The object runs through a partical system. The particles are randomly mapped through sub object materials. As they go through the collision event I want one of those sub object materials to switch. I am challenged by the randomizing of the materials on the particles through sub object as it loses the sub object ID's that are sub to the randomizing. Any ways around this or different ways to approach? Basically I have a "transaction object" that is multi-sub object (4 materials) that needs a decal to switch to a different decal. 2012-05-24T20:45:14+02:00 http://area.autodesk.com/forum/autodesk-3ds-max/particles---dynamics/massfx-question/page-last/ http://area.autodesk.com/forum/autodesk-3ds-max/particles---dynamics/massfx-question/page-last/#When:04:40:34Z Good Morning. I am having a bit of trouble utilizing Massfx in my current workflow. I have an excavator that is digging a shallow trench in the ground. I have rigged up a whole mess of dirt fragments to be dynamic objects starting in sleep mode, and the bucket to be a kinematic object meant to dig them up. However, as illustrated in the attached images, when the bucket touches the first object, the entire trench explodes. I've monkeyed with their bounding boxes, density, initial speed, bounciness, everything I can think of. Anybody have any ideas on how to fix this? 2012-05-24T04:40:34+02:00 http://area.autodesk.com/forum/autodesk-3ds-max/particles---dynamics/particles-not-rendering-at-all/page-last/ http://area.autodesk.com/forum/autodesk-3ds-max/particles---dynamics/particles-not-rendering-at-all/page-last/#When:07:09:54Z Hey everyone, I'm just throwing out there that I'm very much a novice at 3ds Max (Going through my first formal course this semester) but I'm having a problem with ALL of my particle systems not rendering. I've started by making a PF Source from the back of one of the spaceships, and while the actual particle system shows in the viewport, whenever I render the scene it doesn't show anything. I'm sure I'm missing something minor but for whatever reason it escapes me. I've attached some screenshots so you can see what I mean: Viewport- http://i41.photobucket.com/albums/e253/Thalkwondo/2012-05-21211401.jpg Render- http://i41.photobucket.com/albums/e253/Thalkwondo/2012-05-21211408.jpg I've even created a new scene and tried that again, wondering if there was some form of corruption in my original scene and still the problem persists. The scene from the screenshots is set to scale at about 4 miles by 4 miles. I've tried using both the Afterburn particle parameters and the basic parameters and nothing helps. I've tried increasing the size of the particles, the shape, adding materials, scaling the object to be larger and still nothing. Here's what I'm running: 3ds Max 2011 Student Edition Afterburn 4.0b Vray2 I'm sure there will be followup questions, so please feel free to ask. Thanks in advance for any insight 2012-05-22T07:09:54+02:00 http://area.autodesk.com/forum/autodesk-3ds-max/particles---dynamics/realistic-sand-animation/page-last/ http://area.autodesk.com/forum/autodesk-3ds-max/particles---dynamics/realistic-sand-animation/page-last/#When:05:43:15Z Hi all, I need to create a shot like the 'sandman' formation in spiderman 2. It would be around 20-30 sec. I would like to know the efficient way of doing it. reference : [url=http://www.youtube.com/watch?v=Txnf4s7eWs0&feature=related]sandman video[/url] 2012-05-22T05:43:15+02:00 http://area.autodesk.com/forum/autodesk-3ds-max/particles---dynamics/pfsource-particles-flowing-over-a-surface/page-last/ http://area.autodesk.com/forum/autodesk-3ds-max/particles---dynamics/pfsource-particles-flowing-over-a-surface/page-last/#When:05:32:25Z I am trying to get some particle to flow over a lathed cylindrical surface but I am having a problem getting them to behave exactly as I want. I have attached a file which nearly gives me what i want but for some reason there seems to be a small amount of particles going in the opposite direction from the main flow. Basically i just want the particles to flow over the surface of the object from the left hand side and then dissapear just as they reach the end. If i could get this to work it would open up no end of possibilities for me Thanks James 2012-05-22T05:32:25+02:00 http://area.autodesk.com/forum/autodesk-3ds-max/particles---dynamics/particles-vary-width-along-spline/page-last/ http://area.autodesk.com/forum/autodesk-3ds-max/particles---dynamics/particles-vary-width-along-spline/page-last/#When:07:03:25Z I want to have particles travel down a spline and get narrower as they encounter bottlenecks. Picture a tube which narrows. I want the particles to flow with and to narrow with the tube. It's not the individual particle size I want to change, but the width of the stream. I started with position by icon but can't figure out how to vary their width except by scaling the icon. That changes their width from the start, not along the path at a desired point. 2012-05-17T07:03:25+02:00 http://area.autodesk.com/forum/autodesk-3ds-max/particles---dynamics/particle-system-problem/page-last/ http://area.autodesk.com/forum/autodesk-3ds-max/particles---dynamics/particle-system-problem/page-last/#When:04:45:12Z Hi. I have a particle system coming from a shaped emitter. The emit start is set to -250 to enable the correct of particles to be visible at frame 0. All worked fine. When I changed the emitter the particle system started to only emit a few particles at frame 0 building up to the right amount about frame 120? I played about with all the parameters and tried re-creating the particle system but same result? Anyone have any ideas why this has happened?

I wanted the animation to end with an even spread along the spline rather than all of the particles travelling along to the end. Resolution: speed by icon has speed variation controls and setting Min% to zero and Max % to 100 the particles are evenly spread. 2012-05-13T07:07:58+02:00 http://area.autodesk.com/forum/autodesk-3ds-max/particles---dynamics/pflow-speed-by-volume-area-question/page-last/ http://area.autodesk.com/forum/autodesk-3ds-max/particles---dynamics/pflow-speed-by-volume-area-question/page-last/#When:21:37:02Z Hello, What I am trying to do is to have a box container divided into 2 equal sectors. Each sector has particles that bounce according to the area density or properties. One area or sector has liquid density and the other is just air or gas. The gas area particles float at a somewhat fast speed. The ones on the liquid area float slower to mimic higher density due to the liquid. The two sectors with the particles are separated by a geometry wall and when I slide open, both particle will mix depending on their bounce trajectory. So far, I have them working as predicted... The particles from the air hit the liquid area and their speed slow down. They bounce within the liquid area at a slow speed but, when they come back to the gas area, it seems that I cannot have them behave according to the properties so they remain slow. My question is, how do I define area sectors so that the particles know when they are in such, to behave according to the parameters defined? Thank you in advance.

I am working in Max with imported Inventor models containing a lot of detail. I am also using particle systems for liquid flow/fire etc. I will also soon be looking at Max add-ons for heat/flame etc. IT have supplied me with a possible spec for a new machine. Could someone please advise on the suitability/compatibility of the following with heavy Max/particle systems work.
