Line Particles Rendering

veirdo · 2014 Feb 24

I don't know is it a feature, but looks like a bug. The line type particles with additive blending option have a strange behavior. They're rendering additive against world and themselves, but not against other particles.
That rendering issue is dday version and video card independent.

Kind of related (i.e it's particle rendering), but not at the same time.

Particles aren't rendered at all behind wall textures that have translucency ; they have never been as far as I am aware. Dynamic lights and halo's appear to be.

The only way to currently have a wall texture with translucency, is an external graphic replacement; a png or similar in the textures folder, which is relatively obscure.

But Boom has a translucency linetype, which will make this oversight more apparent in future; a mapper can choose to make any wall on their map translucent.

but the pt_line particles are not blending with other particles except there self and the world witch is quite strange.

Vermil · 2014 Feb 28

I've asked Deng Team about the additive blending issue and long story short (I figure it's best I don't try to reword the technical part), it's basically a limitation of the particle system and renderer.

Deng Team will be considering whether there is an efficient enough method available these days, to use in the new renderer and associated new particle system, that doesn't have this limitation.
