Hello!
I’m having a small issue trying to animate an object that has two sides with joints.  I want to have the animation of one piece of geometry and the other one follows it without intersecting with it. Like two sides of a wave.

I want my C1 and my C2 to be following each other, but I would ideally like to use the same bone animation.  However if I do that they will always be in the same place.  I can’t just offset the bones because it will create weird results…

Thanks!!

Hi Alex,

Backface culling is by default set to on in Unity, to avoid lighting problems:
https://forum.unity.com/threads/backface-culling-in-unity.48919/

The Particle shader has the code to turn it off, but the warning is always (at least in all answers to the question that I found) just don’t do it (paste the code into other shaders).

I’m certainly not a Unity expert, but from what I understand so far, I have done it this way. Switch the Skin object on the mesh off. Copy the mesh with the Skin. Select on the new object all polygons, and reverse the normals.
Switch the Skin object on again. Export as FBX to Unity.

Here is my result, test it before: (c4d/fbx/mp4)

Hi Sassi

Yes, this is what I ended up discovering after some research.  Now we have decided we won’t be transfering animations to Unity, so my question is a bit different…What if I want to have two planes very close to each other bending in the same way with joints?  I there any way to transfer the joint animation with a slight offset to an object that is right below the one I’m animation? I don’t want to have to do the animation twice, so was wondering if some kind of constraint of other option would work…

thanks!!!!

Hi Alex,

Please have a look here: (file and screen-capture)

The procedure usually is to set up one mesh and then switch off the Skin Object, place the mesh as you like to have it, including flipping a Normal , and then set this as the Pose for the Joints. Switch on the Skin Object and done.

Let me know if you have any other question, I’m happy to look into it.

Cheers

Wow Sassi, that’s perfect!  Thanks so much for the super clear explanation.  Great technique.

Thank you!

Thanks a lot, Alex, you’re very welcome.

My best wishes for your project!
