I have a sphere in my scene, and I keyframe its position. However, I later decide to change its position on that keyframe, so I go back to the keyframe in question, and attempt to move the object. I cannot. It seems that Blender will not let me move an object on an existing keyframe. Is there a setting I am missing? Also I cannot adjust it's position between two keyframes to add a new one in the middle. It seems as though setting a keyframe locks it in stone. Any help would be appreciated.
Ok well, I had a dynamic paint modifier on the object. I removed that modifier, and like magic, i could move the object and key it again on the same frame. Looks like it may have just been a bug. I was using a beta version. I switched to the latest stable and I no longer have the problem. :) thanks for your tips
