particles position and birth in XSI

#1

hey bros, i’m making the tutorial of creating a crater from andrew kramer but in XSI
i’m having the problem, the particles position in max, and the birth operator, are easy of use, but i dont know how to set in ice the particles so when the scene begin they didn’t birth, or emit, instead they stay in place from the begining, i know how to do it in other way, but i want to know how to do it in xsi, a lesson to learn for the future.

any explanation please, an thanks in advance

If I understand you correctly, you want the particles emitted, but not simulated: j
just delete the “Simulate Particle”-Node…
edit: and set the “Select Rate Type” in your “Emit…”-node to “Total Number of Particles”.

Yes, either disconnect the Simulate Particle node or set the speed=0 (I noticed he very quickly deleted the speed node when setting up the particle emitter in the turorial: http://www.videocopilot.net/tutorial/3d_crater_p2/ )

Either way should be fine.

For restricting the particles either use a piece of geometry (that you hide so only the particles show) or use a weight map in XSI, since there is a ready made “Filter by Weight Map” node in ICE.

To the shape node you may connect a Set Instance Geometry that references a group of one or more objects in XSI, to get the kind of debris you want on the street.

bad to say, but things are really complicated to do in XSI, very good program but lacks of certain areas where it’s suposed to be innovative, or at least replicate max, therefore the lack of information about the ice, im already paid for something that i didn’t know how to use,

too complicated for simple things, sad say

i’m a max user for some years and is not a good note for me ears, cant make a simple thing like this.

the shadow pass, the ambient oclussion pass, the material asignation, too complicated, but i’m sticking with it until i could do every thing,

thanks for the reply

Funny, those things are all very easy for me and I’m new too. Just keep at it man, you’ll get it.

It’s not complicated, in the particle emission node there are two options: “Number of Particles Per Second” and “Total Number of Particles”.
Just set to “Total Number…” and type there how many particles you want and that’s it.
If you want them to do not move after they are born, just set the speed to zero.

the shadow pass, the ambient oclussion pass, the material asignation, too complicated, but i’m sticking with it until i could do every thing,

Not at all, this is actually very easy to use. But as everything else in this world, you need to learn it.

good luck and keep asking and searching the forums.
