Hi there
I'm new to animation in Houdini. And i'm just following some simple tutorials about setting keyframes.
Basically i got a ball, in the translate x position of -5, then when i set a keyframe (pressing ALT + LMB) it shows up: 'Bezier ()' in the paramater window of transX. This does not happend all the time, but most of the times.
Animation works sometimes, but only if this does NOT show up.
So instead of getting a motion between the frames, it holds the translate X position until it reach the next frame that contains a key, and then just JUMP to that postion.
why?
