objects or, if that's not possible or desirable, create a copy or snapshot of the
bodies and make sure that a suitable controller is assigned to the snapshot
copies. Use these copies for the reactor simulation instead.
Rigid bodies in animation flicker and jump when playing the animation
but not when moving the time slider.
This is usually a problem with the subframe interpolation of the Euler (XYZ)
rotation controller. While reactor sends valid transformation keys to the
controller, the conversion from an arbitrary rotation to X,Y and Z Euler angles
may cause non-smooth animations between keyframes (the controller produces
noncontinuous X,Y and Z values). This problem can be solved by using a
quaternion-based rotation controller, such as the TCB controller, for the rigid
bodies.
Preview Animation fails
While the
Preview Window on page 4099 should work with most OpenGL and
DirectX compliant hardware, some specific hardware and driver configurations
might cause problems:
■ Update to the latest drivers for your graphics card. Refer to the
manufacturer's Web site for details.
■ Try to use DirectX instead of OpenGL (or vice versa) for the preview. This
setting, independent of what is used for the 3ds Max viewports, can be
changed on the
Display rollout on page 4093. If you discover that your card
works only with a particular configuration, you may want to create startup
script (a script in the scripts/startup folder) that calls
reactor.displayUsingDirectX = true/false.
■ Some problems can be caused by lack of display memory. Avoid having
multiple sessions of 3ds Max open at the same time, and reduce the size
of the windows and the display resolution.
■ Try changing the 3ds Max to different drivers: OpenGL, Direct3D or
Software.
Wind doesn't seem to work
■ Make sure the Wind Helper icon is pointing towards the right direction.
■ If the wind should act upon cloth, rigid bodies, etc., make sure the correct
check box is on in the Wind Helper parameters.
