8000 Deviation Comments / Volumetric Smoke

Fri Oct 20, 2006, 1:26 AM

Yay me!
Those are the number of comments i have made on other peoples deviations right?

Extrude normal is way better than extrude by individual polygon in the previous version!

hmm.. so has anyone ever tried doing a smoketrail effect before? i was wondering what would be a good way of doing this. I want to be able to define a smoke trail path using splines like i do with my pipes and have multiple rockets being launched out from my bays.. but ive never done that before any ideas?

Could you not give a particle emitter a spline to animate along like you could animate anything along a spline? I can't remember how you animate something along a spline, but i remember doing it in the past, i'll go have a look, i was thinking about this sort of effect just today lol

Congrats on the 8K also

The way i did it before only works for meshes, but I found the 'proper' way of doing it now anyway:

>Make an emitter
>Make the spline-path
>Select the emitter and go to Animation>Constraints>

ath constraint and then select the spline with the cursor that comes up

now if you hit play it will follow along the spline, if you want to change the settings go to the motion panel with the emitter selected and you can change the settings in there..

hope I've helped in some way

Particle Emitter ftw.
I know theres a tutorial in Max that does the same thing, though it uses the emitter and some grav space-warps.

hm, thanks for that, i just need to figure out how to get smoke onto the particles now. I have tried a glow on GBuffer ID but that seems to only do bright colours and it doesnt generate dark ones like grey. Maybe i have to use meta blobs or something and then use material properties

hm . . I whould trie it with particleFlow
first I whould animate some help-object anlong the spline and use "Position Object" in particleFlow, dont know if it works, didn't trie it, but why don't you use the "Find Target" ?
