I've got a traps (modeled a single mesh to span both scapula and torso part) with two fibres painted for each section and two curves + LOAs.
Both fibres work well when excited manually.
But when adding a LOA I'm only getting a result on the long fibre, not the short one (see image).
The curve for the short one is positioned to produce good length reduction on the pictured head back pose, so I'm not sure why the LOA doesn't cause any excitatoin.
I've tried raising pos sens. to 5 and 10 even. No change.
There is no way to reset the rest length of a LOA, is there? I did reposition the curve, but also rebuilt the LOA afterwards, because I figured it may get confused if I didn't rebuild it. But still, it doesn't seem to work.
Material is standard on the muscle.
Woa, found it. It was the excitation exponent. It had it set to 105 to try and get more of an effect. But for some reason that led to fibre drawing staying red, as if not excited, which led me to believe it's not working but it looks like it was just the drawing that wasn't right.
When I set the exp to 103 I do get the expected yellow color.
mzeller Ah, I see.
The fiber is colored based on a relative, not an absolute value.
The ceiling of the gradient is defined by the maximum strength of the fiber (defined on the zFiber node)
This can lead to situations like this one, where the muscle is contracting, but it is hard to see a color change because the maximum strength is beyond the range of the excitation.
