4.4 emissive light error

I created a new map with 4.4 and if I make any of my materials emissive and turn the light up decently around it starts flashing randomly and the material looks like static and glitchy…

Does anyone know what’s happening?

Hey AttemptD -

Are you using the Emissive Checkbox setting so the material is injected into the Light Propogation Volume and if so have you turned that volume on? Of the materials that are experiencing this issue, what if anything is plugged into Emissive Color?

Let me know and Thank You -

I’m not sure what that means. I have a color plugged into the emissive of the material node in the material editor as always…It’s just very flashy bright and static like?? Apparently one of the occlusion volumes cause problems with particles that were emissive in 4.3…I’m very confused.

Hey AttemptD -

Sorry for the confusion, the LPV is still in the experimental phase and I wanted to make sure we were not dealing with that in particular.

Now that that has been cleared up, can you describe what you mean by “turn the light up” Are we talking Movable, stationary, spotlights or point lights or are we talking a directional light? You mention a particle is that what the material is getting applied to?

Let me know so I can track this down for you.

Thank You and again sorry for the initial confusion

These are all questions I should answer myself. I’ll get back to you soon with further details. And not a problem at all. I appreciate the help.

After playing with it some more if I send a number in the negatives via scalar or vector in the material editor I get some nasty gleaming lights emitting and some static stuff…wasn’t there a bug with ambient occlusion or something?? How could I fix this without taking detail away from my game?

Hey AttemptD -

I am not having much luck getting the effect you are experiencing. Can you post a screenshot of your material setup?

Thank You

The negative problems were definitely still a bug. We were told a while back to disable a certain type of ambient occlusion via post process to get rid of the problem and it worked.

Just letting you all know there’s something wrong there. It’s work around for now and I don’tr think it hurts my quality…\but neither way it’s a fix temporarily.

thank you
