I made a little list with how many constrains there are in some of the more "common" free rigs out there. I made the list just to compare with my own latest rig(with 92 constrains), but maybe itīs interesting for you guys too.
Here is the list:
JJ (from the AFR tutorials): 32
LowMan (the grey one): 109
LowMax(the brown one): 215
IK Joe: 276
Of course speed in a rig depends on alot of other diffent things:
* Number of expressions
* Geometry resolution
* Segmented geo or smooth bound geo
* Deformers for the geometry
* etc, the list goes on and on ...
In my experience, the JJ-rig by Jason Schleifer is the KING of speed. Itīs wicked fast! On my slow computer, the frame-rate almost never goes below 40fps! Itīs a pretty complicated rig and he still get that speed ... impressive. The pros know how to do it I guess :)
Finally, I donīt want anyone to take the list as critique to your rig. If you donīt want to be on the list, let me know. I just think itīs interesting.
The script I used for finding out.
//list all constrains in the scene, and print out the names and number
//It asumes that the constrain-nodes are not renamed, but thatīs not something anyone does as far as I know
select -r ("*Constraint1");
string $sel = `ls -sl`;
print ("Name: " + $sel[$x] + ", nr: " + $x + "\n");
