Rain And Night (Emissive problem)

Development Rendering
1

Hey all,
So I’m using rain from example content and everything was fine while there was sun shining… Now when I turned my scene into night, the rain looked rather white, as you can see here:

Then I thought to myself, well I should unhook emissive color to the rain material (M_rain) and I did.

The white has gone away but I can barely see the rain any more, and before doing this the rain was quite pouring to say the least…

Is there a healthy balance to no emissive color and full emissive color to the rain material? :frowning:

Thanks!

Hello,
I move your thread to rendering section.

The emissive is what makes you be able to see the rain clearly. Maybe you should plug it back in and just lower the emissive value a bit.

I’m guessing the material is unlit/translucent ? You could try switching the blend mode to modulate.

You can always use this type of setup and a scalar value with a multiply to control the intensity of your emissive channel.

That solved it Tim/Firezown! Thanks for help!
Tim, I’m also using your night vision, pretty stuff! :slight_smile:

pylb, thanks for suggestion, but once I tried tweaking emission with a value, it worked so well that I didn’t need to make any further modifications :slight_smile:

I can’t take credit for the Night Vision stuff. I used the material setup someone had made in UDK and implemented it the best I could for simple use. :slight_smile:

I’m not a material wizard like some of the other awesome devs out there but I’ll tell you that I use multiply’s, scalar parameters, and material instances a lot so I can adjust things on the fly. It’s up there as one of my favorite things with the engine. There are some awesome big features in the engine, but sometimes it’s just the little things like that make it so much easier and fun!
