Re: Continued use of Softimage question
Pretty sure that applies also to Mantra renders. But, most places have a smaller pool of engine licenses and export all frames to .ass or .ifd for rendering.

Re: Very OT: for the love of your career.. try houdini
Network and hardware are fastest I've used. It's just the nature of the work. Volume data in my case is not very large, only a few Mb per frame. But, e.g. to make useful collision fields from complex geometry often requires a good bit of SOPs pre-processing. I get the impression that much of SOPs is still not especially multithreaded. DOPs is also very slow vs solvers of comparable classes (FumeFX, Exocortex's Bullet, nCloth). But, that's generally OK since you can do so much, much more with DOPs with a very low chance of things failing apart as you scale up.

Re: Difference between ID to Location and Point Index To Location
Particle ID is unique, but point index is not. For example, when you delete some particles, their ID is removed from the set, but the point indices will be shifted. So for any particle ID, its index could change from one frame to the next. You might have an occasion when you want to grab an ordered set of locations from a pointcloud, but if there are gaps in the set of IDs, then you can use the point indices as a reliable lookup. So, you can probably think of a few more examples when one or the other would be more useful...

Re: ICE: Raycast against instanced geo?
I'd be interested if sending the geometry back and forth to CP (Splice, I guess?) would be any faster than doing the work directly in ICE - assuming the work can actually be done in ICE. On Tue, Oct 1, 2013 at 5:10 PM, Mathieu Leclaire mlecl...@hybride.comwrote: It can be very tricky to do. The easiest way would be to convert your instances into mesh. There are various ways to do that. ICE modeling or Momentum's instancer are possible ways but if your instance master have hierarchies, you probably will need to merge them so that it's only one object. The down side to this technique is that converting instances to meshes can make a very large mesh depending on the complexity of your scene. There are other ways you can proceed but they all require some very advance and complex implementations. You can raycast on the instance masters by multiplying the ray origin and direction by the reverse of the particle matrix, but you'll need to figure out a way to select which particles to raycast on first as you don't necessarily want to test all of them. And if you have more then one instance master, you're going to have to separate each master in your ice tree or line them up so they don't intersect and decal the origin accordingly. It can become very complex very fast. Another idea is to use a tool like Creation Platform or Arnold to do the ray tracing for you and return the proper information through a custom ICE node or something, but that's another very complicated approach to implement. Hopefully something like Momentum's instancer will be good enough for you. If converting your instances to mesh is not feasible on your machine, then I'm afraid there's no easy solution. -Mathieu -Original Message- Subject: ICE: Raycast against instanced geo?

Re: Looking for exporting tips with ICE topology - SI2014
Yeah, in your example scene, you've created a texture projection on your copy geometry and you're attempting to write the UVs that.

In ICE, you can pull an attribute from a node context and write it back to a UV property, but I wouldn't exactly say it's a stable or recommended workflow.

You can further refine this with a force field approach, run a distance from hull (closest location on geo), and if the point is close enough to a location with a normal facing away from its distance vector remove it, and remove anything within a certain threshold (very close) indiscriminately. Testing against denser geometry also helps, even if it's more expensive, sparse and variedly populated topology tends to introduce more room for error.

It can be very useful if you do the skinning in a package and the rigging in an other one.

So to keep things simple, why not considering your asset as a zip archive on disk, in which you may use different file formats to store datas depending on the type of the asset and the application it's most often used in. Bundled with the archive, add it a json/xml/whatever file used to store the metadatas (creator, ctime, asset-type, ...) It becomes easy then when an asset is wanted to retrieve the adequat file (if exists) or run a converter (if needed). This allows you to keep application-specific file formats while not having trade-offs on their re-use in others by abstracting. Your asset manager don't know about the files but only about assets.

The Rig/Sim assets will be native emdl as they are only going to be used in softimage (though I have my issues there too...). A few things my exporter is doing are * exporting MatLib with all materials * exporting ColladaXML * exporting/converting images to exr (via OIIO) * parse MatLib and fix the filepaths for the textures (pointing at asset location) Big plus for using Collada * will work with most applications * can be used in Softimage as Reference * xml based Big plus for FBX * will work with most applications Big Minus for FBX * can NOT be used in Softimage as Reference * not a xml format (need to make your own parser) Big Minus for dotXSI * tends to crash other applications when importing dotXSI Big Minus for emdl * binary, impossible to edit So all of the above points towards Collada, but what do you guys think?

Re: flood simulation
Hi, so it's pretty simple after all to have interesting interaction between RBDs and Lagoa simulations: https://vimeo.com/51754990. But, if you have a bunch of objects in your scene that need to interact with the fluid, you'll need to instance them to a pointcloud - not such a big deal most of the time. There is a small bug with this setup, if you remove members from the ICE topology group, it may crash. Safer just to make a new group. So as far as I see it the problem is not really interaction with the fluids, that's easy. The problem is more like scalability. If you want a huge, end of the world type of flood then Lagoa won't scale too well at all. Realflow is probably the best commercial solution for massive simulations right now. But, if you're just flooding the bathroom, then Lagoa may well do the job! Ciaran p.s. I miss you Naiad.

