How can I achieve selective glow with custom model?

[EvgeniiFilippov]

Hello guys, I am new to three js and I am trying to recreate the bloom effect for the bowtie model
I want to achive this type of edge glow while keep other objects on the scene without glow effect

I have this model

And I have created a separated edge object that I think can be converted to the bloom object

I have tried the selecteive bloom example, but this is overcomplicated for beginner. Could you please provide some really simple example let’s say with two objects, one with glow and one without?
I also thinking maybe it is easier to achive with shaders?

thank you in advance

don’t worry about the official example.

EffectComposer UnrealBloomPass is ruining my whole render thing

that’s usually when near/far is too wide. either try to set them more narrow, or try logarithmicDepthBuffer. also the final pass, you don’t need that. bloom is selective out of the box, people just use it wrong. the official bloom demo is making something that is so easy seem overly complex. all you need is unrealbloompass with threshold 1, and now you can select on the materials (emissiveIntensity). see: Selective Bloom not working in react function with vanilla js wrapped in useeffect - #2 …

Thank you, I was able to achieve this effects with pushing colors beyond 1, but is it possible to make the edges more smooth and make the pixels on the edge have less opacity than closer to the center of the curve?

you probably forgot target.samples = 8
