dealing with bending

hello guys, this might be a frequent problem …i modeled a character and it’s armature i rigged all bones to the parts
and started trying weight painting and assigning vertices but still not accurate enough and have distortions when i move or bend the parts (elbow, knee and hip area especially)
i looked online for tutorialshttp://cdncache-a.akamaihd.net/items/it/img/arrow-10x10.png but i didn’t see what i want so if anyone knows a trick or something to help pleasehttp://cdncache-a.akamaihd.net/items/it/img/arrow-10x10.png let me know
i attachedhttp://cdncache-a.akamaihd.net/items/it/img/arrow-10x10.png the file i’m working on

Your rig don’t have proper parenting chain; arm bones needs to be a child of “upper body” bone and “upper leg” bones needs to be a child of “lower body” bone. Try to fix that fist.

You also will need a Root Bone… (Master Bone) that is the parent of all your Bones…
a bone that you can grab and move the whole Armature by…
A Lord of the Rings Bone…
One Bone to Rule them all…

sorry i uploaded the early saved file i meant to upload another one, i edited the file tho so you can download it now …i already did all the parenting and the bone that control the whole armature… my main problem is with the elbows and knees, they look terrible when thy bend and i don’t know how to make them look smoother. i tried adding vertices, subtracting them, giving them light wight and heavy weight …nothing is working Y_Y, or more likely i am not using them properly that’s why i’m asking for help

to make your Rigging life easier…
do these things…

Turn on Xray (which you already have) but also in that same Display panel select the “Maximum Draw Type” from “Textured” to “Wire”

also with your Armature selected and in the Properties Panel Object Data (little man Icon) under “Display” check the box next to ‘Axes’…
this will turn on the axis visibility for all your bones…
very important for solving problems with your rigg later down the road…

on your bones and elbows I suggest these changes…

Parent your Elbow IK targets to the Chest bone (Upper body)

Parent the Knee IK targets to their respective LegControl bone… such that when the foot moves the IK target goes along with them…

Next select the LowerArm bone… > goto the Properties Panel > Bone (the Bone Icon) > find the Inverse Kinematics Panel > set the Locks for the Y and Z axis leaving only the X axis as the axis the elbow joint can rotate on…
I would then goto the Bone Constraints Panel and set my Pole Angle to something like… 80*
do this for both arms…

goto your Lower Leg bone and do the same thing as you did for your Arms…
Properties Panel > Bone > IK panel > lock off X and Y … leaving Z as your rotation axis…
note how you can see which axis you need to rotate by having the “axis” display turned on…
then…
adjust your Knee target angle in bone constraints if it needs it…

finally Select your Character Mesh… > Under the Properties Panel > Modifiers(the wrench Icon) > Move your Armature Modifier up in the Stack so it sits between the Mirror Modifier and the Subsurface Modifier…

after that… you should be good to go…
