I finished applying the paint weights to the model last night, and when I brought it into the studio to get it ok'd by my tutor Paul, everything seemed to be going smoothly and moving correctly, untill we came to the feet. I mentioned that I had come across problems weighting the little toe on the inside of the foot, and when paul took a closer look to see what the problem was, he found that it wasnt deforming properly because of two things. One was that there wasnt enough geomatry in the foot, I had forgotten to add an extra edge loop were a joint would be, and two, That the ankle joint was set just above were the ankle was supposed to be, almost halfway between the shin and the knee.
I had spotted this problem before, having mentioed it to several people saying the rig is out side the mesh, but when the joints were sized smaller I unfortunatly forgot about this 'minor' detail untill it was pointed out today. Also the control joints for the foot was slightly out of place aswell.
All this made it nearly impossible for me to use the rig, as it would make walking really awkward when it came to animation. paul said my options were to either call it a day with the model, and move to pre rigged monkey, or I would have to go in and do a bit more remodelling to the feet, make the bottom of the leg fatter to accomadate the ankle joint better, and make sure the joint controls were better lined up. the problem with this is that I would have to re rig the whole model again, aswell as change the model slightly,and go back and exclude all the vertices and paint weight again.
I chose to do the re rigging, as im so close to being able to animate with my own rig. I already have over 80 versions of the whole process saved so it was easy to find the save were I had everything how I wanted before I rigged, I added the edge loops and fattend the ankle, checked and double checked the rig was ok, rigged it, went in and excluded the verts and made sure the joints were functioning correctly. and then to tripple check, paul tested my rig by doing a practise walk cycle to make sure I had a fully functioning foot and was able to get all the poses I needed.
turns out the rig works great. only the toes wont be able to work individually, but as im not picking anything up with the monkeys feet thats ok.
so all I need to do now, Is go back and paint weight. Then I can move onto the facial rig. here are sum pics of what is hopefully my last attempt to rig the body.It takes me half a day to rig my character now.
