2019.3 Invisible physics scene predictions

Unity Engine
1

hello,

i am building a game and i would like to have ultra accurate collision prediction in my game… I am using untiy 2019.3b8 and i would like to take advantage of its new updates… specifically the physics scenes one may create. even the invisible one… there is one example i would like to share which is in the untiy blog at this adress… it is the example with the billiard balls and the prediction system they are using…

i believe they are using an invisible physics scene. but as it is new, i would like to ask if anyone know how they were able to create this example…

  1. how to create an invisible physics scene

  2. how they were able to create the predicitons…
    etc.

any help would be appreciated…

You need to use separate physics scenes. Here’s a simple working example on how to do that:

i saw this and ran it, but it seems the physics scenes that are created are visible, how can i make this invisible…

i have a setup of objects. i would in theory like to have the invisible physics scene literaly in the same position of the default scene, but invisible…

ive been looking for tutorials and scripts to help understand this method, all i could find is the script you sent and a video on you tube but the guy is kinda non coherent…

so there isnt much information on this yet, if there is a section in the docs i could read i would like to… but cant find it… making invisible and such things i need

Just remove or disable the MeshRenderer components in the second physics scene, right after copying them. This will prevent the copies to be renderer to the screen.
