Physics Simulation

[daeyeoplee]

my intention is to drop the objects and then render their final physical simulated frame
just one frame

I found

bproc.object.simulate_physics_and_fix_final_poses(4,20,1)

but this code gets Error: Cannot apply to a multi user: Object "FT001", Mesh "FT.001", aborting

so I wonder two things

1. that function said this will run the simulation and fix the final resting pose of each object and simulation itself will be discarded.
   Is that mean that If i use bproc.render() i can just render objects' final position frame?

2. How can i handle that Error?

3. or If i misunderstood the function, how can i handle my problem. I want to render about 70th frame only, and I don't wanna waste my resource to render 0~70 frames. set_frame didn't work..
   Ps. in the link there's what error happend

thank you

Hey,

but this code gets Error: Cannot apply to a multi user: Object "FT001", Mesh "FT.001", aborting

I have not seen any usage of a multi-user object. Could you maybe share a minimal example of where this error occurs, so that we can replicate it?

Is that mean that If i use bproc.render() i can just render objects' final position frame?

Exactly, only the last position is saved the rest is discarded.

How can i handle that Error?

Please provide a minimal example with code and blend/obj files.

or If i misunderstood the function, how can i handle my problem. I want to render about 70th frame only, and I don't wanna waste my resource to render 0~70 frames. set_frame didn't work..

Usually, if you use the function you only have the 0 frame. The whole simulation runs for 70 frames, but all of them get discarded and the final position is saved to frame 0.

maybe i can make my repository of my project and share my code.
But i'm new to open source and not an expert in license problem.
So is it okay to share my blender.py file in github repo? I used your open source library.
Should i set the license same as our GPLv3? or Should I mention the source?

Thank you for your help.
I really appreciate it.

You can just zip everything and upload it here by drag and drop.

You don't need to set a license.

base.zip

I used this code.
Thank you.

I wanna drop my chocolate bars and render it for instance segmentation
