hi all
basically i hav a stretchy bones setup and i want each bone to change color when it has become overstreched so the animator will have some visual feedback. i have watched cg academy intermediate rigging volumes 1 and 2. in volume 2 this idea was demonstrated on a pre made rig but it was not shown how it was done.
any help anyone can give me would be much appreciated
I haven’t watched the DVD’s yet, but I am assuming that you’re using a script to create the stretchy spine, all you need to do is add some more code to that script to make it change colour. As I don’t know what your script looks like I’ll give you some pseudo code:
if (current_bone_length > maximum_length) then -- Over-stretch turn red
current_bone.wirecolor = red
else if (current_bone_length < minimum_length) then -- Over-squash turn yellow
current_bone.wirecolor = yellow
else -- Right size green
current_bone.wirecolor = green
This code will make the colours snap. If you want it to smoothly transition the code get's a bit more complex, but not much.
If you give me your script I can give you the exact code you should use.
As well as Wahooney’s suggestion there is also a free tutorial on http://cg-academy.net thet covers this topic. I wish that I had time to put every thing in the DVD’s
thanks for the help guys and i’ll be sure to check out that tutorial from CGA
