thanks so much for your comment! physics simulations are cool within Blender...and getting better with new releases. I'm working on another Rube Goldberg machine now...incorporating more of the capabilities in Blender. Glad this video helped...looking forward to seeing what you come up with!

thank you for the comment and tip...I agree and will keep it in mind when doing this type of modelling in the future

thanks so much!

thanks so much! I am hoping to put together another one...relying completely on the simulation capabilities again...in the near future

hi...thanks! make sure you apply scale to all physics objects (including rigid). without doing this there is a change could move before contact. Another option is to leverage the 'Start Deactivated' option under Rigid Body -> Deactivation - you can elect to Start Deactivated. This will hold them steady until something engages them. Also - make sure your objects are not too close to one another or something else - which could make the simulation jump right away.

This helped. Thanks a lot@@enterprise4701

thank you! For the camera control, this is the only part of the video that was keyframed. I am putting together a 2nd video of a Rube Goldberg machine using more features in Blender and will cover the camera perspective approach...but basically I placed the camera to capture the beginning of a sub-sequence of the video, keyframed it...then moved the camera to another part/end of a video sequence (complete with rotation and translation of the camera) - and keyframed it at the respective ending frame...letting Blender interpolate in between. I repeated this until I had all of the frames covered - then let the keyframes drive beginning and end of the camera shots while interpolating in between.

@@enterprise4701 Ok, I am looking forward to your new video, and hope you can talk about the camera usage by then

hi...I had not heard about the pwnishr challenge and just checked it out...thanks for sharing that! Have you submitted entries to it in the past?

sure…what is your best way to connect?

If you are referring to the frames within the physics simulation, make sure you set (1) in "Output Properties" set the Dimensions Frame "End" value to the desired end frame and (2) in "Scene Properties" set the Rigid Body World/Cache Simulation "End" frame to the same desired end frame. This will tell Blender to run and cache the physics simulation across the entire range - and not just the default of 250 frames

@@enterprise4701 Thank you so much that helped alot!

cool...glad it helped!

axel is a mesh cylinder, paddle is a mesh cube that was reshaped...then both turned into rigid body objects in Physics Properties (passive for axel, active for paddle). Then you need to add an Empty for the hinge...and look at the Objects section on the bottom right at 3:16 to see how to associate the hinge with the axel and paddle...once that is configured, you'll start to get the desired hinge movement!

@@enterprise4701 thanks

thanks for watching! other than the camera movement, the rest of what you see is governed by the physics engine in Blender
