Stereo Billboard for VR

anonymous_user_fa450e60 · March 4, 2016, 8:38pm

Hi, i want to create a billboard with a movie in stereo.

I want to show a different movie for each eye in the VR Preview.

I think that it’s possible using a Bluprint, material billboard and with the screenposition, but i don’t know more…

Thanks!!

I want to do the same thing using captured camera inputs.
Here’s the material you need for “side by side” stereo.
The movie would have to be rendered as one texture in “side by side” mode.

Hi,

ScreenPosition seems not to work with HTC Vive.
Can anyone confirm this? Any ideas?

Hello,

if you want to have dedicated access to the rendered images for left and right eye using the “ScreenPosition” node in Unreal Engine 4.x you must turn off “Project Settings → Rendering → VR → Instance Stereo”.

At least I can confirm this with HTC Vive and Unreal Engine 4.14.3.
“Instanced Stereo” was introduced in Unreal Engine 4.11 and increases the performance tremendously.

Any ideas how to avoid to turn off “Instanced Stereo” are welcomed.

Best,

Hello,

you can use ‘ResolvedView.StereoPassIndex’ in a Custom shader.
This works with “Instanced Stereo”, too.
