Octane 101 Tutorial: Setting Up Multi-Pass and Object Buffers

Preparing my final output settings was a bit confusing when I was learning Octane so I thought I would share a "Getting Started" tutorial in case you're new to the program. This will go over some tips/tricks and gotchas to look out for when setting up object buffers and multi-passes. Hope it helps!

Hey there! Buffer one includes the whole scene by default. In your case, it includes everything(pyramid and BG), except other figures, as they have different buffer ID. Also, if you use buffer for 1 object only, it's much easier to export mat ID or object ID(change by changing «Bake ID» parameter) pass and use those in post. Good luck, Dmytro

[@jeffreyhalalay3281]

Excellent, and to the point info. Exactly what I was looking for, thanks!

[@trscheit]

You've probably figured it out by now but if you have an object tag on your floor by default it's Layer ID is 1. So when you render you're seeing your floor and triangle on the same layer and it looks like it's not working.

[@trscheit]

Another thing you can do is to make an Octane object tag. Set its Layer ID to 100 or something similar. In the attributes panel go to Edit > Set as Default. Now whenever you make a new object tag the layer ID is set to 100.

Thanks for the tuts! Can we actually render passes without rendering the beauty?

[@siddiqshaheentap]

sir can i render passes with PNG? why nessessory PSD?

[@annaszakir5837]

im not getting the multi passes in my assigned folder but they are showing into my picture viewer section of layer its happening with me often but some times it works fine im using octane in c4d R19

[@alicel7342]

Me too. Do you resolve the issues?? If so, would you let me know the solution for issue?

[@Voolcan]

Quick and straight to the point. Thank you.

[@benjamineshagpoor9854]

Great tip! I've been using Octane about as long as you have an it took me some trial and error to figure out he multi-pass render.

[@k2incho]

Thanks a lot man!

[@yuezhang5551]

thanks! it is an awesome tutor

[@johnsahhar9415]

I've watched multiple videos, a lot of people have been having issues with layer 1, best to just skip it like you said

[@gibito3873]

ID=1 is a default value for every object in the scene - Documentation. So it rendered all white with the piramide included, but other IDs excluded.

[@alicel7342]

Hi,Guys . I need you helps!!!! But I couldn't get Multipass file in the assigned folder. Do anyone know to figure out the issues?

[@VaryprshotOfficial]

Hi, hopefully i get a reply, I was wondering, does the MAIN RENDER gets done in the multi-pass or do you still have to set up the file where to save the main render and passes desperately ? Hope that makes sense. But thanks for this video, really made things clear.

smart

[@123TickTickBoom]

Windows is the worst OS ever! I´ve been trying to render and import masks to AE without any success... FUCK MONKEYSOFT!

[@aspirante.a.vagabundo]

Thanks!

[@zedzara4122]

hey, thanks for your video! do you know how i can render out my object's position/scale/rotation in keyframes through octane? I know the standard routine would be to put an external compositing tag on to the object, but with that my null will be dependent by the camera layer (in AE), and it will block all my render passes.

[@adamross2208]

That's insane that the object buffer passes add so much render time using Octane. Looks like an rgb multi matte pass using the standard render is the way to go if you need object buffers.

[@gfxlbimedia]

very helpful and yes happens the same with ID1, but now I know that I'll use other than 1... thank very much...

[@Nielsc4dtutorials]

Great vid. Thanks!

[@super9tv]

Thanks man! Really helpful.

[@RonaldvallejoA]

Hey am no export am learning as well, but many ids 1 it giving problems because every element is by default assign to layer 1; great video, dude!

[@drewnix7201]

Layer ID 1 is a special layer reserved internally for Octane. Copy and pasted from OToy support

[@yapp7172]

is there anyway to object buffer a specific polygon selection on 1 model?

[@hyebinbin]

Thankyou!!

[@daveycrockettla]

How do you render the main pass? I was able to render the Demain Pass and the Z Depth pass but i cant figure out how to render the main pass. Thank you to anyone who sees this and knows the answer

[@daveycrockettla]

is It Render Settings>Save>RegularImage>File?

[@jordybuijsman7385]

Octane uses a Object layer ID of 1 by default for every object in your scene(with or without octane object tag applied) And because 1 is default you won't see it in the render passes. Can't remeber which video, but he explained it better than I can.

[@johndemsay230]

Great tips thank you very much !!!

[@JustFranzeh]

are you using the Octane VR subscription based plugin for this?

[@thepixellab2011]

Yes I am. It's a pretty rad deal!

[@ChrisCDXX]

Just what I needed. No explaining what a buffer is for noobs. just how to do it in octane. Thank you sir!!!!

[@1mann1wort1]

You are my guy Thanks for your energy in doing so much good for the comunity *****

[@thepixellab2011]

Oh thanks dude, appreciate that!

[@pencewd]

Have you exported a DOF/Z-depth?

[@thepixellab2011]

No, I haven't done that yet...

[@titouanharel2985]

thanxx
