Rendering concepts help

Hey Unity3D Community
I’m coming from a different environment such as Maya, Max and I was wondering if there is any possebility in Unity3D to render your scene with an image output such as .exr or .png or any other kind of image so that I can put it into a compositing program. My idea is to create a short movie with an output that I can take it in other applications and do the final twick.
Thank you for your help

Render to a texture and write the texture to a file. Here’s an example:

you can use some third party plugin for that in asset store.
what you want probably is just screen recording, but if you actually want passes you will need some advanced solution or do it yourself, by taking them using command buffers.
