Material Emission Total White Issue

I have this Soda Machine that is supposed to emit light in a totally dark scene. There is some plastic where the logo is. That’s the part of the Soda Machine that is supposed to emit light. I have a emission map to tell the material where to emit light.
The issue is that when i crank up the emission, rather than showing the texture, it’s just showing a color. If i wan’t to see the effect of the emission, i’ll have to crank it up so high that the texture becomes completely white. I wan’t it to be like unlit where you can actually see the texture.
I have come up with some ideas for a solution.
* Find a way to make the texture not turn completely white when turning up the emission and just make it shine in the dark.
* Blend shaders: I don’t know if this is possible, but if there were a way to blend the standard shader with a unlit shader based a black and white image.
* Remodel and seperate the emission part from the rest of the model and have two shaders. This is not something I wan’t to do, but if there’s no other way…
I don’t know.

Hey there!
So yeah, when an emission get too bright it goes white.
What you might want to do is to enable HDR on your camera. This might help a bit.
 
Creating your own shader won’t help much because emission still remains emission…
 
I think you want to look into bloom. This is an image effect that make bright things bleed a bit of light.

Unity has it in it’s effects package on the asset store.

Sorry, but this is not the issue. The issue is that when i crank up the emission, I can’t see the texture. I wan’t to still be able to see the texture when I make it brighter. I don’t know if this is even possible though. -_-

Well that’s the problem. You can’t make it be brighter without it going white. But with bloom you can make it appear brighter.
