Glow effect on hover

Greetings forum members,

I hope everyone is doing well. I’m currently working on implementing an illuminating effect on hover for an element, similar to the example shown in the attached image.

I’ve experimented with a selective bloom approach, but unfortunately, it seems to illuminate the entire object rather than achieving the desired effect. Any advice or suggestions on how to achieve this effect more effectively.

Any insights or tips would be greatly appreciated. Thank you in advance for your help!

See other recent threads on bloom, like Selective bloom not working - #8 by arjun_lokesh. We don’t recommend using selective bloom if you can avoid it. Instead set a bloom luminance threshold >> 1, and when hover is triggered on an object, increase its emissive value to something much greater than the threshold. For example you might set the luminance threshold to 2, and set the hovered object’s emissive intensity to 100.
