How Do I Rig a 4 Piston V-Engine

I have rigged a 4 piston engine following revolt_randy’s tutorial Rigging a crank and piston in blender 3D

Find enclosed 4 Piston rigging by me. I am having a problem rigging a 4 Piston V_Engine also enclosed.

Anybody help

Do you really think your request for help in rigging is better posted in the ‘Blender & CG Discussion’ forum rather than the ‘Support / Animation and Rigging’ forum ?

Please take 2 seconds the think before posting, it’s not rocket science !!

You will need to layout 4 X crank to piston setup for each cylinder. Since Randy use Crank Rotation bone to rotate his rig, each crank needs to be parented to Crank Rotation bone.

Randy is controlling piston slide with pistonLoc bone as a guide with Limit Location constraint. The setting works for upright cylinder / piston configuration. If you rotate the assembly to make V where cylinder is no longer up right, the setting will need be adjusted so that you use Local Space.
