Thanks, got it!

Ok, thanks for the info!

Hi Jedishrfu, I uploaded a couple messages to that application page. Including a link to a google doc with a draft of the blog post but have not heard anything back.

Sounds like a cool Unity project! It's really amazing how easy those types of simulations are with a game engine like Unity. In the old days of game programming it took a lot more work. It's hard to believe it's free to use. Thanks for the invitation to write an insights blog post. I'll take...

Problem solved. It was scaling mass by scaleFactor3 and not scaling the direction vector. Works great at any scale now. Thanks for everyone's help!

I did some Googling and didn't come up with any specific about the Unity solver other than they have one and the recently rewrote the cloth solver. Here's some info on it: https://docs.unity3d.com/Manual/class-PhysicsManager.html There are settings for "default solver iterations" set to 6...

Angular Drag is a setting exposed on the Unity physics engine's Rigidbody component. https://docs.unity3d.com/ScriptReference/Rigidbody-angularDrag.html They also expose mass and drag. I have tried several values for it and it doesn't seem to change the path much. I tried scaling it and not...

Hi and thanks! That got the scaled down results much closer with the x3 ! I'm still missing something that I should be scaling though, as the 0.5 result orbits are still not stable as the 1.0 scale results. There seems to be too much force and they get sucked towards the center and go...

Hi and thanks for your replies. I will study up on circular motion and centripetal force. It's been a while since college physics class. That's a good point about time. I want the orbital periods to be the same. I just need to be able to scale everything so the user can choose the right...

Thanks for the cryptic non-answer. It "should" scale linearly or "should not" scale linearly?

I need to scale my solar system model and it's not working. I'm making an augmented reality app that shows a sample solar system rotating. It works great! (Thanks to this $7 program https://assetstore.unity.com/packages/tools/physics/gravity-and-orbits-solar-system-105300 . The Unity engine...
