Pyrocluster, shadows and tS7.51 // Archive: Tech Forum

I am having trouble at trying to make a Pyrocluster steam spray to cast shadow.
Turning the Cast Shadow button on, in the Shadows tab/panel does nothing.
I have an infinite light casting shadows in the scene, ray trace is on, every thing should be okay... but there is still no shadows.
Is it a bug that comes with tS7.51 ? (I haven't tried to load my scene in tS4.3)
Any idea on what is going wrong ?
I don't use Pyrocluster so maybe I forgot a key setting...:o
Oh, BTW, I tried to render the scene with Dribble : Dribble does not render Pyrocluster :( |

I suppose it depends on how you made the cluster.
If it's like Dele's here:
http://forums1.caligari.com/truespace/showthread.php?t=3804&highlight=particles
Then I don't see why not as the objects are primitives.
If it is an image or a shader assigned to face, point or edge, then it probably won't cast shadows.
Did you make it yourself?
Or is it from trueparticles in the modeler side? |

If I remember correctly 'raycast' needs to be selected as well. It's been a while since I've used Pyrocluster tho, so that may not be of any help. :) |

I have tried raycast and scanline. Same issue :(
@ Jamesmc : Pyrocluster is a professional plugin for Modeler. See below : |

i gave this ago last night and pyrocluster doesn't seem to like infinate lights. try a spot light with a shadowmap. i'll try and post an image in a min |

ok heres a screen shot of what i got working:

is that the kind of effect you were after? |

just noticed too you have to alter the 'transparancy' setting under the shadow tab in pyrocluster to get them to cast shadows if you're using raytraced shadows |

Anyone tried these in with VRay or Dribble? :) |

I think Emmanuel said it doesn't render in dribble,which is disapointing. I've not tried it with vray though.
Edit: Doesn't render in vray :( |

Bummer. Shame there isn't a way to turn it into geometry. |

you don't fancy rewriting pyrocluster so it works on the workspace then jack?;) |

LOL, think that one's a bit out of my league. ;)
And besides I'm supposed to be working on the Kerkythea export. :p
I suppose I could probably come up with a simple particle generator if I had some free time. The problem is that their are limitations with the current encapsulation system, so until those are addressed it might be more difficult than it needs to be. That was similar to the limitation I ran into back when I tried to write ArrayIt! for TS 3.1. Eventually I gave up on the project because it proved to be non-feasible.
Hmm.... now you got me thinking about it. LOL I might just have to do it... if someone could write a nice billboarding object that would help a lot... |

What I'm going do with the particle fire and smoke I'm making in another program is put the file to transparent png files.
Then I'll convert the particle animation to png, compile again to video and import on a plane as a transparent texture.
Hopefully the fire and smoke alone will show up alone and I can position it where I want.
Haven't tried it yet, but it might work as transparent planes of images work.
That way , I can use the native renderer in tS. |

Yes, that works ! Thank you Jayr.
I could get my shadows to work with infinite light after many try/error also but the result is not as good as using the spot.
Problem with Pyrocluster is that it has so many parameters that influence each other, you never know what is going wrong :D
I purchased Pyrocluster in tS4.3 days and I realize that today's hardware allows me to create the effects I always dreamed of :) |

I know, i did the same thing. I created an explosion that would have took 2 days of solid rendering t get it a 640x480 when i got it in 2000!
The transparency thing makes some odd shadows when you useraytraced shadows, probably useful more for fire than thick smoke though |

Some nice effects there. Is pyrocluster still available and is it problematic with tS7 like clothmotion?
Also, can the built in truparticles do such good fire and smoke as Jayr's example? |

i don't know if it's still available, maybe as one of caligari's paks but cebas doesn't list it for truespace on their site.
as for it's stablity, i don't think i've ever really pushed it to breaking point, it's such a complex plug-in i feel like i've never make best use of it.
i've not messed around much with trueparticles, i'm in an experimenting mood though.... |

a VERY quick test, but a good start i think. This is trueparticles with the x-ray shader from simbiont tweeked and applied:

Not there, but like i said it's a start |

For stills, you could get faster results with trueParticles and good materials, but in animation, Pyrocluster is the best, as it is a true volumetric tool.
Its effects are oustanding.
I am currently doing a serie of animations for factories plants and I am re-learning its subtitlies with lots of fun.
So sorry I can't show it here, because of top secret agreement :(
Note that Cebas is still alive and fast at registration. I had to re-register Pyrocluster as I re-installed it and they returned the email with ID key in one day.
BTW, perhaps, we should backup Terry Halladay's long tutorial (http://www.tsdepot.co.uk/tutorials/advanced/pages/pyrocluster/index.php) before tSdepot website get closed. |

Thanks for that Emmanuel, i had that tutorial once, printed out, but lost it. |