El 10/18/2012 6:34 PM, Mathieu Leclaire escribió: This is not an easy task to accomplish in Softimage, but it is doable. I see two possible avenue I would explore: 1 - What I would try with Lagoa is emitting elastic particles for your rigid objects and make the elasticity very stiff. Make sure they have an ID based on the emitted mesh and a transformation relative to that emitter. Then, at every iteration, I'd figure out a way to average these particles transforms by ID to create a transform for the rigid particle group that I would apply to the rigid object. So the particle group (by ID) moves the mesh. Once you get that average tranform, I would overwrite these elastic particle positions by multiplying their saved relative transform by that new average transform and basically bring them back into a rest state. That'll avoid the rigid mass of particle to deform by their elastic properties and will allow proper collision for the liquid particles. You are forcing particle positions so it might insert some instabilities in the simulation, but I think it should work. So to recap, you let the elastic group deform and interact with the liquid group in one iteration. Then you undeform the elastic group by their averages to bring them back to a stable state as if it where actually rigid. You then simply match the transform of your rigid objects to that of it's relative group average transform and you keep iterating. That's one way. 2 - A second way would be by mixing Lagoa and Momentum. You would simply simulate the liquid by Lagoa with your Rigid Body meshes as collision object. So you would need a Deform Bodie with ICE controls, and your ICE controls would sample the closest Lagoa particles and create a force based on their average velocities. I think that would be doable as well. I haven't tried any of these techniques myself, but that's where I would start experimenting. Now if you need to do a big flood, you will probably need a lot of particles to have a nice looking simulation. I hope you have a good machine with a lot of memory and a lot of patience. Lagoa is best suited for smaller scale simulation. It's not the best for large scale liquid simulations. I would look into Houdini or Naiad (if it's still available after Autodesk bought them) for better and quicker results. Maybe even Realflow could be a better option. But if staying inside Softimage is a must, I would explore these two suggestions. Good luck! Your going to need it. -Mathieu Pablo Tufaro wrote: Well, that may work...!

I have to mention though, that I did not mean the spread control on the light... there is also a falloff control, which is achieved by clicking on the circle at the cone terminus. -e I understand how to change the spread, but it doesn't seem to give predictable or nice falloffs. I've been playing with settings since I wrote that and I wonder if it's related to Color Management. I'm interpreting my source textures as sRGB since they are just jpeg's. I have Color Management turned on for Regions. When I turn it off, the light falloff is much more smooth and closer to what I want, however, the gamma is way off since it's showing the linear image I'm assuming. I have been rendering without Color Management on my passes and interpreting them as linear in After Effects. I'm not sure how to get the falloff looking better though since I can't very well ignore the gamma issues.

Then you just click and drag the edges to change the spot softness. I can't check right now but I think its the b key. Actually pretty nice feature. -e On Thu, 2012-09-27 at 23:05 -0400, Byron Nash wrote: This seems basic but it has always confounded me. I would like a softer fade from the center of my spot light to the outside of the cone angle. Adjusting the spread seems to make little difference. See the linked photo for an illustration. I don't understand why the falloff does not start at the inner ring of the cone and fade to the outer edge? There seems to be a limit to the amount of softness I can get out of a light. What am I doing wrong? https://dl.dropbox.com/u/6776444/coneAngle.png -- - Ciaran

It's still quite a niche. So, if AD continues to diminish all those years of work we've put in, the vast majority of us are still up the creek without a paddle. Unless of course you don't mind the idea of working with Maya all day. I do.
Re: nulls2mesh
Sounds like you want a convex hull of the null's points. Pretty sure there was a compound once, if not you might try Mr. LaForge's Convex Hullhttp://frenchdog.wordpress.com/2012/01/05/happy-2012/ICE node.

Re: ICE Deform: Rotate polygons
Hi, the easiest way to deal with this type of thing is indeed using matrices, but you need a local matrix per polygon. You can get a 3x3 matrix using Self.polygonreferenceframe. You're going to want to zero-out this matrix (it just describes the local axis of the polygon), but matrix multiplying the pointpositions by the inverted poly reference frame. Now you can do your rotations (rotate vector) in the familiar local space of the object since the polygon is now aligned to local space. When you're done rotating the points, simply re-multiply them by the polygon reference frame, to put them back into the correct space of the polygon.

One by one, I want the polygons to rotate 180 degrees so that the polygon normals point upwards. This is part of an animation, so the rotation must be gradual. And I can't just rotate around some global axis because the road has curves and turns.

Its not as insane as it sounds. i would suggest creating two nulls, get there globla kinematics(Matrix) then do a invert on the one matrix(A) and multiply it by the other Matrix(B), and pipe that back into the global kinematics. That would give you a better understanding or matrix's and there space, and then you can mess around with the rotations of the local matrix. Hope that helps, also im not 100% sure what kind of rotation effect your trying to achieve?
