Hi

All rigid body actor objects (falling objects duplicated with alt + d or sift + d) are gone after pressing esc in p (simulation bake) mode.
In baking i can see all objects after that only 1st orig objects, other orig (exact clone) objects are gone.

What ?

hemm…

maybe some screenshots could help us understand your problem.

I made a screencast video but camstudio made again broken file, it does it when file goes over 4 GB in Vista ntfs file system.

So i write it down

  • I have object - i made it to rigid body so i t falls down with gravity and interacts with other objects
  • Then i duplicate that object
  • Then i hit P to bake
  • Then i hit esc
  • Then ony 1 object is left and other is gone

I had 40 objects + instanced 5 x 40 copies
after bake i have only 40

Now i did duplicate 1st and then made it to rigid body, took me 2 hour (long time for camstudio 4 gb limit, even with 5 fps 720p divx cbr quant 1, file size was 2,3 GB = broken file)

But i have another problem.
I had materials assigned for 40 objects and links to luxrender materials and rigid body setings, soo i wasnt able to duplicate unchangeable bad data,
so i appended another 40 objects with links to materials in blender and luxrender but now the last have bad material names like xxx.001 and if i change it to xxx then 1st object material renames to xxx.001 and so on. But it must be the same material and no materials in drop down list.

How can i get frame 3000 as clean mesh data with 240 objects together correct materials, so i can export it and append i f i need. Maybe there is a way to export frame nr-. 3000 geometry and materials to new file. And 160 objects are instanced, can i keep instancing. I wanna loose the physics data if possible.

Thanks :yes:

I got it nice and clean, exported to obj then imported and joined by material. :slight_smile:

If you have done any animation in the scene and left the “Automatic keyframe” button ticked, this can produce the problem because every time you duplicate it, blender creates an ipo for the new object at the duplicated position. Hitting p will send all duplicates back to their original position.

Thanks

Did a little search and found out that where automatic keyframe is (top menu), was also an interesting button.

Problem solved :slight_smile: :wink:
