Hello All...
Well one of the items I have great interest in is the new physics simulation in TS 7.5 player.
In the past I have had a few scenes that took to long to simulate and still had issues (objects 'sticking' together no matter the settings on the Simulation).
With that I have attached a TS 6.6 scene.
Could someone load this into TS 7.5 and run the simulation starting at frame 30..and maybe post an avi file of the results as well as time to simulate frames 30 -90?
If you select the large sign you can then (in TS 6.6) select 'per object simulation' and add a small amount of adhesion (in TS 6.6). I am guessing things are similar in TS 7.5.
Well hope to see some results that are superior to what I have already done on TS 6.6. Example would be the 'cans' on the sign get 'stuck' to my collision box or one another (The box is just a simple object to stand in for a final spaceship model). As well as other objects not responding to collisions. Or colliding and sticking together.
The new chain link physics sample video for TS 7.0 got me thinking that the new simulator may be more up to the challenge.
Thank you in advance

I ran my sim with a Constant Time setting of 4 on simulation quality

(no textures on sample scenethough the 'wood' texture appears to floating around somewhere)

Just for kicks here is another short video showing similar 'issues'. Though this was run with a ConStant Time of 1 on the Simulation Quality.

2.25 MEG...no sound...640 x 480
8-9 seconds
Camera zoom 'issue' missed before render...oh well |

Hmmm...
On loading the scene I just a big hierarchy of all the objects grouped together and no physical attributes assigned to anything, so running a physical simulation does nothing. Can you check the scene and make sure it is set up ready for a simulation to run?
By the way, some of the geometry looks a little crude to expect a reasonable simulation accuracy (those large surfaces on the main sign for example) and using a constant time of 4 would also yield low quality simulation results - unchecking constant time would be better. |

Sorry I assumed that to get it all into TS 7.5 would make my settings in TS 6.6 useless....? Here is a revised scene with the simulation setup for TS 6.6.

Note I am only interested in how the new simulation engine handles the simulation

Sure..I am aware..but it does become a resource/time issue at some point, and I have had similar problems with more complex geometry.
Also I am assuming that since the new simulation engine is touted as being 'factors of magnitude' more accurate than the previous engine that even with low settings / geometry I should expect far better if not faster results.
PS..not looking for a lesson on running a simulation, though much appreciated, just want to compare just how much the new engine improves this particular scene's simulation.
Seeing as we have no Demo of TS 7.5 yet this is my only way.
Thanks again Bobbins for the quick reply |

The deep hierarchy in your scene is proving hard to get into Workspace. I can get the geometry over but not with the physical attributes. I've tried splitting your hierarchy out by decomposing it into objects but still can't get it across the Bridge with the physical properties intact.
The scene really needs setting up on the Workspace side to test but I don;t have the time at the moment. I might have a look at the weekend if I get chance, unless somebody else wants a go? |

A+ for effort Bobbins, as I was hoping it would be 'easy' to setup in the new simulation but had no real idea what to expect. |

I did see a section of advice (chapter near the end) in the 7.5 manual about hierarchies being a drag in the new version and how to speed things up. If the grandmothers/eggs rule applies sorry! (browsing on physics interest)
