Re: Can I get a little help understanding ICE states?

Thanks, you're right that was it. So what's the difference between particle size and particle scale?

I'm going to leave the compound here in case anyone wants it.

Re: Can I get a little help understanding ICE states?

Well if you trigger test for velocity just after curl noise, curl noise won't happen since you move to another state just after particle starts to move. Ok, but this doesn't work either, because the null just makes a hole in the particle field. I can make the curlnoise work if there's no attempt at...

Re: Can I get a little help understanding ICE states?

I can definitely make it work if the null starts inside the particle grid, but not if I move it into the grid.

Re: Can I get a little help understanding ICE states?

Thanks for all the help Steve. I don't want to lead you down a black hole, but can you help me understand the next step? I want to scale the particles down to 0 from their "launch" time after the curlnoise state takes effect -- not from their birth. The problem is knowing which trigger to use. This ...

Re: Can I get a little help understanding ICE states?

Got it finally. I wasn't setting the state ID's properly, now I'm understanding how this thing works. It takes me a little longer than most people, but eventually I'll figure it out.

Re: Can I get a little help understanding ICE states?

Thanks...I got the particles under the null to change color, but I still can't get the curlnoise to activate. Would that get plugged into a port on the State node, or in the Simulaiton Root node---and which port would it be? Execute on trigger?

Can I get a little help understanding ICE states?

I've been trying to set up an effect, but without the result I'm looking for. I have an object that's covered with particles. I want to use a null to move the particles off the object using the curlnoise framework node. I can do that by using modulate by null, but the problem is that any particles t...

Re: Turbulize particle velocity -- some particles get stuck

yes its a known problem with strong turbulance that particles get stuck in 'valleys' (not just in XSI :D ) try curl noise instead, whilst a bit more setup I do believe that is what it was designed for and you will not get particles 'stuck' unless there is some other logic in your tree making them '...

Turbulize particle velocity -- some particles get stuck

I've noticed that every time I use that node, there's always groups of particles that hang in the air, while other do their thing and move around correctly. Does anyone know why this happens?

Re: Cached particle sims won't read properly

I was using cache on file node to write and then read. And it has worked for me many times. But now it works when it wants to. I've also tried using the cache manager and mixer, and everything seems ok until I open the scene again. Then there's nothing there when the sim plays. I've had this issue i...

Re: Cached particle sims won't read properly

If this helps any for a diagnosis, sometimes I get the red error message at the bottom that says x cache file could not be found. But it exists and is in the right place.

Cached particle sims won't read properly

I was trying to render a scene with a color pass and Ao pass. Once the color pass is done, and it switched to the Ao pass, the particles stopped reading. Then they stopped reading on the other pass too. Is there any special trick that'll make the cache on file node work properly?

Re: Memory leak when working in a certain scene.

I had noticed that the RAM was running out when making a Capture preview (3600 frames). Actually, when letting the animation play in the timbar, I noticed that my ram usage increases with each tick of a frame. Does that specify anything?

Memory leak when working in a certain scene.

I'm finding that if I work in this scene, my 32GB of ram is eaten up and my computer slows to a crawl until I kill XSi in the task manager. Is there any kind of troubleshooting i can do to see what is causing this issue?

Re: Scene hangs on open because of "resimulating time samples".

Thanks I'll remember that trick next time. In this case, I just merged the scene into a new one.

the odd thing about that re-simulation that always happens is that all sims are cached, so I'm wondering what Softimage is doing if its not just reading the cache files.
