Softimage to Unity

Softimage to Unity Working Workflow:

• Do your own rig.

• Created several nulls (shadow rig), a null for each character's bone and put the match as rotation and translation, turn on constraint compensation, constraint pose.

• Envelope using the shadow rig.

• Use the controllers of the original rig to make the animation.

• Middle click shadow rig.

• Click Select, Select Child Nodes.

• Tools, Plot, All Transformations.

• Check box for Enable "Fit plotted values whith an fcurve". OK.

• Constraints, Remove All Constraints.

• Make sure that the pivots are in the right place.

• Middle click shadow rig and character mesh (select both).

• Export, FBX, Select Remove Camera and Lights.

There are some posts about it, but rolled all the problems together in a single post to not only solve my problems but also to help others.

I am facing two problems ..

1 - Export the char with animation.

For the first problem I kind of figured out how to fix, you simply must do a shadow rig linked to its original rig, to when exporting not have problems with other software.

I found these tutorials on how to do this shadow rig:

It's for unreal engine, but the logic is the same...

By the logic goes like this:

I do all the rig with controls and constraints,

Then do the shadow rig, using nulls (read that is better, it is cleaner)

Use constraint match rotation and translation by placing each null in each bone,

Then do the envelope using only the nulls,

Then I do the animation using the controllers of the original rig and it's just plot the animation to the shadow rig.

I have some questions:

How do I plot the animation in the shadow rig? Do I put the shadow rig inside the character model and export it all or export it separately but in the same fbx?

I've found an workflow posted in another post by blure007:

Here is our current workflow for characters from Softimage to Unity. Pulling this from memory so bear with me

Animate, Create, Character, Biped Guide Default Settings Align guide to character Create, Character, Rig from Biped Guide Shadow Rig Tab select SI|3D Delete Biped Guide Select Character Deform, Envelope, Set Envlope, Yes Pick entire root Shadow Rig Weightmap and Animate Character Middle Click Shadow Biped Click Select, Select Child Nodes Tools, Plot, All Transformations Check box for Enable Fit Plotted Values Select Shadow Rig and Select, Select Child nodes, Remove constraints on Shadow Rig Lower spine and next, CRTL+R and change IK to FK blending Export, FBX, Select Remove Camera and Lights

2 - When I export to FBX, symmetrical texture map is wrong.

For the second problem, I found a guy who had the same problem, except that he fix it, but he did not share.

http://forum.unity3d.com/threads/82779-texture-problem-with-softimage-Symmetrical-model

I need when the FBX export, it is arranged with the texture (or the UV OK) and working animation.

OBS: When I import the FBX to the Softimage, the symmetry map is wrong too.. So it seems that the problem is in Softimage.

I found a reply to this problem in a post by SKSFennec...

Triangulate the model 2. FreezeM 3. Quadragulate the model - Not necessary for import but I like seeing my models clean.

Thanks in advance.
