Can I achieve the convolution bloom effect for a light source without the convolution bloom?

[Robert35025]

I need that effect for my flashlight to make it look more aesthetic and realistic but i can’t seem to find anything about it other than niagara. However the problem with niagara is that it’s too flat. The convolution effect looks 3D and real but the niagara that tries to act as the glare just looks like a 2D plane and fake, which is not ideal when another player walks by and looks around and it all looks weird.

Is there any solution? Any way to do it?

You’re going to have to do more than just a billboard with the shader.

There’s tricks like this

Any idea on how to recreate dooms volumetric glow with vertex shader?

Hi there, because there is no (cheap) bloom for mobile without mobileHDR I am searching for a low performance alternative. Some years ago I stumbled upon Simons Blog and his analysis of Dooms volumetric glow: Doom 3 – Volumetric Glow | Simon schreibt. And someone implemented it with a breakdown in his game: Yzer development picture dump (yzergame.com) [wireframe] But my goal is to not rely on game code to update the vertices, but instead have the vertex shader push around the vertices. Maybe…
