johnl3d Posted December 29, 2004 Share Posted December 29, 2004 threw this together tonight ~1/2 hour ..someone wanted to have a rock hit some snow going downhill as in 3d mag/lightwave...I haven't really looked at it just glanced and tried this idea its rigid body on a rock, cloth rut and a few sprites for now as time allows i'll try other ideas ..open for suggestions also got a bad cold so this is all i have time for I think it was Paul ..new user I believe snowball.mov Quote Link to comment Share on other sites More sharing options...
paulmcg1 Posted December 29, 2004 Share Posted December 29, 2004 Wow John! This is awsome. Now is there a way to get the rock to make the indents on the surface? The surface looks like its jiggly. This is awsome john keep up the good work! Paul Quote Link to comment Share on other sites More sharing options...

Malaclypse235 Posted December 29, 2004 Share Posted December 29, 2004 I have to agree. That looks really cool! Mal Quote Link to comment Share on other sites More sharing options...
Zaryin Posted December 29, 2004 Share Posted December 29, 2004 Maybe, instead of cloth, you could use and animated displacement map. It's looking great so far. Quote Link to comment Share on other sites More sharing options...
johnl3d Posted December 30, 2004 Author Share Posted December 30, 2004 animated displacement could be the next step but since it was late and i had not tried cloth for a while i just threw that together. or instead of animated displacement a series of bones controlled with a % pose slider like i did for a few other things. I used the cloth mostly because it would give the snow bounce when it animated but that could also be controlled by poses for those who want attempt something similar the first step is make a "mountain side" make another model for the rock. place the rock above the the slope in the chor then add rigid body constraint to the rock and then simulate... the rock will bounce down the surface and by adjust the bounce etc you can get a good rolling rock. the rest can be done some of the ways mentioned here plus adding the sprites for snow. will post something more as time allows Quote Link to comment Share on other sites More sharing options...
paulmcg1 Posted December 30, 2004 Share Posted December 30, 2004 Maybe, instead of cloth, you could use and animated displacement map. It's looking great so far. Yea in the magazine of 3d World I think it was issue 58 or something like that...They used displacement maps for the indents of the ground so when the rock hit the ground it would only make the ground go in where the rock hit and it would stay that way.

johnl3d Posted December 30, 2004 Author Share Posted December 30, 2004 had a few minutes so i tried to animated the trench by hand in the chor add the sprites but not the timing etc really rough snowball1.mov Quote Link to comment Share on other sites More sharing options...
Zaryin Posted December 30, 2004 Share Posted December 30, 2004 The timing is a little off, like you said, but it is going to look pretty good when you get it down. Quote Link to comment Share on other sites More sharing options...
Hutch Posted December 30, 2004 Share Posted December 30, 2004 The rock seems to be spinning backward at first but I think you are on the right track with hand animating the trench. Quote Link to comment Share on other sites More sharing options...
johnl3d Posted December 31, 2004 Author Share Posted December 31, 2004 Okay i did one more try the rest is up to the next volunteer .. I have one model which is the hill and the rock I used a pose slider to position the rock and deform the hill..the timing is pretty close but ...anyway i then had some sprite snow turn on and off in the chor by adjusting the emission rate when the time seemed right snowball3.mov Quote Link to comment Share on other sites More sharing options...
johnl3d Posted December 31, 2004 Author Share Posted December 31, 2004 So anyway ....here is the project file the sprite is the spots on the cd ..data materials particles sprites I'll answer any question but I got other stuff I have to work on Hope this helps Paul ...Hey Jeff you can tweak it now (Jeff lives near by) Good Night and Happy New Year Johnl ..3d oh I use 11.1 the latest snowball3.prj Quote Link to comment Share on other sites More sharing options...
paulmcg1 Posted December 31, 2004 Share Posted December 31, 2004 Thank you so much John for helping me figure this one out . The last test you did nailed it right on the head. Thanks so much! There is so much you can do with this now. Im gonna work with what you left us and see what I can do. Maybe I can make a scene of a huge rock falling off a cliff into a pile of snow . Ahhh well thanks again John this is really what I was looking for . Paul Quote Link to comment Share on other sites More sharing options...
Zaryin Posted December 31, 2004 Share Posted December 31, 2004 LOL!!! That has got to be my favorite so far, John. You seem to be completing these things more and more. Great Job, it's perfect. Quote Link to comment Share on other sites More sharing options...
johnl3d Posted January 1, 2005 Author Share Posted January 1, 2005 this is not really complete but I hope it gives you a way to proceed. I should have used some bones on the trench segment to get better control of the depression. Hopefully the rough project will still be helpful .
