Scan based materials on a budget /  by Xuan Prada

Hello patrons,

Last post of the year!

In this two and half hours video I will show you my workflow to create smart materials based on photogrammetry. A technique wideky used in VFX and the game industry.

But we won't be using special hardware or very expensive photographic equipment, we are going to be using only a cheap digital camera or even a smartphone.

In this video you will learn:

- How to shoot photogrammetry for material creation.
- How to process photogrammetry in Reality Capture.
- How to bake textures maps from high resolution geometry in Zbrush.
- How to create smart materials in Substance Designer for Substance Painter or for 3D applications.
- How to use photogrammetry based materials in real time engines.

Thanks for your support and see you in 2022!
Stay safe.

Xuan.

Happy New Year!

Real time rendering for vfx episode 04 is here!
This is a long one, around 4 hours split in two different videos, both of them available already for you.

In these two videos I cover a lot of things related with lighting and rendering in Unreal. We will cover all the rendering methods, rasterization, raytracing, hybrid rendering and path tracing.

Some of the topics covered in this video are:

- Rendering methods in Unreal.
- Lightmass.
- Type of lights.
- Volumetric lighting.
- Modulate lighting.
- Global illumination.
- Mesh lights.
- Reflection methods.
- Post processing volumes.
- Particles lighting.
- Blueprints for lighting.
- Light function.
- Core components of a lighting scene.
- Neutral lighting conditions.
- Rasterization.
- Raytracing.
- Hybrid methdos.

Real time rendering for vfx, episode 02 /  by Xuan Prada

Hello Patrons,

It's been a while since I posted a video here. I did a little bit of traveling (not for fun though) and I've been super busy at work, but I finally managed to put something together for you guys.

Episode 2 of "real-time rendering for VFX". This episode is boring, really boring but also very much needed. If you really want to get into real-time rendering you need to go through everything that I explain in this video. I will cover very important topics that you need to know before starting to create any content for real-time.

Concepts like occlusion, overshading stages, lightmapping, vertex shading, distance culling, rasterization, and many other fancy terms that you necessarily need to understand. This video is almost 5 hours long so I hope you don't fall asleep and learn a few things to put in practice soon.

As usual, please let me know if you have any questions, concerns, suggestions, feedback, etc. And also, thank you very much again for your support.

Right now we are 199 patrons, let's get up to 200 and do something to celebrate it.

These are some of the topics covered in this (almost) 4 hours video.

- Assets considerations for real time.
- Exporting/importing assets in Maya/Unreal.
- Using templates in Unreal.
- Collisions.
- Materials basics.
- Lighting/atmospherics basics.
- Exporting projects.
- VR scouting.
