problem with animating attributes of texture
I’ve got a nasty problem with animating an attribute of a texture (i.c. the Offset U).
Here’s what happens:
I want to make a white area run over an object by animating the Offset U attr. of its texture.
I’ve done that before and reproduced the same keyframes, values etc. to the new situation.
But . . . no animation happens.This is what I do:
– In the Timelinemanager I move the slider to frame 100
– In the attr. manager I set the Offset U value to 16 % and ctrl-click on the black circle next to it; it turns to red.
– A keyframe appears on key 100 in the Timeline.
– I move the slider to 200
– In the attr. manager I set the Offset U value to 36 % and ctrl-click on the yellow circle next to it; it turns to red.
– A keyframe appears on key 200 in the Timeline + a nice sloping spline to indicate the moving texture.
– playing the animation ; nothing to be seen.The strange thing is:
– hovering the mouse above the two keyframes in the Timeline indicates the values 16 and 36 %
– in the attr.manager however, on frame 100, the value of the Offset U is 36 % (the same as on frame 200) and the dot next to it is yellow again.
– apparently the attribute values in the Timeline don’t correspond with the ones in the Attr. manager.I tried to reproduce the same settings as in the earlier project, but there must be something I am overlooking.
Doing exactly the same in a blank document with a simple cube and the same texture > works perfect.
Although it won’t help a lot (I guess) I added a screendump.

Without seeing the scene, it looks like it would depend on the structure of the object and the mapping of the texture. Do you really want U? If it’s a Timeline/AM thing I’d have to see the scene.
