Temporary workaround for Barrel Distortion bug

5 replies
2650 views

There is a bug at the moment where built/cooked UDK demos/games are released, they do not display the Barrel Distortion pixel shader even when using the HMDWARP ON command.

To work around this, go to
UDK\RiftCoaster\UDKGame\Config\UDKSystemSettings.ini

set

DepthOfField=True

Somehow when DepthOfField is false, it completely shuts down the Barrel Distortion pixel shader.

OK. I can confirm this does fix the issue.

What appears to be happening is that if certain post-process effects are turned off (for example, DepthOfField or Bloom) then all post-processing is disabled, breaking the Oculus warp shader. For now, this fix is cool but we will need to find a better solution without having to edit ini files.

Thanks for posting this, though.

I recommend also going into UDKGame.ini to find DefaultPostProcessSettings and setting DOF_MaxFarBlurAmount=0.0

This will effectively remove the DOF effect without actually disabling it. Depth of field effects should be avoided for VR.

I only got my devkit today and was just testing some maps I built with UDK using the "Play on PC" function but the barrel distortion is really bad and those settings seem to have no effect?

Can you elaborate on what "really bad" means? Maybe take a screenshot and post it.

Also, have you tried the C++ or Unity demos? How do those look?

Turns out I'm retarded and UDK was running in 1280x720 XD
