Re: transferring low res syflex to high res geo
Use ICE to get the closest location on your low res (static, undeformed copy) from the high res mesh and store the offset transform from that location. Then use the reinterpret location onto the deformed low res geo.

Re: transferring low res syflex to high res geo
ICE? I'm pretty sure there's either a sample scene or a tutorial floating around online on how to deform one mesh onto another. It's a little late in the day for me to actually work this out, but basically, you'd have a highres mesh with an ICE tree getting position deltas (change from last frame to current frame), interpolated, from the corresponding locations on the low-res mesh. Might want to have matching UV's, but that might not be necessary. I guess really it's a cage deformer running in ICE, but without any kind of static weight binding from one mesh to the other. Or I suppose you could try the old cage deformer, but that's horrible -- slow and inflexible. Or extract a lot of curves from the low-res mesh, plot their shapes, and envelope the high-res to them, if you need something like your current workflow? Or maybe I'm not understanding how complex the geo is, but maybe you could cache the low-res simmed mesh, then extract the poly clusters that correspond to the different parts of the high-res clothing. Then either leave the extractions live or if it's too slow, cache them. Then apply however much subdivision and editing of the geo you need to the cached extracted meshes. Essentially leaving the modeling stack live on top of the low res sim. But that's getting kind of silly, I think. ;-) Ed

Re: transferring low res syflex to high res geo
Thanks Matt...could give that a go too...although I think ICE syflex only works on poly? Eric...good suggestion for a starting point..will try that. I was referring to the default cage deformer...didn't think about hull deformer. I was looking at a few images and demos on syflex's website for the Assassin's Creed trailer. Pretty awesome setup they had with multiple layers of clothing. The ICE Syflex seems much more powerful at first and is definitely faster I think but lacks some of the tools the addon version has like weightmaps. There's another one I'm looking for an answer too. Although I figured if I was able to blend a syflex mesh with a weighted mesh using a weight map in ICE, I'd be set!

Re: transferring low res syflex to high res geo
We would take the high res geo, reduce it, then run a custom script that generated nulls that were cluster constrained to the points on the geometry and simulate it, then envelope those points onto out the high mesh. This was one of our work arounds, depending on the shot and what was needed, but this solution seemed to work pretty well, as long as your create the geometry from a default flat position and then simulate into position. we tried cage deformers on some things, but found the size of the cage deformers to be huge compared to the enveloping. I think each situation calls for different approach. Found that some times you would get great results with one method and then the same method would create horrid results.

Re: transferring low res syflex to high res geo
Thanks Simon...I was using that method as well. It works fine on some other elements but for this one particular case, it was difficult due to the layered fabric. Will give that another go as well. Didn't think about doing a poly reduction, keeping it live and using that as my null deformer group...might be more manageable.

RE: transferring low res syflex to high res geo
EDIT: Surface constrain the nulls to the NURBS surface, not to the control points. This would allow you to drive the orientation of the nulls as well as translation.

I would surface constrain the mesh to a NURBS surface of similar size/shape, and run Syflex on the NURBS surface. When you're testing the simulation, you can hide the mesh to get the performance. When the simulation is to your liking, unhide the mesh to check the results. When you have something you really like, you can optionally plot the results as shape animation onto the polygon mesh. If you prefer, you can also plot out as envelope animation by making a bunch of nulls to act as deformers of your polygon mesh, and then constrain them to the control points of the NURBS surface. Plot transforms for the nulls whenever you feel the results are to your liking. If you want multiple 'takes' to choose from, you can plot to a mixer source instead of directly to the Transform parameters as FCurves. You can then play with the mixer sources to further massage into a result you like. This would give you a lot of freedom and quick iteration.

RE: transferring low res syflex to high res geo
As a user my main worry would be editing one of the mesh topologies would unexpectedly cause some nulls to change orientation because the reference frame changes. A safer approach would be to create a smooth and continuous coordinate space and align the nulls using that data. If the mesh topology is edited, the nulls won't have the rug unexpectedly pulled out from underneath. Nvidia has sample code to compute such a space for normal maps (NvMeshMender?). The code could be modified to output a coordinate space as a weightmap, vertex color, UVspace, userdatablob, or whatever suits the purpose.

Re: transferring low res syflex to high res geo
Maybe I'm missing something here, because the solutions are rather complex hehe so please bear with me if I'm totally out of context. Here's a little video showing how my first suggestion works. The smoothing part, well, that's up to you, I was just playing around, but who knows, maybe it works for you... http://www.screencast.com/t/jZIJ3L3lEDPc Orlando.

Re: transferring low res syflex to high res geo
Why are we even talking at all when Leonard pointed out there's a factory node doing exactly what is being asked for? :p
Re: transferring low res syflex to high res geo
That is not a factory node. I have built similar systems in the past. So it didn't take me too long to make a proper compound for this.

RE: transferring low res syflex to high res geo
You suggested using a reference frame. I merely pointed out a potential trouble spot.

Re: transferring low res syflex to high res geo
Oh ok, thought I was just behind on features (haven't used syflex since Sucker Punch).

And merry Christmas to you too Leonard, I have a scenario that this compound will find usage in right this morning. Thanks for sharing!
