You can add uniform RGB values to entire models with ModelComponent:setEmissiveColor() or the emissiveColor field in the component definition, but this is additive rather than multiplicative so it is nothing like changing the "opacity" of the emissive map.
But you
can add negative emission color; and this can be animated via scripting.
Example:
Code: Select all
forest_oak_cluster_1.model:setEmissiveColor(vec(-.025))
forest_oak_cluster_2.model:setEmissiveColor(vec(-.01,-.005,-.05))
forest_oak_cluster_3.model:setEmissiveColor(vec(0,0,-.01))
forest_oak_cluster_4.model:setEmissiveColor(vec(-.025,-.01))
forest_oak_cluster_5.model:setEmissiveColor(vec(-.01,-.025,-.06))

thanks minmay, I hate to ask this stupid question but how do you destroy it at the end again. I use to kind of know this but.. well its gone lol.

Thanks Isaac for your input on that, I might use that idea but I was hoping for more of just a noise on the emissive map. But since I can't do that, I'm not going to mess with the fluctuation idea
The mushrooms I created still look good as they are

Materials do have an onUpdate hook that allows realtime adjustments to [some of] the various internal settings.

Here is a more clear shot. I don't know, do you guys think these might look cooler with a fluctuating emissive?

They look nice.
They could look great with pulsating luminescence.
They could be breakable, and could be food—or poisonous.
IIRC, in the ORRR2 mod, Xanathar put in psychedelic mushrooms that sent dancing chorus girls across the screen, with a moiré pattern background.

You know I wonder if I could have a rotating overlay on/over the emissive. using an alpha channel maybe?

Alpha channel is either on or off, I think; no middle degree of transparency.
Translucent blending mode can —sort of— come close to a similar effect, but not really.
*Edit: removed text about alpha values.... AFAIK they are single bit—or are treated that way. I don't recall ever having success with a partially transparent material where the alpha areas were not completely on, or completely off.

So if I were to use the first idea you had, how would I go about it (I'm still very much a scripting newb lol). would it be in the defineObject?

You can start with this:
viewtopic.php?f=22&t=7951&start=2770#p119082
For the mushroom effect, I am not sure that it can be straightforwardly done, but there might be some way to come close to it.
It might be possible to bake part of the effect into an animated material, and include a fluctuating light component.
I have not tried anything like that —yet.
