Physics Iteration & Voxel Generator Version

I have yet to find info about this understandable to non programmers. Can anyone here explain in layman terms what Physics Iteration and Voxel Generator Version means? What does the different values in the sandbox.sbc mean?
I noticed when creating a world that the PhysicsIteration value seems to be 4 as default (?) I read somewhere it has impact on how realistic the physics are handled but dunno what the different values actually mean in practice, e.g the difference between 1 and 4.

Same with Voxel Generator Version. On some of the worlds I've made I've noticed the value has been automatically set to 1 and sometimes 2. What is the difference? Trying to "optimize" the settings when creating a procedural infinite world for MP-DS.

 

Voxel generator version affects type and group of voxels that are generated
Version 2 was introduced when ice was added, so if you have world with oxygen, you need to have Voxel 2 version.
Most likely planets will require Voxel 3, since there will be new content (grass, dirt and stuff)

Physics iteration mainly affects colision computation, but also object motion, more itteration, more passes when testing for colision (well there are also other things affected, but this one is most important), and smoother motion. While it's good for better dynamics, it's also more demanding on your computer (or server). 4 is midway value. If you server cpu can't keep up with computation, you can set it down to 2 or 1, if you have good cpu and want more precise physics, people even set it to 10, but that's really taxing on cpu, and also on memory.

 

Thanks a lot for the explanation. Very helpful



I just realized that the voxel generator version on my current world is set to 1 but I do have ice and oxygen.
If I set this to 2 instead, will it have any impact on an already created world?

 

i think, i've seen somewhere on forums better explanation of voxel generator settings. i will try to find it and will add link later.

So I guess both 1 and 2 have functional Ice.

I must have missed it earlier.
