Render Textures and Cinemachine Brains

stonstad · Jan 20, 2022

What is the mechanism for associating a specific cinemachine brain with a virtual camera?

- I use the first cinemachine virtual camera and brain for controling the player's camera.
- The second virtual camera and brain controls a camera which renders to a render texture.

The second camera is for a viewscreen in a cockpit when players talk to each other. Having a cinemachine virtual camera for the second camera is terrific because of the realism it provides.

The problem I'm seeing is that when the second brain is active the first brain is disabled. When the first brain is disabled the player's view is invalid. It appears that an easing transition occurs when a change occurs.

How does one work around this limitation?

Thank you!

The setup here is really simple: you create two Unity Cameras and attach a Cinemachine Brain to each. You can then create as many Virtual Cameras as you need.
To make sure a Brain only sees some of these VCams, you just need to do three things:
Make sure the VCams you want to affect a specific Camera are on a unique layer (for instance, “Characters”).
Set that Camera’s Culling Mask to render that layer.
Set the other Camera’s Culling Mask to exclude that layer.
Keep in mind that even if the process is using the Culling Mask of the Camera, this doesn’t mean you need to change your rendering. With 31 Layers to play with, you can just create one specifically to put VCams on.
The full process is also recapped in the video at the end of this article
