| Post subject: | Additive alpha models |
So I'm adding tracers to my game http://www.youtube.com/watch?v=pJuwFMEWO3M and I figure I should look at the issue of alpha blending the tracer mesh. But before I dive into it, I wondered if there is already something in there I'm missing? Do any of the existing shaders support alpha? I added alpha testing to my own shaders, but wonder if additive is a different beast (aside from the sorting issues of course). I'm trying to not get bogged down in too many details (like the particles really not working too well for instance). On to more city generation tommorrow. |

What you could do is adding a new context to the model shader which sets the blend mode to additive. This context can be referenced in the pipeline, similar as is already done for particles. |

Weirdly enough, I'd already done that, just forgot I'd done it. Fixed now. |
