MULTI PASS RENDERING AND COMPOSITING WITH ROBBY BRANHAM tutorial series 04

 

I'm now on part 4 of this specific rendering series.

It is essential to look at he raw passes of your 3D render as you can experiment with the image more due to it's colours compared to a JPEG which will affect the whole image in one colour. Raw lighting gives more flexibility.

Select:  raw light, diffuse and lighting

What this does is give us the render with different settings. These settings include black and white filter, and glowing colours of the render.

The raw lighting is the ray tracer.

Diffuse is just out colour information.

The lighting is the scene with shadows.

We get ray tracing from raw light, diffuse and lighting.

You would find these all In the render settings master layer render elements tab.

The tutorial already had made presets to use = Render elements- beauty multiplication.

Like Maya, in Nuke you would set the project once exporting these diffuse settings.

To edit the latest Maya branches in nuke, bring in a shuffle mode and a raw lighting pass. Bring In raw lighting pass and branch out of it diffuse.

connect the raw file to the chain previously made with premult and unpremult.

You can divide lighting and diffuse to give access to raw lighting. You would first merge the diffuse and lighting to then divide them. If it appears black and white then hit shift + x.

Take raw lighting and raw GI and multiply to have more access to lighting information.

Multiply diffuse with raw GI and merge together then plus (+).

Combine this data with raw reflection, grab reflection filter and divide together.

Once these are to your liking you can export them into other scenes, so that you don't always have to make them from scratch. These are called comp notes.

Major final animation

This is it, the final animation, the culmination of all these months and blog posts. There was a slight hesitation on "WHEN" to post it leading up to it due to rendering times, but as it's complete and there's no reason to add extra stress and upload it on the last day, which is the 18th of May, I'll upload it now. Reacting to the animation, I'm quite proud of how far I've come from the previz. During the previz stage, I was unaware of Substance Painter and how much it could do for me. I was also unaware of After Effects, as I prioritized Adobe Premiere above it. However, I have found After Effects more user-friendly and powerful, regardless of my prior history with other editing software. As displayed in my blog posts by me, I did have to look at Youtube for help, and I was honest with that to help me improve on unfamiliar equipment.

Major not losing lighting

Image
  This is the original scene when the boy is amazed by the stairs sign in the new flat.  I added lips to my character in this scene, but if you look closely there are highlights on his bottom lip, the original scene did have highlights around the mouth so I did not want to lose that.

PRE-VISUALIZATION FOR FILM WITH JASON MICHAEL HALL continuing shot blocking

 Anything that does not fit in a master file, like lights for instance is better suited for work files. When you want things to disappear in the same scene you can keyframe their visibility, like broken windows, for example.   Pointing is a very bad action in animation. When a character points it shows no: body language, the movement of the camera, the composition of the scene, or cinematography skills. All these should be used to tell the story without pointing. Pointing is a lazy shortcut that means you lack artistic vision. A left-to-right screen direction is great for action as it is how we normally read in the West, and by keeping it consistent it makes the camera less chaotic. The more scenes you block out, te easier it is to see how they compliment each other in the sequence. It just helps with new shots and improving existing ones. Cutting is great also, like angles, inside a place when it's normal, outside what changes it and inside again to show the new state, this m...
