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:

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.

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

Execture console command vr.AllowMotionBlurInVR 1 (1 = true, 0 = false). This command will allow motion blur to be enabled even in VR.
