Can someone help me please I repost

It depends on what details you want to display

And what kind of interaction you plan to implement

There is no universal answer, think about how you will use it and then scale it to make that easy

I just want to make the Solar System rotation

You want to model it, like for a school presentation ?

I have a more precise question that can help me understand I think. What is the measuring element of Unity, what is for example 20 when I put it in X of Position

[sullen bridge]

No just to learn, I don't care if it's only a sphere

It's just so I can learn Vectors, rotation, and parenting

[sullen bridge]

Because if I have the unit I can just convert it and scale it down

You won't like the answer ahah => In theory 1 unity unit, is one meter, but you can choose to do otherwise based on the meshes you have, or for you solar system : the constraint to represent it

[sullen bridge]

That help me a bit I guess!

Can I ask you how you will do the scaling if you were doing the Solar System, so I can have an example ?

What numbers would you choose ?

[jovial badge]

I'd just throw a camera in a scene, two sphere roughly scale like the sun and the earth and then choose from that (I mean the ratio needs to be correct)

I assume you want to pan and zoom into your solar system at some point, so thinking in terms of camera angle is a good way, imo

[raw sluice]

yep, it's about 1 meter per unit but you can use it for any scale you want bc you can't make the solar system to scale. get the distance between the center point of your solar system and another object, then scale based off that for the rest of the objects . . .

And is there a way to see how much ressource my "game" cost ?

[jovial badge]

Yes

Go the the analysis tab, and there is plenty of debug tool there

[sullen bridge]

If so, I could just convert in meters and scale it down at the perfect point where it cost the less amount of memory

[jovial badge]

To see memory allocation, cpu Usage and so on

[sullen bridge]

Sorry, where is the analysis tab ?

Found it my b

Thanks for all the answers guys!

Just another quick question

If I put a sphere with Scale 1, 1, 1 and another scale with 20, 20, 20. Is there more detail on the 20 or not ?

[jovial badge]

Yes

I mean

If the texture you apply on it, is 20 times larger

And if not, it will be as "detailled" but just scaled up
