That would be so awesome, if somehow we assign the glow shader to an object and see it glowing by itself.
Any entry points?
…
The glow shader is a postprocess shader, and so cannot be assigned to individual renderers. However, it supports selective glowing via the alpha channel of the frame buffer. Read the Details section on the Glow page in the manual.
Flashbang’s technical blog had a nice piece on how they achieve per-object glow using render textures and a replacement shader which doesn’t rely on the object or scene alpha.
Too bad, cuz you see, I was intending that the glowing object is moving so, assigning a seccessive frames of alpha channel is no way even if the movement is expected studied.
BUT i managed to apply the Noise effect to one singular object using Render Texture, it was good, sadly the glow and other effects are not remarked using this technique.
to the wish list then… 
Since 2.6 or 3.0 (unsure which one), there is a selective glow replacement shader on the replacement shader page. did you give that a go?
Can you clarify your problem? What have you tried, and in what way is it not working? Have you read the manual page explaining how to control the glow effect using alpha?
I’ve found a video that references that exact glow issue.
Glowing on certain objects right? It can be done using URP & Post Processing.
