Dynamic Lighting only working in left eye

I followed this tutorial and got dynamic lighting working with my level:
http://allarsblog.com/blog/2010/09/12/day-and-night-cycle-tutorial/

Everything looked fine until I put the rift on. As the directional light is rotated via kismet, none of the lighting changes are reflected in the right eye. ie: mesh lighting is not adjusted and shadows are not moving. But in the left eye everything is fine.

Am I missing a setting?

If I find an answer I will post it here.

Should have done more digging on the forum. I see this is a Unreal engine bug:

Well... that kinda sucks. I hope it gets fixed eventually.

I installed the latest Rift UDK (2013-09). It didn't fix anything:

A couple of things I figured out:
1. DirectX11 mesh lighting for a moving directional light is bad in the right eye. If you intend on moving the directional light (ex: 24 hour light) you will need to use DirectX9.
2. Dynamic shadows from a moving directional light are a problem in the right eye regardless of DirectX version. You will need to turn that off (as stated previously)

I ran into a few gotchas while implementing it that you may be interested in:

Yeah, I think this has been broken for a while. I thought it was fixed recently, but maybe not.

Dynamic shadows issue is definitely fixed, just not published yet.
You can download a preliminary fix from here:
32-bit UDK.exe: https://static.oculus.com/sdk-downloads/udk_32bit_fix_no_simplygon.zip
64-bit UDK.exe: https://static.oculus.com/sdk-downloads/udk_64bit_fix_no_simplygon.zip

Note, these files are compiled without Simplygon, and they are not digitally signed (therefore, will not be included into installation package by UnSetup.exe). But could be good enough to try.

As to the first issue.... Can you make a simple map as an example of the issue and send it to support@oculus.com (in subj specify 'for artyom17'), and I will verify if the issue is already fixed or not, and if not I'll work on it?

Just tested the 32-bit version of this fix to see if dynamic shadows would work and while I can confirm shadows now appear in both eyes correctly (e.g. foliage demo), head tracking has stopped working. Are there settings to change or is the executable not working properly?

I believe it is fixed now! I don't really know for sure if it is though because I primarily use a custom engine to make my games for the oculus.
