Timeline interpolation behaves strangely

dingzhongmingmax

I am using Daz 4.12, and encounted a strange problem when making animation in timeline.

Sometimes I set the neck's bend angle to 10° at frame 100 as keyframe, and keep the bend angle at 10° at frame 110 as keyframe.

I support from the neck's bend angle will keep 10° from frame 100 to frame 110.

However the angle keeps changing to 10.3°, 10.5°, 10.8°, 11°, 10.7°, 10.4°, ... then back to 10°

How could this unintentioned interpolation happens?

By default DS uses smooth interpolation (TCB) so it is effectively drawing a curve through the keys - to go from 0 to 10 to 10 the curve, in order to be smooth, will hump up above 10 between the two keys you set. You need to use the dope sheet/graph sections of the Timeline to see the effect and make adjustments to the TCB values or the interpolation type to change this.
