Rigid Body 問題

[kuykuy]

想問下在maya裡用 rigid body, 我個scene 裡面有好多object,
初初頭幾個frame都無問題, 但去到後0的的frame就好慢好慢...
系咪越多object就simulate得慢?
有無方法解決呢個問題呢?

又想問下, 如果個scene有rigid body同無rigid body, render時間會唔會有好大分別呢?(render時佢會唔會再要simulate呢?)

Thanks!

越多 objects 當然會計得越耐, 我地 render 前通常都會 create cache 先. 有左 cache 就唔會每次 run 個 scene 都 simulate 一次, 不過首要條件梗系 confirm 哂個 motion 冇問題啦

水哥真系勁, 咁快有回應

咁即系始終都要simulate一次先, 再想問下出面依家系咪唔會用maya 裡面個dynamic 黎做野? 用real flow?
我個scene都唔系好多rigid body, 五六十個左右, 不過會互相碰撞, 最後跌曬系地下
simulate初期還可以, 但去到中期, 已經想喊, 幾分鍾先得三四個frame, 又唔郁得部機...., 仲要想睇下個motion 0巖唔0巖 , 咁即系唔使做....

都要睇下有咩方法做野先至好0的.....

thanks!

real flow 主要用黎 sim 流體, 而 maya dynamic 仲有好多野都好好用

5-60 個 objects...... 最初未撞梗系快, 越多 objects 撞埋一齊就 sim 得越耐. 每個 object 既 face 同另一個 face collide 就要計數, 你可以試下數一數撞埋一堆時, 有幾多 face 有 collision


p.s. 我依家等緊 render, 所以喺 forum check 得密d 姐

You could try with the Nima plugin for maya. It takes advantage of the PhysX engine which is very fast. You can run the sim through that and then bake out the animation. Another method is to use nCloth to simulate, you can have many objects all running as one nCloth object which speeds the sim by a lot.
