Rigid Bodies and Constraints Workflow in Blender

About

This post will outline my overall workflow for creating a simple rigid body w/ constraints system using Blender.


Workflow

My recent experiment/study was the Hinge constraint in Blender 3D.
physics/rigid_body/constraints/types/hinge I studied the documentation and sketched out my understanding of the constraint on paper.


Initial Setup

Using the Tools->Physics panel of the 3D View Editor automatically adds the rigid body objects and constraints to the correct groups.


Groups

In the Outliner Editor, switch the mode to Groups. This enables one to quickly select the desired object for editing its properties. (also the selectability and visibility of RBD objects/constraints becomes easier)

Property Chart Add-on

Another indispensable tool is the Property Chart Add-on for quickly editing properties of selected and active objects in a spreadsheet like manner. (In Blender 2.67, I had actually contributed to the presets functionality for this Add-On)

 In the User Preferences Window, e…

Principled BRDF Shading comes to Blender

I came across this link on Twitter today and it was a good refresher on what is going on in Blender shading circles. Principled BSDF definitely is going to make the process of creating believable appearances easier and more predictable.

Some references follow now.

Some recent experiments using Rigid Bodies in Blender

Getting started with RBD based springboard simulation and animation.

The only thing animated in the video below is the movement of the cylinder. Rest is from the (RBD w/ constraints/Rigging Curve Deform) system.

The following are from the end of last year.
