increasing emissive intensity turns to white color. Only for higher values of emissive but in orde to get the glow, it must be turned a bit high. Problem is when increasing intensity everything starts to turn white.
Is this a bug or any way to solve this?
I have always solved that problem like this:
Enter a value 100 or higher and your material will start to turn more white
That’s what happens when you turn up the intensity high enough
to explain it a bit better:
found this image somewhere, but it does not really work.
On the left is what I get.
On the right is what I want.
Intensities are the same but the right picture shows emissive that stays red and glows red.
How do I get that effect?
You would have to change the bloom effect
This thread has a lot of information on the issue you’re facing:
Thank you.
That thread was very useful
Can you tell us how to do that, please?
In the editor hit ~ to open the console and type in

This will keep glows the color they should be.
You’ll need to do it everytime you restart unreal, but there’s a way to set it in the .ini files, I just can’t remember how.
