how to use staticmesh as a light source to light the scene?

Hi,

I know UDK has a option “use emissive for static light” to light the scene, but where can I find it in UE4 or is there a another way to do this?

Thanks!

Hi,

This feature has unfortunately not been implemented in UE4.
The reason is appearently some issues with integrating it into the static lighting building process…

Its a bit explained in detail here:

PS: HoHoHo :slight_smile:
It seems it has recently been integrated afterall :smiley:
Check your material option for “Emissive Dynamic Area Light”

“Emissive Dynamic Area Light” needs LPV to be turned on. I think he asked for a Solution to bake Emissive Light via Lightmass. This feature sadly doesnt exist anymore.

Thank you!

It’s too bad,…But, it’s a very useful feature.

Yes, it is.

The UDK method was actually pretty crappy, so I’m not missing it much. Hopefully we’ll get real emissive lighting along with area lights at some point.

According to the LPV update from LionsHead this should be making it’s way back into the engine soon, possibly in 4.5.

In this case, Alexanders post, intended to clear up some confusion, actually creates it :rolleyes:
My initial joy was fueled by his statement which conveys the idea that the Emissive Dynamic Area Light, in conjunction with LPVs, is equivalent to the emissive lighting feature:

In the context it appears as if “this feature” refers to the emissive lighting as we know it from UDK.

Cheers,

The quality result of using Emissive lighting with LPV is very poor, so I wouldn’t get too excited.
