05: Industry professionals - Thought process creating photoreal textures

In this section I will be explaining how industry professionals create photorealistic textures for 3D assets.

I believe this will help me understand more about the process and discover new techniques to use in various software.

Jason Rod is an Environment artist at Dambuster's studio. In his Artstation he has published a short course in which he explains how to texture an old hand drill. He used software such as Substance Painter, Marmoset toolbag and Photoshop.

To begin with he created a low and a high polygon version of the drill and baked the normal maps using Marmoset. 

In Substance Painter, he set up the scene to feel more like Unreal Engine. He changed the Hdri and adjusted other settings like tessellation and tone mapping, as Unreal is where he normally imports his 3d assets and both software render differently.

Key points from his texturing tutorial:

  • Jason first gathered various references from different websites, to get as many angles as possible of the object. 
  • He then searched for more references of either the same or the similar objects with grunges and marks that he could create alphas from.
  • Separated the different materials and searched for more references according to them. In substance painter he created different folders and created smart materials that he later applied to the drill.
  • He constantly asked for feedback.

 

Chu Chun Yang


Chun Chun is a character artist at Blizzard who has participated in many live events sharing her knowledge. Chun mainly uses Mari however she also includes Substance Painter to her workflow. In the tutorial in which she aimed to recreate the chipped paint and rusty look of a real object, she shared many tips and tricks to create photorealistic textures.

Key points from Chun's texturing tutorial:
  • Stay whiting project time requirments
  • Analyse the asset: How close the camera will be will dictate how much detailed it will have to be.
  • What materials it is made of
  • Collect a lot of references
  • Build the materials from the root
  • Find/create decal stencils.

00: Intro

For this project I will be writing about why it is important to do research before starting your own. I will be talking about photorealistic texturing. Photorealistic textures  Description, what is How it started, history.. what methods/techniques they used at first and how it improved matte painting, compositions? what makes an object real What makes an object photorealistic. What tools do i need to achieve this, whether the softwares i use can be used to make photorealistic textures where is photorealism now and where it is going. Photogrametry? Examples of artists replicating a real object Examples of not so experience artist replicating an object Starting my own project* Stablish a workflow  Real life Reference research,  breakdown of the object, albedo, roughness, metalness, normals, heights what softwares i will need or use depending the method or technique Real life measurements of the way the material reacts to light, real life size How real props used to be textu...

03: Achieving photorealism - Different techniques

Image
There are multiple ways to achieve photorealism using different techniques and software. Depending on the artist and their job or even what they need it for they would use a specific way to create more realistic 3D assets.    Photogrammetry  The Evolution of Video Game Graphics (thelogocreative.co.uk) How Is Photogrammetry Used in Video Games? – PhotoModeler Photogrammetry is the process of extracting information from photographs. It starts with taking photographs and inputting them into a software, such as Recap by Autodesk.  Adjusting the settings to obtain either a measuring, 3d objects or a scene. Films such as The Matrix and Fight club have used this technique before, in Fight club, the scene in wich the parking has multiple destructive equipment, was done using 100s of images.  Fight Club (1999) - Computer Animation history-CGI! (jimdofree.com) The studios that worked on Death Stranding used photogrammetry to create a more accurate 3D character version of ...

04: Industry Professionals - Q&A

In Linkedin, I reached out to multiple 3D artist and asked them a few questions about photorealistic 3d assets.  Message Hi ‘Person’s Name’, My name is Miguel Diaz I’m a VFX student at Futureworks University, I’m working on a third-year research project about Photorealistic textured 3D assets e.g., the evolution of how digital technology has replaced traditional methods particularly in the areas of digital asset texturing for animation, games and film and TV. This will also cover historical techniques from the beginning, present and its future. I’ve created an initial set of questions based on my research. I am aware that you are probably quite busy however, I was hopeful that you could answer some of my questions and give me some useful employment advice.  The questions are: 1.What do you think is the main factor that makes a 3D object/environment photoreal? As the lighting, little details, the object itself? 2. How important is the software that you use? 3. Looking at how te...
