Render Pass

Beginners
1

Hi folks,

something I have been trying to wrap my head around. What’s the point and use of a render pass?

What’s the difference between render pass and a straight render?

Thank you!

A render pass will re-use the render buffer memory allocated in a Render TOP. It’s faster and has a lower memory footprint than using multiple Render TOPs.

Great. Thank you.

Hi, I was wondering if there’s still advantage in using Render Pass TOP over Render TOP if both depth and color buffers are cleared on the Render Pass?

Was wondering the same as dancing_pixels!
When creating a camera rig with equal resolution renders but different camera angles, is it more efficient to use render passes?

Hi @jonaswolter,

Have a look at the wiki article on Multi Camera Rendering:

Ideally you would specify all cameras in a single Render TOP and use Render Select TOPs to retrieve the additional camera render outputs.

Hope this helps
Cheers
