Emissive + Translucency

Hey guys. Long story short I’m attempting to make a holographic HUD and am looking to create a translucent material that is emissive. decals will not work as the HUD is made from mesh and needs to float in mid air.

thanks.

What have you achieved so far and what are you having trouble with?

opacity and emissive work in opposite to one another. as opacity drops bloom is destroyed. compensating by increasing emissive only counters opacity.

Hi GBrodeur -

Instead of Translucent Materials, try using Additive Materials. This should allow you to get the Translucency you want and still activate the bloom.

I have attached a sample Project for you to test.

Almost. I think to better explain, I’m trying to achieve an edge bloom while still maintaining a high level of transparency.

transparency seems to be hard to maintain especially with desaturated colors.

Hi -

One possibility to achieve the emissive you want but also give the Translucent effect close up would be to use a Near Camera Fade to control a LERP between the two emissive and opacity states of the plane.

I updated the project here for you to take a look at:
