Re: rigid body simulation with more than one object type?

Hmm...

It seems to work, if the emitters are in the "per second"-mode, but if I switch to total number of particles, that emitter will not emit anything, unless its the first one in the order of execution. Any thoughts on this?

SOLVED: the seed needed to be different on each node.

Re: rigid body simulation with more than one object type?

Thanks for the reply,

I tried setting up 2 emit from null nodes, but only the first one gets executed. Is there something else I need to do, or is this something that doesn't work in XSI 7.01?

converting Max's A&D to mia_material?

Hi all, I was asking about this before, wondering why you can't transfer mental ray's materials from Max to XSI. Well, apparently there's no way to make it work directly via FBX or similar format as I was answered. Anyhow, I started thinking that it should be possible to export the settings for each...

Re: GI fills memory?

Thanks for the tip,

Must try that also. I actually changed to IRP in this particular (fire) project - it turned out to be much faster than with the photons and no memory problems either.

rigid body simulation with more than one object type?

Hello, How do you make a rigid body simulation involving more than one type of object? I was able to use "emit from null" to generate an object (or several of them) into a simulation, but what if I want several different objects? It seems that you cannot have more than one emit from null (...

Re: Setting photon color of instanced light?

Just another idea: Is there a way in the render tree to "pipe" color from another material?

This way I could get the color for the lights from a regular object, which in turn gets the color from the particles...

Re: Setting photon color of instanced light?

No matter,

I'm almost sure there would be a way to do this, if I weren't such a newbie with ICE :)

Re: Setting photon color of instanced light?

Good morning, Darn, if it's really missing from 7.01, then that settles it. I'm afraid the workaround wouldn't work in this project either. It is a fire simulation and I was hoping to control the light color by particle color, or in fact, the temperature of the light. I think I'm reverting back to p...

Re: Setting photon color of instanced light?

Right, the size is also above zero.

It also seems that the instance shape node is pretty picky too, those settings mentioned above are the only ones I have managed to use with lights. They render, but wont let me change the colors (with attribute_color).

Re: Setting photon color of instanced light?

Ok, I must be doing something wrong here. I made a very simple test scene, with just a cube and a point light and then a point cloud that looks like in the screenshot. The instance shape instances the point light (from the top level), hierarchy mode is at "object only", out-of-range is cla...

Re: Setting photon color of instanced light?

Amazing,

That's what I looked at too, as you posted the link the other time.

Somehow it just wont work with my tree (based on emFluid). I even tried taking it to another place, but no luck. I better try an empty tree next...

Re: Setting photon color of instanced light?

Very interesting!

I tried that before today (and just checked again), but I couldn't get anything out of the drop down (attribute color) other than "use default value". It doesn't seem to "see" the particles.

You must have instanced the light differently - how did you do that?

Re: Setting photon color of instanced light?

Hmm, I think I get it now, there's no way to make this work, because each particle would have a different color in each frame and there's only one light, which is been instanced. Is there a way of casting the particle shape? Like "get particle shape" and then convert that to whatever object?

Re: Setting photon color of instanced light?

Hello again, Slight progress, but then another dead end. I managed to set photon color from my point cloud, but only if I set a constant value for it (set data). The good news is that it actually changes the color of the photons accordingly, even though I the light has been instanced before changing...

Re: GI fills memory?

Well, it just freezes and gives me the hourglass (or the weird torus thing Windows uses now). After a while Windows wants to kill it, because XSI process is using something like 99% of memory. I haven't tested rendering actual passes today, only regions, I will see if I get the same behavior later t...

Re: GI fills memory?

Thanks, I will also post here, if I figure it out on my own. I'm pretty sure it's related to GI, I'm working with the "fire project" and there's quite a lot of photons involved. Few frames come out ok, but the photon maps accumulate in memory and after a while it crashes. I am not sure, ho...
