Imagine a semi-transparent cube.
A light inside which would flash.
I’d like to see the result of those flashes on the cube faces…. from the outside of the cube.

If anyone knows how to approach this, I’d be happy :)

best,

post a patch!

I did that.
Thanks for your tips (I did that too testing movement around an object:

Now, I'd love to have some atmospheric effect.
not only a fog, but like halos & things like that … another huge step for me :)

that’s what you should be using to get a glow/halo effect.
it has to be produced on the texture in screen-space.

texture in screen-space is a concept I didn’t totally get, which means I’ll study it in the next hours.
