Render only the elements - without beaty pass?

[maxpardo]

Is this possible? I started an animation and realized that the check box was unmarked so I rendered 100 frames without elements.

Can I render those 100 frames elements without rendering the beaty pass?

I would really appreciate any help since the rendering time is big in my scene and can't wait for those frames to be rendered

thank you so much!

Hello,

For what i know, you can't.

But, if the elements you want are not related with the lighthing. Like UV pass, ambiant occlusion, ObjID, MatID... you can render your scene without any lights, it will no take a lot of time.

What I did once is set beauty pass and everything else, but since I only needed the passes for object ID and alpha mask I set the max samples to 128 and rendered it out normally, I just deleted the beauty pass files afterwards.

This probably won't work with other types of passes (but for the reflection pass or shadow pass for example it's not like you'll get it out any faster even if you could render it out on it's own, it still needs to get to the number of samples you would pretty much require for a clean beauty pass)

But yes, if you just need the alpha mask or object id elements, you can definitely do it the way I described above. Just set overall sample rate to 128 and render out everything. Masks and object IDs don't need anything more than that.

Just make sure you change output folder so you don't overwrite your original beauty and other passes with the low quality ones.

Thank you so much for your help!

I need The ID passes so it could work for them

You can also keep your samples high and just change your Kernel to info channel and selected a quick-pass from there, like Mat-ID. Then all the other passes will render too that you need, and the 'beauty pass' is really just the Mat-ID you selected.

Oh thank you DartFrog for your tip

I'll give it a try
