Katana Fastrack episode 05 by Xuan Prada

Episode 05 of Katana Fastrack is already published. In this episode we are going to take a look at the lighting pipeline that we could find in any visual effects studio.
First, I will explain quickly what is the most common workflow when starting a vfx production, from the lighting point of view.

Then, I will explain the recipe that we are going to cook in Katana for lighting shots. And finally, we will jump into Katana to build our lighting template, a tool that we are going to be able to use on many shots and sequences in the future.

Before finishing this episode, we will try our lighting template with very simple assets, testing features like importing look files, shading override, shading edits, geometry edits, etc.

Clarisse scatterers, part 01 by Xuan Prada

Hello patrons,

I just posted the first part of Clarisse scatterers, in this video I'll walk you through some of the point clouds and scatterers available in Clarisse. We will do three production exercises, very simple but hopefully you will understand the workflow to use these tools to create more complicated shots.

In the first exercise we'll be using the point array to create a simple but effective crowd of soldiers. Then we will use the point cloud particle system to generate the effect that you can see in the video attached to this post. A very common effect these days.
And finally we will use the point uv sampler to generate huge environments like forests or cities.

We will continue with more exercises in the second and last part of these scatterers series in Clarisse.

Thanks,
Xuan.

Katana Fastrack episode 04 by Xuan Prada

Katana Fastrack episode 04 is already available.
In this episode, we will finish the Ant-Man lookDev by tweaking all the shaders and texture maps created in Mari.

Then we will do a very quick slapcomp in Katana and Nuke to check that everything works as expected and looks good. We will do this by render a full motion range of Ant-Man walk cycle. And finally, we will write a Katana look file to be used by the lighters in their shots.

Nuke IBL templates by Xuan Prada

Hello,

I just finished recording about 3 hours of content going through a couple of my Nuke IBL templates. The first one is all about cleaning up and artifacts removal. You know, how to get rid of chunky tripods, removing people from set and what not. I will explain to you a couple of ways of dealing with these issues, both in 2D and in 3D using the powerful Nuke's 3D system.

In the second template, I will guide you through the neutralization process, that includes both linearization and white balance. Some people knows this process as technical grading. A very important step that usually lighting supervisors or sequence supervisor deal with before starting to light any VFX shot.

Footage, scripts and other material will be available to you if you are supporting one of the tiers with downloadable material.

Thanks again for your support! and if you like my Patreon feed, please help me to spread the word, I would love to get at least 50 patrons, we are not that far away!

Katana Fastrack episode 03 by Xuan Prada

Episode 03 of my Katana series is out. We are going to be talking about expressions, macros and tools to take our look-dev template to the next level. Right after that, we will take a look at the texture channels that I painted in Mari for this character and then we will start the look-dev of Ant-Man.

We divide the look-dev in different stages, the first on is blocking, and we are going to spend quite a few time working on this today.

Introduction to Redshift for VFX, episode 01 by Xuan Prada

I'm starting a new training series for my Patreon feed, it's called "Intro to Redshift" for visual effects. I'm kind of learning Redshift and trying to figure out how to use it within my visual effects workflow, and I'll be sharing this trip with you. In this very first episode, I'll be talking about probably the most important topics around Redshift and the base for everything that will come later global illumination and sampling.

I will go deep about these two topics, sharing with you the basic theory behind global illumination and sampling, and I will also share with you a couple of "cheat sheets" to deal with noise and gi easily in Redshift while rendering your shots.

Check the first video out on my Patreon feed.

Cheers,
Xuan.
