For Duviri I started out doing research and development on all the natural related thematics while in constant communication with both the Art Director as well as the Environment Art team who were making the objects I needed.
On a 100x200m space I tested out both foliage growth and rock formations on multiple environments, ranging from meadows and gardens to forests and swamps. Once approved they would first get automatically applied using a scatter system so we could cover and test large environments for gameplay, visuals and performance. Later I would go back and adjust most of these placements for optimal story telling and compositional results that best matched my initial tests.

I ended up doing foliage and rock placements as well as dirt roads and hiking trails on all 3 main islands, the Amphitheatre island and the Fractal Pasture in the Undercroft. Last but not least, I set up little story telling elements such as patio-tables, plant-clusters, stable-tools, blacksmithing locations, and lounging areas that we could then spread throughout the world. During the entire development of this set I worked very closely with Level Designers Mitch Gladney and Kol Crosby, Milton Pangourelias from Tech Art, Cem Cermen from Tools Team, Derek Patterson for Lighting and Stephen Fitzsimmons from Environment Art who delivered all the trees and bushes. You all were an absolute delight to deal with, as always.

This quest-line was created to replace our former tutorial level. It was acompanied with a pre-rendered cinematic introduction followed up with further ingame cutscenes. When the tutorial starts, all the early environments were put together entirely by me; both Level art and most of the general Level Design, exluding the tutorial specific parts. Jeremy Andress for original lighting pass, Derek Patterson for later applying the new lighting technology.

It was made using a mix of existing props from the game and new ones for which I created proxies to have something to work with while environment art finalized them. Proxies included large seqoia inspired trees and their roots as separate pieces. Also structural debris for the Orokin ruins and background cards for trees. Several other pieces were reused from the Plains of Eidolon, Cetus, Venus and Grineer Forest.

Several smaller environments towards the end were reused from the Grineer Forest set and enchanced to match both quality and story telling of the questline. This helped save a lot of time considering it was made with a very small team, which we could then use to prioritize the much larger first half of the quest. 

Driftercamp was part of the New War update and included a boss battle and afterwards a safe space to hang out and customize.
This was a whole new environment meant to become the home of the Drifter character. Almost everything was reused from other sets such as Plains of Eidolon, Cetus, Venus, Grineer Forest and New User Experience. Having this not be part of a procedural system gave me more freedom and the oppertunity in creating a larger environment that suited the story we were trying to tell. The main challenge was that this level would be available directly from the menu. This required it to have minimal loading time and therefore keeping it very low on memory use.

The Level Design was done by Andrew Seyko, I highly recommend visiting his page if you'd like to see some early progress images.
Original final lighting was done by Jeremy Andress with Derek Patterson later applying the new lighting technology.

Dagath Dojo was a brief project with a lot of thematic freedom. The room was meant to house a Warframe that at the time wasn't made yet outside of concept and there was no script either. The only requirements were to give it a horror/halloween thematic, stick to the Dojo metrics, needed a place for said Warframe character and as well a stable for horses of any kind.. It was up to me to decide how to explore this and where to go from there.

Being a big fan of medievil architecture and knowing horses would have some sort of role I chose to go with an crusader-inspired chapel. For the basic architecture I took most inspiration from existing chapels, churches and tombs from that era. Furthermore I took to movies such as Kingdom of Heaven, Interview with a Vampire, Sleepy Hollow as well as the classic monster movies from the 30's. Most of those may not have had a medieval thematic, but were a great inspiration for theatric and dramatic atmosphere. To build the basic structure I reused pieces from the old Grineer Settlement. The additional pieces that added detail and patterns on the floor are Orokin and so are the pieces I used for the chandeliers, which were originally used in entirely different ways and sizes.. The only new additions are the tomb itself, the banners, masks and the stable accessoiries. Final lighting was done by Jeremy Andress, whom I worked closely with in getting the desired outcome.

This set was part of the Call of Tempestarii Railjack update we released. An area that was mostly there to allow people to explore the derelict towers in the area which at times could be linked to quest-lines surrounding the dedicated Railjack experience. As the set is fairly small and contained, most of the Level Art, lighting and effects placement were all entirely done by me. While I used some existing Orokin rooms as a start-off point, applying an infested pass on them often resulted in an entirely different level. This is because I wanted to make it a unique experience to see the architecture in this state. There are as well some levels, such as shown in the first and third image above, that were created entirely from scratch by me.

I was on the forefront of Grineer Forest as well as leading the charge on the Remastered version of this set a couple years later with Sebastian Spatzek as Level Designer.
We started with creating proxy pieces such as trees and rocks and a cave kit. This was followed by creating beautiful corner prototypes that matched the art direction and set a visual example and guideline for the rest of the team. The level in the first image had its Level Design created by Ben Edney. The other two were my own creation, with navigational and gameplay pass from the Level Design department.

The remastered version included all new materials, sounds and lighting. From a Level Art standpoint I went through each and every level to look for improvements and consistency between all the individual levels. Think material usage on buildings, railings and cover, but also redoing entire sections if they could be done cleaner or had space for visual improvement and upgrades to better match the desired outcome.

There were also some technical advances made in between the original set and the remastered version such as the foliage system. This allowed me to not only learn and then apply this to the level, but as well teach my peers how to use them. This technology would later be improved upon further and applied to the Plains of Eidolon.

For Orb Vallis I worked directly with Kol Crosby as the Level Designer and was co-responsible for Level Art in all the Caves with Mitch Gladney. Outside of the caves I also did two large craters that can be found on the surface.
To quickly and efficiently build Level Art for all these caves with just the two of us, I designed a cave-kit that could comfortably follow all the Level Design needs without too much kit-bashing. This could then be dressed up with a more detailed pass to get interesting and unique compositions. This kit included pieces such as straight, corner, 3-way, fourway, entrance and cap which could all comfortably be used upright, upside down, facing each other in a mirrored way and combined with terrain to give us the most versatile results. This kit would later be reused for New User Experience among other areas. The glowing coolant and mushrooms, often the highlights of our caves, were prototyped by myself and finalized by the talented Arif Pribadi.

Before and after comparisons

The images below are acompanied by a screenshot of the mockup showing how I often received the original Level Design.
The level designers focus on the gameplay path and pacing of the level. I will then visualize this to the desired art direction of the set by using set pieces created by the Environment Art team.
