1、rayfire中文帮助simulation tab 1.1 impact objects in this rollout you can define impact objects.impact objectsimpact objects are geometry objects which you want to simulate, shoot, fragment, explode or demolish. you can use animated impact objects, in this case reactor or physx will take initial velocity

2、 of objects at simulation start frame and continue it. so if you want to throw objects start simulation at the middle of objects animation. pay attention that every time when you fragment, shoot or demolish impact objects, rayfire creates copies of impact objects, hides original objects and use copi

3、es for simulation. when you delete simulation layer via interactive layer manger, rayfire deletes objects from selected layer and unhides original objects. if you dont need in original impact objects, you can delete them picking delete all original objects in tools menu.working with listseach list i

4、n the rayfire tool has three buttons: add, clear and menu.add : to add some objects to the list, you must first select the objects in the viewport, then left-click the add button. right-click the add button to open the selection floater window to select objects inside floater. clear : you can clear

5、list by left-clicking clear button. in case you want to remove only one object from the list you must select the object in list and right-click the clear button. pay attention that you can selecte several objects in list holdin control button before remove them from list using left click. menu : lef

6、t-click the menu button to open the menu list. selecting select all will select in vewport all objects in list, selecting select highlighted will select in vewport only objects selected in list. selecting highlight will select in list objects selected in vewport. interactive selection : interactive

7、selection available only for impact objects list.every time when you want to exlode, fragment or simulate some objects you have to add these objects in impact objects list.in some cases such workflow might speed down you workflow. turn on interactive selection and after that rayfire will update impa

11、的、产生碎片、或是爆破的物体，你也可以使用带有动画属性的碰撞物当你每次使用impact object去模拟的时候。rf（rayfire）都会把你所添加的impact 物体复制一个副本去模拟，而把原始的隐藏起来。当你在交互式层管理器中把该层删掉的时候，rf又会把impact 物体副本给删除，把原始的显示出来，如果你不需要原始物体的时候。，你可以点击tool目录下的delete all original删掉原始的物体working with lists在rf 工具中的每个列表都有3个按钮 add clear menuadd : 把物体添加进列表，你必须先在视口中先选择物体，再左键点击add。你也可

12、以先右键点击add，这时会弹出max的浮动选择面板让你选择你需要添加的物体clear : 左键点击删除列表中所以的物体，右键点击只删除列表中高亮显示的物体. menu : 使用右键点击会打开memu菜单simulation tab1.3 shooting options （射击选项）在这个卷展栏中你能控制模拟射击的所有效果gun objects（枪物体）枪物体使用正z轴对碰撞物发生影响，你可以为枪物体创建一个动画，你也能在tool 菜单下点create gun来快速创建一个枪物体。shooting options（射击选项）start frame : 第一枪的帧数，它不能少于5帧。end fr

13、ame : 最后一枪的帧数。shooting rate : 每一枪的间隔帧数rounds per shot : 每一次射击的子弹数spread angle :每一枪最大的随机角度simulate shooting (射击模拟)执行射击模拟计算，确信你至少添加一个枪物体和碰撞物体，并打开至少一个射击效果，否则你看不到任何效果当你使用reactor hit, displace, holes - realtime or holes predefined模式式, rayfire 将把所有的碰撞物体复制一个副本并添加到碰撞列表中, 并把原始的碰撞物隐藏起来. 模拟时rayfire只对这些碰撞副本进行计算

14、，对原始的不进行任何修改。instant action使用这个按钮你能手动添加射击效果和碰撞变形。 选择你需要的效果，并把碰撞物添加到列表中，当你按下这个按钮时你就可以在碰撞物体上手动的添加添加射击效果和碰撞变形。注意: 如果你使用碰撞变形模式，请先保存场景，instant action会直接在你的原始碰撞物上产生效果geometry （几何体效果）ecals :创建一个使用平面来模拟的子弹坑效果。bullets :创建一个自发光的长方体做为子弹。reactor debris : references : 在debris卷展栏中添加一个碎片参考物并参与reactor动力学计算。eactor d

19、ctor 在每个模拟步骤中执行的任务之一就是检测场景中的对象是否发生碰撞，然后相应地更新场景。如果对象的距离小于“collision tolerance”值，则 reactor 会将其看作对象碰撞。如果“collision tolerance”值较高，会使模拟稳定，不过，也可能会造成“碰撞”对象之间出现缝隙。substeps : 定义物理计算的子帧步伐，建议保持在15之间，更高的值会得到精确的计算但同时减慢运算速度gravity :默认重力的倍增值preview and create animation buttons : 预览并创建动画override properties : 当启用时,
