Lighting is too glowy and over-bright

[marscaleb]

I've created some grass using mostly a solid color. (I'm trying to match a desired artistic style.) But once all the lighting has been built, the grass is super-bright; brighter than the original texture. Way brighter.



I've filled in the corner with the original color, which is what I want the hills to look like, maybe a little brighter in the direct light, and shadowed on the shady side.
I also tried creating a texture to cover the hills with when they are distanced from the camera, so it still looks like grass. I started off using a solid color, the same color in the corner, but this also turned into this super-bright off-white that glows.

This was built starting with the default mid-day lighting map. I'm really not accustomed to working with lightmass and so I don't know how to tweak this.

Looking at it, both the texture and lighting are quite bright; if your directional light is pure white with a brightness of 5 and your texture is something like a flat 200,220,150, then the output could conceivably be 1000,1100,750 - which is likely going to look very bright and glowing

I usually try to avoid directional lights with brightnesses greater than around 1; the default UDK maps do use some strangely bright lights.

Strange. I remembered using lots of grass in UDK asset with Midday template. But they look all green and all. Any chance you tweaked on the light or the WorldInfo?

It is possible that lightmass is grossly over-exaggerating the problem too. Might be worth checking the diffuse bounce in both lightmass and the material settings. I would turn it down pretty low in the material.

Do the assets have lightmaps?

The grass shown here is nothing but the grass that came with the foliage demo, but with the diffuse channel changed.
