FREE TRAINING: The Multi-Pass System

[inlifethrill]

Hey guys, I took some time to prepare a quick introdution to the newly introduced Multi-Pass system in OctaneRender for Cinemea 4D.

Part 1: Beauty Passes / http://inlifethrill.com/trainings/octan ... ty-passes/
Part 2: Lighting Passes / http://inlifethrill.com/trainings/octan ... ng-passes/
Part 3: Render Layer / http://inlifethrill.com/trainings/octan ... der-layer/
Part 4: Layer Mask / http://inlifethrill.com/trainings/octan ... ayer-mask/

Hope you find some good info in it. Ahmet helped a lot, big thumbs up! Like & share.

Best,
Dobs

Hi Dobs,

Congratulations on the video tutorials! They explain render passes very well and I would also recommend them to users not using the C4D plugin just to get an overview of the possibilities of render passes in Octane. I really like the fact that you show how to actually use those passes in Photoshop and the emphasis on linear workflow.

A few minor points of critique/clarifications:

• In part 3, you enable the shadow pass to capture both the black shadows and colored shadows but there aren't any colored shadows. The colored shadow pass is white. There aren't that much colored shadows to see so I assume you forgot the Fake shadows option in the specular material or the Alpha shadows option in the kernel.
• To clarify, the layer masks weren't developed as an improvement because you can only render a single layer at a time as mentioned in part 4. And they certainly don't work with depth-of-field and motion blur. We developed the render layers because we wanted something better than masks. Masking introduces edge artifacts (a.k.a. compositing halos) as explained here. You can see it in your video from 7:51 to 7:56. When you change the look of the floor, you also see the edge of the pink sphere in the background changing because the mask isn't perfect. Same goes when changing the blue sphere. This is a fundamental problem with masking that can't be solved. So I would classify using masks as the old school way of doing things.

The pink sphere's edge is changing when the floor is changed. This is a fundamental problem with masking.

Keep up the awesome work!

cheers,
Thomas

Moved the topic into the general tutorials forum since the concepts apply to Octane in general.

Thanks a lot for the work!

Thanks for the notes Thomas!

Just to clarify - I did not forget to enable fake shadows - I just never meant to use them. Me going for "shadows" instead of "black shadows' (which was probably the right way to go..) was due to the fact I like working with data captured in the rgb channel rather than in the alpha. A bad habbit on my side probably.

Appologies for misleading the audience - Layer Mask cannot capture dof or motion blur. It was an incorrect statement.
Thanks for bringing that up!

Aprreciate it abstrax!

Best,
Dobs

Dobs, these are awesome mate! Thanks so much for explaining an area that was keeping me mystified.
