The default scene set up, at least in 2.8+ is meters, right?
First, I noticed most tutorials I’ve scene for things like physics don’t change anything…but then they model things Not to scale. This bugs the heck out of me because that can cause Lots of issues. First, your simulation looks cool, but if you want it to look real, then it’s wrong.
Unit scale is one that interests me because the manual explicitly says “This only influences the values displayed in the user interface and not how things behave internally. For example, physics simulations don’t take the unit scale into account.”
But when I did a small simulation in mm that failed miserably, I changed the unit scale and it failed miserably Differently. But wouldn’t that suggest that it shouldn’t have effected it at all?
So I’m curious what the proper way to set up scenes would be for different units, and scales. I live in the US, so I have to use inches Often, but realistically I’m working in mm. I switch to inches just to enter a bunch of inch information, but generally I’ll switch back to mm, cm, or meters, depending on the scale I’m working with. House? Meters. Car, cm, computer chair-keyring, mm. things the size of computer chair could go either way, but the small details like screws, mm is convenient to me.
An explanation of how to actually set things up for different units and scene sizes, especially when related to physical things like simulations, phyiscal lights and materials, etc.
And it Does make a difference, is there an add-on or something that helps you out switching back and forth? Sure, I could just save scenes with the settings applied in each and just start there. But sometimes you need to switch after the fact.
