Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

How to enable Motion Blur in VR mode?

Hi Guys,

I''m tring to make a VR Racing game. I want to add some nice motion blur effect when vehicle has achieved extremely high speed. Like what they did in Fast Neo Racing: alt text

The problem is I can't find a way to enable motion blur in VR mode. Play in viewport works fine but as soon as I switched to VR preview, there's no motion blur at all.

I have tried enable motion blur in project setting, camera, post effect volume and also modified DefaultScalability.ini to set r.MotionBlurQuality=1. Still no motion blur in VR mode.

I know motion blur was disabled in VR for the purpose of preventing motion sickness, but I really need the effect to exaggerate the burst of speed for only a short amount of time.

Does anyone have idea how to enable motion blur in VR? Any pointers that would assist in me troubleshooting this will be greatly appreciated.

Thanks.

Product Version: UE 4.14

I'm interested in this too. It seems motion blur is not yet supported in forward renderer either. Anyway to achieve a similar effect with cost would help a ton.

this could likely be replicated in a more friendly manner. if you enable blurring, itll blur EVERYTHING which means your character, and scenery etc. itd probably best to do the blur within the material of the object. i cant think of a perfect way off the top of my head but maybe something with world posiion offset+transparency and dithering.... or possibly even pixel depth offset? play around and see what works
