Need help with Discreet Char Rigging tutorials!

[valoukh]

It has just come to me that the second problem is probably linked to the fact that the foot is going through the floor!I read somewhere that this could be caused by the user missing out one of the instructions in the tutorial (perhaps one which locks the foot on the floor-level?), but, as I'm pretty sure in myself that I followed the tutorial correctly, I'm finding it difficult to pick out the thing which I (may) have missed. Has anyone any idea what might be needed to stop this from happening? As far as I'm aware, I've made all the necessary connections (in wires and links), and my limited knowledge of rigging is preventing me from being able to diagnose the situation! I loaded up the tutorial file with this leg setup, and, when the foot is rolled forward, everything works perfectly.

I've only just realised how serious a problem this is - surely one can't animate a character if the foot goes through the floor whenever it rolls forward! I wonder, then, does anyone know what link (or wire) might be missing? And would it be possible to make this link now, or would I have to start the entire rig again? I'm simply not sure as to what extent the rig can be changed once it's been created.

Thanks again,

These days I am reading these same Max Tutorials. I had no problem with
this Legs and Feet Tutorial. So I think I can help you. But I need examine your file.
So, send me the file you rigged what have the problem to my email:
jmbbao2(at)terra.es (use the correct arroba sign instead "at" of course)
Because you and me are reading the same tutorials I think we can help
one to another. I hope so.

Un saludo desde España :).

ok, you somehow adjusted the pivot or you rotated the bones. in which viewport did you created the bones ? recreate them in the left viewport, then it should work.

to see that something went wrong, create another leg in the left viewport and apply a hi-solver from the upperleg to the ankle and activate the select and manipulate tool (next to the snap tools). you will see that your swivel manipulator is facing to the back of the leg, thats why it snaps to the back when you assign the swivel target. if you create the legs in the left vwport, you shouldnt have this problem. i cant tell you a quick way to fix this in your setup, so just create the legs agian, takes 5 minutes ;)

1) Knee Control:
Your bones have local X and Y axis correct BUT Z axis mirrored !!!
Double click on bone_leg_upper, choose Local for coordinate system
and choose the mirror tool.
Choose Mirror axis: Z only and Clone Selection: No Clone.
Now the knee control works.

2) You have wrong the wire for
footLCTRL > Modified Object > Attribute Holder > Custom_Attributes > Roll
-->
heelRotateLHELP > Transform > Rotation > X Rotation

you have: degToRad (0.6*Roll)

when in Tutorial it says: if (Roll < 0) then degToRad (0.6*Roll); else 0.0

3) In these Tutorials they say we must ZEROing the controllers we create. This
is a cumbersome task (create a helper, and intercalate it in the hierarchy), so I have created an script. I select all the controls I want ZEROing with HELPERS and push a button for create all the HELPERS correctly situated in the hierarchy.
See next post below. :)

[Bao2]

Copy this code to a text file and then rename the file to "BaoZEROHelper 1.0.ms"
Place this file in Max/scripts folder. To run, in Utilities panel select Maxscript and
Run Script and select the BaoZEROHelper 1.0.ms file. Now in the dropdown list
appears this script but for run it you must open the dropdown and select again. Now
scroll down the utilities and next appears my script. It has three buttons: create,
delete all and delete selected.
Create: You select control objects and next push this button to create HELPERS
with the wireframe color you choose
Delete All: Delete all the helpers
Delete Sel: You can select all the objects in leg right for example and only the
ZEROing Helpers will be deleted.

You can create three boxes and link the three in hierarchy and test my script.


/* BaoZEROHelper 1.0
Create Helpers (displayed as a centermarker) for the selected objects with the same name
and appendix "_ZERO". Inserts the Helper in the Hierarchy as parent of the selected object.
So, we are zeroing the trackview curves for the selected objects.

Delete All Helpers delete all objects in the scene with "_ZERO" in its name.

Delete Selected deletes objects selected only if have "_ZERO" in its name.

If you are reading the rigging tutorials I think you appreciate this. :thumbsup:

[olli96]

btw, instead of adding more nodes in your rig to zero-out the controls, you could use the freeze transform (alt+rmb) function. ;)

Yes. Yours is a more "modern" way. :thumbsup:
