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.

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.

Katana Fastrack episode 02 by Xuan Prada

Katana Fastrack episode 02 is now available for all my patrons. I cover how to create a proper look-dev template to be used in visual effects. Everything will be setup from scratch and at the end of this lesson we will have a Katana script ready to be used. In lesson 03 we'll be using this script to do all the look-dev for Ant-Man.

In Katana Fastrack episode 02 you will learn:

- How to create master look files
- How to use live groups to create light rigs
- How to create a look-dev template for production

New Tutorial Release – Creating HDRI Environments for 3D Lighting by Xuan Prada

My new course for Digital Tutors in out.

What you will learn

In this series of tutorials we will learn how to create HDRI environments for 3D lighting and use them in Maya and V-Ray to light a 3D asset.Throughout the training we will cover the whole lighting process and creating a complete shot from scratch. We will start shooting HDRI on set and we will finish the final shot in NUKE, integrating a 3D asset in a real environment.


By the end of this tutorial you will be able to shot your own HDRI panoramas and create 3D light rigs to light your own projects.

Texturing for VFX film projects. Case study by Xuan Prada

These are the key points of an introduction lecture which I gave about texturing for VFX film projects.
We used different assets on the class but this is the only one which is not copyrighted and I can show here.
I created this asset specifically for this course.


- Check the model.
- Render a checker scene.
- Decide about the quality needed for the textures. Is it a hero asset?
- UV mapping.
- Organization methods.
- How many UDIM’s?
- Photo Shoot.
- What kind of lighting do I need?
- Accessories. (Color checkers, tripod, polarized filters, angular base, etc).
- Bakes. (dirt maps, dust maps, UVs, etc).
- Grading reference images. Create presets.
- Clean reference images for projections.
- Create cameras and guides in Maya/Softimage for projections.
- Adapt graded and cleaned reference images for projection guides.
- Project in 3D software or Mari. (Mari should be faster).
- Work on the projections inside Mari. (We can use Photoshop, Mari or both of them. Even Nuke).
- Create  a 16 bits sRGB colour textures.
- Test colour channel in the light rig.
- Create a 16 bits gray scale specular textures.
- Create a 16 bits gray scale bump textures.
- Create a 16 bits gray scale displacement textures.
- Create a 8 bits gray scale ISO textures.
- Look-Dev blocking.
- Import the light rig.
- Create a basic pass.
- Checker render (matte).
- Checker render (reflective).
- Create clusters.
- Block materials.
- Look-Dev primary.
- Set up diffuse.
- Set up specular and reflections.
- Balance materials.
- Look-Dev secondary.
- Set up bump.
- Set up displacement.
- Rebalance materials.
- Set up ISO’s.
- Look-Dev refinement.
- Rebalance materials if needed.
- Create material libraries.
- Render turntables.
