Richey Posted February 26, 2010 Share Posted February 26, 2010 Hi guys, I've got the following problem: I have a train with a lot of wagons - this long train with it's wagons has to follow a path. I know how to do that, the problem is, that the train keeps static. Isn't it possible that Houdini deforms the shape of my train geometry when it's following the path (for example in the curves). That would be fantastic. My idea was to rigg the train and let the rigg follow the path but that wasn't working. I hope someone can help me, I'm very new to Houdini. Thank you! Richey.

pclaes Posted February 26, 2010 Share Posted February 26, 2010 So you want to deform the train as it goes down the path. Sounds more like a deformation than a rigging problem. You want to try putting a lattice around it. But for this you need a "better lattice" as the normal lattice is not kind to rotational deformation. See my first post in this thread for "better lattice" deformers: Quote Link to comment Share on other sites More sharing options...

symek Posted February 27, 2010 Share Posted February 27, 2010 some times ago i made this stuff... I think it's what you want) Path_deformer.hip Nice asset vi_rus! Anyways, shouldn't a train on a rails stay undeformed or I wrongly understand the task? For me it's more like a rigging/procedural animation challange then deforming geometry, since wagons should behave like elements of a chain, right?

Richey Posted February 27, 2010 Author Share Posted February 27, 2010 Hi guys, thank you so far. I think the file/technique vi_rus has posted will work. @SYmek: You're right, the best way would be to rigg the train so that the train will only deform on it's connections between the wagons (rubber). I am new to Houdini and the rigging is no problem for me but I don't know how to connect it logically to a curve. The problem is that I need a solution for my problem not later than tonight and I thought the deformer way would be easier to realize than the rigging way. But if you have a good idead please let me know. Quote Link to comment Share on other sites More sharing options...

Still this asset can help a lot, since you can deform proxy geometry which will serve only for placing "break" points (rubbers) between wagons (which you put after this on rails). I just wasn't sure you talk about the same effect... Quote Link to comment Share on other sites More sharing options...
dbukovec Posted March 1, 2010 Share Posted March 1, 2010 This should be included in default Houdini distribution, nice job vi_rus! Quote Link to comment Share on other sites More sharing options...
