Hello, I just followed a very simple tutorial [https://www.youtube.com/watch?v=Q4MW3T4VpxM] and I don't seem to be getting any glow (emission) effect. I will specific provide information below.

First, here is the glow effect I was hoping for (from the video):

#

Here is what mine looks like (top left cube has material + shader applied) and also shows the shader settings :

#

here is the shader :

#

Here is the material :

#

Last thing I can think to provide is the camera :

#

Any ideas...it all seemed very simple

Bloom must be enabled in your post processing volume

#

And either bloom threshold must be decreased or HDR rendering must be enabled so high color intensities aren't capped in brightness

Ok, just enabled and set the intensity and it worked great.

#

So...I haven't done much with volume manipulation. Everything I'm doing is via code...is it normal/ok to enable/disable bloom dynamically?

#

Or is better to swap precreated volumes? Or just leave bloom enabled all the time?

#

Should be fine to modify them from code, as long as you keep track of what data you're modifying

#

Because they exist as assets, modifying one typically either creates a temporary instance, or modifies the asset itself until the game is reset
I don't remember how it worked with volume profiles specifically

Ok. Thanks so much. There is so much to know! It really helps to have someone to ask for these things...saves me tons of times. I really appreciate it!

I'm not sure what you mean by "they're". I have a GlobalVolume that is part of my Bootstrap scene which is attached to my main camera.

#

I was planning on just programmically enabling bloom temporarily on that.

#

I'm not 100% sure how much performance this stuff matters...like I have this glitch effect that jumped through hoops having it attached to a different camera/volume which I bring in via a scene and enable/disable. I don't know if I actually just made performance worse but I only use it every now and then so I figured it was better not to have it around when I didn't need it.

Ok..that makes sense

twin lintel
#

But I'm not 100% sure when and which features are affected by shader stripping so best look into that

brave zodiac
#

So maybe create a volume that uses bloom, or just enable it for everything and adjust the intensity

#

Any suggestions on how to learn about that stuff?

#

Happy to read etc...just not sure the best spot.
