I've been testing out the reactor fuction in 3DS Max. And i found that Rigid Body Collection only makes an animation go over like 3seconds. Or only 100 keyframes. Since i want to make longer animations that's kinda annoying, and i have'nt found any way to make longer animations.
Does anyone know about a guide or something about this?
I don't know if this is what your problem is but you can try it out:
Change the global animation time range by clicking on the clock icon to the right of the frame number indicator. (This is on the bottom of the UI and to the right) This will open a window. Select the length of the animation you want and click ok. Now your time scrubber will be the length of time that you set. I believe that this will update your reactor animation length as well.
Yeah, thats the way i've tried to solve it. I asked in another forum yesterday and this guy told me about the utilities menu at the top (the hammer). And some options there. So i solved my problem there :)
