There are a lot of oddities to configuration that needed adjusted. My
hope is that this helps others starting to use UE4 for Oculus Rift
development:
DOOR PROP SCALE
The scale of default door and frame are wrong.
The door is 200cm tall. That is 6.56 feet. Doors in my house are 6.8
feet. This means you need it to be 208cm. That is a scaling factor of
1.04. That doesn't mean I'm going to use their door frame but if you are
using that to gauge if scale is correct in the game, 3 inches is a big
deal. I felt like my head was scraping the top of the door.
PLAYER HEIGHT
I'm 5 foot 8. The default height for a player is much taller. To adjust
this go to the MyCharacter blueprint, click default and search for
height. you want to set "capsule half height" to 1/2 your height in
centimeters. My height is 172cm/2 = 86.
POST PROCESSING VOLUME
The next set of
adjustments require a post processing volume. You can find it in "All
Classes" if you don't have one. Drag it into your scene. search for
unbound detail and check that so it applies to everything.
MOTION BLUR
There is a blur as you approach objects. This is an anti-alias method of
temporal and it is super annoying. search the post processing volume
for AA Method. Set that to none.
LENS FLARE
Lens flare has to go. Search for Lens and set the Intensity and BokehSize to 0.
AUTO BRIGHTNESS
Scenes in the rift get unusually bright. That is auto exposure. Search
for exp. I don't know exactly the best settings but I am using min
brightness = .5, max brightness = 1, auto exposure = 0.
IPD
The other
thing that bothered me was the IPD feels different. Up to now I hadn't
adjusted it on the DK1. UDK3 felt perfect. I had to adjust it for UE4 to
make it not give me a headache.
INITIAL IMPRESSIONS
My
initial impression with UE4 versus UDK3 is that it doesn't feel as nice
in the Rift. UDK3 felt like Half Life 2 which was very 'crisp'. UE4
feels more 'fuzzy' like Unity. UE4 certainly comes packed with more
flexibility but it feels like a step back for Rift support.
That is a start I will update this blog entry as I discover other things to make UE4 development easier for the Oculus Rift.
