What Scale ?

[anon_59597335]

Hi I am a new one in Unity. I have read some tutorials, but I’ve got no explained the specifics of the optimum scale of objects to be used in the game (Unity). I really appreciate for any explanation.

Thanks

I dont think it matters? aslong as its all in proportion then i dont see why it would matter? (maby performance or something prehaps maby someone can shed some light on this)

Good luck with unity it truely is a wonderfull program, wish you the best

The scale matters only when dealing with the physics engine, which works best when 1 editor unit equals 1 metric unit. In that sense, Unity is a metric program.

The scale doesn’t matter as far as I’m aware. Although I’d recommend working in a scale of 1, for easy working with imported models etc.

EDIT: PeterB has given the correct information it seems.

@PeterB would you be able to direct me to any information about the scale and the physics? Or explain in a bit of detail yourself?

The physics section in the manual talks about the importance of scale:

Use the right size

The size of the your GameObject’s mesh is much more important than the mass of the Rigidbody. If you find that your Rigidbody is not behaving exactly how you expect - it moves slowly, floats, or doesn’t collide correctly - consider adjusting the scale of your mesh asset. Unity’s default unit scale is 1 unit = 1 meter, so the scale of your imported mesh is maintained, and applied to physics calculations. For example, a crumbling skyscraper is going to fall apart very differently than a tower made of toy blocks, so objects of different sizes should be modeled to accurate scale.

If you are modeling a human make sure he is around 2 meters tall in Unity. To check if your object has the right size compare it to the default cube. You can create a cube using GameObject->Create Other->Cube. The cube’s height will be exactly 1 meter, so your human should be twice as tall.

Yeah, scale has a big impact on how a game’s physics work. I remember setting up this control system, and I had to take all these ridiculous, unnecessary steps to make it look right.

Turns out, my character was 50% bigger than he was supposed to be. Yeah, not even a full 100%, and it made a huge difference.
