Objects intersect after placement
Ok, this has only happened once or twice and I usually manually move the objects I have placed. I have multiple objects...active rigids, made a glass as passive rigid. Connected a gravity field to the active objects and hit play, when they rest some of them are intersecting with the glass object....any ideas. I would have thought it works without hitch....alas Maya loves me...not.

cheers bullet

Im using the same divisions as in the tutorial dave.....and the tut doesnt seem to have the same problem....which is wierd. I guess I could make a copy and divide it then move the selection to the original...it doesnt need high poly.

cheers bullet

Bullet mate what version of Maya are your using? I think I know the tutorial your doing and there is a better way of doing it, if you have Maya 2009 or higher I'll record you a small addendum tutorial this afternoon.

I will do part 3 tomorrow man I beat....I have worked out (I know jumping ahead...sigh) that tweaking the bounciness on the plane AND the glass stops the rings from flying out too fast. I WILL watch part 3 for the difference between static and dynamic friction....so Im not jumping ahead LOL (naughty man I am). I am currently tipping over a cup (its all I have in my prison room)...with coins in it to study the way they move....

cheers bullet

Glad you worked it out mate. I believe the attribute spreadsheet editor is in that tutorial somewhere which can be a lifesaver if your working with many objects. You can also swap the ridged body objects for nCloth objects for soft body dynamics or simply as the nSolver is better than the one used in Maya's ridged body sims.

Sweet as mate...I just LOVE dynamics mate....gives the brain a workout and I feel more involved than just modelling. Cheers for the help mate

Here you go I knocked this up with nCloth acting as the rigid bodies

test1800 - YouTube

You'll see intersecting geo because I have the quality of self collisions set way way down. Did not want to spend to long simulating this bugger.

BTW the sphere that crashes through the wall has no dynamic proprieties whatsoever it's not a passive colder. The wall itself is an ncloth object and it's the only dynamic object in the scene lol just to mess with your head a bit

Thanks I'm in the process of re-creating this in collaboration with Jay

Lighthouses and waves during VERY stormy weather - YouTube

It's a large project as you can imagine. I'd also love to do something with the RIM launcher you sent me as it's a very nice model I just have not had the chance yet. But hopefully I'll do it justice.

Dave

LOL thanks for the bullet one David, you do realise now you have piqued my interest I will work out how you did it ....glass looks nicer with a darker background mate. As for the lighthouse...good luck...that would be awesome to see!!! I have a photo framed of the firts one I think in my house...cost me a bit too. Has a dude standing in the doorway with a HUGE wave breaking around the lighthouse.....awesome stuff. Would be scary to be there, though I would love it!

cheers bullet
