera in blueprint like this :

Unfortunately, I cannot find the "Update ARObjects" node. If I look in the blueprint of the Aximmetry camera, here is what I find on Update:

But, whith tracked+AR, search for initialize AR

For me, it stay one issue : the edge of the AR is white :

Do you know how to remove this white edge ?

Thanks

JD

Hi JD,

Great job finding the Initialize AR function.

Regarding the white edge, I'm not entirely sure what could be causing it.

Do you see the white edge in the AR Out video?

You can use a Blender and Solid Color module to put a black background behind it.

It could be a material issue. Are you using opaque materials on those AR objects?

Check to see if there is fog or sky on your map that might be causing this. You can find more information on that here: https://aximmetry.com/learn/virtual-production-workflow/preparation-of-the-production-environment-phase-i/ar-production/aximmetry-de-scene-setup-ar/#fog

Also, it might be an issue with your Project Settings. You can share your Project Settings with us by sharing the DefaultEngine.ini file, which is located in the config folder of your project's root folder.

Warmest regards,

I had fog and sky and I delete it but I still have white edge. I figure out that the translucent material are white and not translucent. 

Here is my DefaultEngine.ini :

Hi,

I found that changing the AR's ADJUSTER's Sharpen parameter from 0 creates a very similar artifact. So make sure it is set to 0:

Otherwise, I couldn't recreate the issue with your Project Settings. If those objects use translucent material, then try changing the material to Opaque and see if that fixes the issue:

If changing to Opaque does fix it, share the material with us so we can investigate how it could be causing this issue.

Warmest regards,

Ok, I confirm, the problem is whith fog, the skylight to create this white edge. 

Hi,

Unfortunately, there is not much you can do about this other than removing the fog when using TrackedCam + AR compound.
However, if you render the AR on a separate machine, you can have a separate level for AR, as you would use separate TrackedCam and AR compounds. You can find more information here on how to combine it with separate machines:  https://aximmetry.com/learn/virtual-production-workflow/preparation-of-the-production-environment-phase-i/led-wall-production/combine-different-productions-in-separate-machines/

Alternatively, you could use Aximmetry to render AR, which would eliminate the need for an additional computer. More information on Aximmetry-rendered AR can be found here:: https://aximmetry.com/learn/virtual-production-workflow/preparation-of-the-production-environment-phase-i/ar-production/aximmetry-se-scene-setup-ar/ 

Warmest regards,
