problem with nConstraint - point to surface

[mayunakoki]

I created properly nConstraint - point to surface  for the clothes. But when I put animation to the 3d mode, the robe moves weird. It looks not tighten between body and the robe. How can I fix?

Here is a screen captured video

Hi!

So you have two problems here. The first one is that you start your animation in a pose where the arm is closer to the constrained vertices than the torso, so they stick to the arm. nConstraints are Simulation objects so they recalculate their dependency every time the timeline gets reset.

This can be fixed by simply not directly starting with the animation, as a general rule of thumb when working with cloth you should have about 50-100frames at the beginning of your scene where your character slowly moves from the default position to the posititon where the animation starts. this will still unwanted penetrations and miscalculations, like your nConstraints.

As to the second question, on the nConstraint you should find an Attribute called "Rest lenght scale" decreasing that will pull the constraints in.

Here is a video on nConstraints, what you are looking for is at about 3:30 min:

I hope this helps!

I import FBX animation , so I can't make the 3d model to stand as T-pose. It starts to animation from beginning. I make -50 frame (extra negative frame before animation) , and I want to make it to T-pose, but I can't rotate the whole arm.

I rotated the whole arm, and tried from t_pose. but point to surface doesn't work well
