Hello,
I am trying to scale the player down/up relative to the world around him/her in VR. For example, I would have a standard cube and when I hit a button or set a parameter, the player becomes tiny or giant compared to the standard box.
Thanks for any help you can provide. 
Check out the “World to Meters” scale. By default, I think it’s set to 100.
Can you elaborate on how this works?
If I place my character in the world and a cube (standard size) and adjust the world to meters scale, will my character scale grow/shrink compared to the standard box?
Thanks
Yes, this is how it works, you can set it at runtime e.g. like this:
In this example you will be a giant, but be aware that this will scale everything in the world…
Cheers
