I'm using a sprite to have a muzzleflash appear when a gun is fired. This sprite also has a lightrange of 150, to make it that gunfire actually affects lighting around the area (to make it pretty, of course!). My problem is that the muzzleflash sprite is affected by light, no matter what I do. This results in the sprite being brighter if I'm moving forward, because of the lightrange. I tried using UNLIT but that didn't have very good results at all. What flag should I set, or what setting should I change to make the sprite fullbright?

Thank you!

BRIGHT flag?

It's still affected by it's own light, and by other light. :| The muzzleflash's other flags are PASSABLE, ZNEAR, TRANSLUCENT, and LIGHT. It also decreases in alpha somewhat slowly, rather than just disappearing in the next frame. These probably don't affect anything, but perhaps it's useful information.

you could give it's own material
Set it with full ambient, 0 diffuse and 0 specular.

Might mot be the best option, but you can tweak it to your own needs

Just set sprite's ambient to 100.

This worked nicely, as it's not affected by it's own light anymore, but it's still affected by the static shadows in the level, which is a bit odd for a muzzleflash. Is there a way to tell an entity to not get darker when it enters a shadow? If not, I'm happy with this result, so it's not too big of a deal.

Thank you!

I already told you, set ambient to 100!

I tried that, it's still affected by static shadows. D:

You could try changing its material to "mtl_flat".. it MAY help...

I havent tried, but I dont think thats helps 3run.
Ambient lighting will still get added to it I believe.

UNLIT is the way to go, I know you've tried it already, but it's the solution.

EDIT: UNLIT disables the PRV for the current entity. If you set this flag on entity creation, probably the material mat_unlit (or mtl_unlit, I don't remember) gets assigned. You don't want that, you want to keep mat_model/ mtl_model.
