This seems like a basic question but i’ve been trying to create a red emissive material.

If i plug 1,0,0 to the emissive i get a red which is fine.

As i start to increase the value of the emissive the glow seems fine but the inside is more orange than red. How do i have the glow and that same red on the inside?

It took me a while to find info on this, so I’ll post it here for anyone experiencing the same issue. This appears to be functioning as intended due to the tonemapper changes in 4.15.
