SketchyPhysics 3.5.6 (26 January 2015)

Before I try it on my Win8, I would like you to clarify. So you pressed play, paused at desired time, saved as, reset simulation, close the model without saving it again, opening the saved model, and you have your rocks at current locations.
If you did save after the 'save as' then here is your problem... Saving after the 'save as' will overwrite the 'saved as' model.

Except the case of the "save as" that is not yet resolved for me for mysterious reason
how works the "explode volume" ?
It's just scripting or there is a Menu / Button for apply this function to a selection of Groups / Components ?Its just scripting. Would of been helpful if I could understand which part you are confused on.
Here are the steps I would like you to follow, on how to save broken rocks. Please reply on those that don't work or you're confused on.- Open a model and select a group you want to be broken.
- Open the SP UI, and paste this code in the scripted field:
onStart { split(self, 2) }This piece of code will split body when simulation starts. Change 2 to higher value if want to split body into more pieces. Make sure the scripted checkbox is checked. - Press physics toggle play button to start simulation. You will see that your body got split into pieces.
- At desired frame, press physics toggle play once again to pause simulation. You may either press it right away after simulation starts to maintain full form or when pieces of rocks fall and rest on floor - Its up to you.
- Once simulation is paused, go to (Menu) > File > Save As and give it a different name (don't overwrite the default model).
- Now you may press physics reset, and close the current model without saving it.
- Open the new saved model, and there you will see cut rocks at desired locations.
- Now, before you use them it is essential to erase all hidden temporary pieces of rocks. So, enable view hidden geometry option, and delete all hidden pieces of rocks.
- From there, you may use the left over rocks for your purpose.
The sketchyphysics split method was meant for ingame effects, not for saving purpose. A plugin could be developed that will split body into multiple pieces though. It's very simple and I will create it for you.

Bingo all works with the 3.53 !!!
Great! Just a side note: Viewing the picture, I see that all pieces have box collisions. Set their collision to Convexhull2 for proper collisions generation.

Bingo! All works fine with the 3.53 !!!
The problem is resolved and was in the N° of version of SketchyPhysics (for me) !
You rocks!
-
Thx for the Hint of the Convex Hull2!
-
I'm glad it's resolved

Your plugin "Split" is excellent!
It's a part of the "physic" engine or your own cooking?

Just copied code snippets from SketchyPhysics and some cooking of course

Okay, I've fixed enough bugs. Moving to MSPhysics now!
By improving SP, I learned quite a lot, especially the ideals and approaches to take when writing MSPhysics.
It's now up to Chris Phillips and other interested in such plugin to enhance and add features. I will no longer keep supporting SketchyPhysics as I am quite busy with College and need to make some progress in MSPhysics. Other than that, I won't mind answering questions on how to properly use SP.

Hi Anton,
Sorry I haven't been more involved during your flurry of input - you've done really well. When I get time away from current work I've got some cool projects to build which you have enabled.
Thanks again for your input.
Also, just checked out MSPhysics - great stuff - if I can help test or something then please keep me in the loop.

Thanks ashscott, and no need to be sorry.
Some descent features were supposed to be added to make SP3.5 as attractive as the plugin's first release, but I was too lazy too do that -

A typical example...
Thats very strange. When I added option readback collision geometry to the vehicle, there were 3 collision shapes below it, which came out from nowhere. That's some strange effect with default shape. Meantime for the fix, set vehicle shape to convexhull2 or compound2 for proper collision generation. Convexhull2 is preferred as it's the fastest.
I can't reproduce this in SP3.2, so that's some bug by me, which must be eliminated. I will look into fixing it.
Thanks for report.
-
If You add option readback collision geometry to the wheels You will sea that it happens only with flipped objects/groups ...
-
Okay, it is fixed now! Please download latest version and see how it goes. Thanks for report, faust07
-
It works. Thanks again Anton. The door to the "Physics World" in SketchUp is wide open ...
-
-
I think I see what you did there
-
Oh no, Anton I don't want to nerve you. I cheered too soon. A model that ran in SPh3.5.3, jolts in SPh3.5.4 a little ... Probably the steering blocks are squeezed out laterally from the body of the truck. I hope the GIF example shows what a little.

Si ça peut être utile !?
Thanks for your documentation, patrick. I placed this in first post, as part of reference.
