I recently bought the Art Of book for Assassins' Creed: Unity as I began to think about what I wanted to do next for my portfolio piece. I came across a piece of concept art by Félicien Nourry for a building in the game's rendition of Paris that I liked and saw an opportunity to explore a lot of things while keeping the scale down.
Original Artwork by Félicien Nourry
In beginning this project I defined two faults I've had when planning previous projects which I saw had room for improvement; the first being a lack of proper reference gathering as I tended to do the bare minimum in the past and find references as the situation arose. The second being that I would typically gather my reference from games.
While from a learning perspective there is value to using game art as a reference; I would use it to understand the approaches and techniques the original artist would have used, it more often left me recreating what I saw the artist did rather than take my own lead.

[Matching real references to the concept]
Once I had the concept and had done a look over the gathered references I started plotting ideas for what I wanted this project to cover.
I've reached a comfortable point in my learning where everything I've done so far has covered some aspect of environment art creation, and so it's easier to have a greater picture of the project going forward, and now start looking to take my work further.
One aspect of environment art I've come to really enjoy is the shader sets ups and how far you can go with them. With each project I've dabbled more and more with what I can do with shaders typically covering them in blog posts.
With this project, I want to put my experience to practice and create something more advanced that could fill a lot of my needs.
The general idea is to compose the building of modular components utilising weighted normals in combination with tiling texture workflow across all assets to cut down production times and limit the number of unique assets necessary. This means I can focus on implementing an advanced shader using material blending and masks to get an interesting final result that avoids the obvious repetition that comes with modular work, as well as explore using more than UV set per item.

The general idea is to have one UV Set be texel density correct, allowing a tiling texture or trim sheet to be applied through it. The second UV set is a 0-1 pack of the modular components where I can, using stencils and generators in Painter, paint detail for material blending, dirt and more.
I also want to explore experimenting with different texture packs and textures themselves used, something inspired from this presentation by Ben Cloward in his 'Shading the World of Anthem' GDC presentation - https://www.youtube.com/watch?v=IjQWRjWZGn0&list=PLjOKHSnRUhd0QYEgTLJUseNxL_qoI2rcc&index=2&ab_channel=GDC
Some of the videos that have inspired me:
Technical Artist Bootcamp (GDC) - https://www.youtube.com/watch?v=-LHj7-kROoo&ab_channel=GDC
Directed Procedural Workflows - https://www.youtube.com/watch?v=Up97rAuXBwU&list=PLjOKHSnRUhd3fzzBZBAVJXQYfDfppQhHZ&index=5&ab_channel=Houdini
Procedural World Generation with Far Cry 5 - https://www.youtube.com/watch?v=NfizT369g60&ab_channel=Houdini
My eventual goal is to be more comfortable with procedural workflows to speed up my production times in the future and maybe one day dabble in Technical Art roles. So the idea is to lay the foundations to my understanding with this project by implementing Houdini where best. The most immediate plan is to do this with rain generation and wetmaps on the final building that can be used in conjunction with the shader to get a more realistic final look, or even snow buildup.
A recurring element I've seen across a few job postings has been Level of Detail (LODs) and player collision, two things I don't really bear in mind when working on the portfolio as I focus on it looking good other actually being playable. The aim for this project is to have both components properly implemented in my work, and more specifically have player collision be close to that which would have been present in the actual AC: Unity game.

--Shader and Material Blending Research--
It's always helpful to research and see how studios have approached similar situations within their workflows and take aspects to be used in my own. This helped influence my shader set-up and modular breakdown.
