Base Color is the color a surface gives you when you shine a light on it

So it wouldn't actually emit light by itself.

Emission is color that the surface inherently always produces

regardless of lighting

[soft ravine]

i think i don't really understand what emission color is

i thought it was something to use

for example

making a green object glow red

you set emission to red and main color to green and it glows red kind of thing

[calm maple]

suppose an object has a base color of red and an emission color of very faint green

[soft ravine]

is it related to light?

[calm maple]

In the dark, the object will be dark green

There is no light shining on it, so its base color doesn't matter

Its emission color is constant, so you see a little green

In dim white light, it'll be orange or yellow

you get some red from the base color, and you always have some green

In bright white light, it'll be red

with a tiny tinge of green, since that's still always present

[soft ravine]

oh

[calm maple]

Glow is not strictly caused by emission

[soft ravine]

so i can't have different colors for bloom in the first place

[calm maple]

Bloom simulates what happens when light "leaks" from extremely part brights of an image

behind the scenes, it's literally just a blurring of the original image that gets overlaid on top

(only keeping parts that are extremely bright)

I'm not sure how I would do a differently-colored glow around an object. I've certainly done outlines before.

I guess it'd be a similar concept, just with an outline that fades out instead of being solid

[soft ravine]

oh

than it seems like i need to make my own bloom to make that happen

when i set color to this

[calm maple]

can you show an example of what you want

[soft ravine]

it shows like 0.4, 1, 1 without bloom

and with bloom it glows too

[calm maple]

show your shader graph again?

[soft ravine]

but if i want to make it glow white

while being blue

i cant do that

[soft ravine]

oh those are 2 different shaders

my bad

[soft ravine]

(i tried adding emission by setting it to lit, adding value and switching to unlit but it didnt work)

i suppose there arent any builtin feature that lets me make objects glow without changing their base color

the main reason i need this is this ball under my character

if its rgb values are (0.4, 6, 6) it glows

it has a 1-fresnel effect

with gradient

to make it toony

its color gets multiplied each stage

so its first stage is (0.4, 6, 6) second stage is (.24, 3.6, 3.6)

the problem is only its glow is affected

by the g and b changes

while its r value decreases visibly

so at its first stage its visible color without bloom was (0.4, 1 , 1)

at its second stage its (.24, 1, 1)

only red changes

i can't make this glow because of that

its even more visible if its (6,6,6)

then its %100 white at every stage

main colors range should be 0-1 for this to work
