Textures & shaders

It's been quite a while since I wrote my last post and this time I'd like to show off my new experimentations with shaders for personal work and several textures I did for the awesome guys at Gametextures.com. This was a great opportunity to improve my workflow and experiment with several styles.

During my time of workflow improvement and texture skills improvement I have sculpted a few Insert Multi Mesh assets. For example this set of rocks.

 

Besides that I have worked on a new personal project but it's pretty much in the concept phase so that I'll have to keep for the next time. ;)

Please feel free to check out my breakdown/tutorial for creating this rain shader in UDK.

This shader is still Work in Progress, but the gif shows a clear idea of the shader in several states of wetness on the surface. But the main thing that got me stuck with this shader is the blending/animating of one wetness state into the other one, I want to create one state of wetness "flowing" into the next state of wetness. This is rather challenging for me mainly because of the fact that I'm not a programmer or shader artist by trade, so figuring this out is pretty crazy.

First Character (first) texture pass

Quick post to keep you guys updated on my first character! It's a quick texture setup in marmoset, adjustments have to wait a lil' bit until I have more time on hands :(

You have to enlarge the image in a new window to see it at full resolution.

Please, do drop a comment with feedback though!

Post Apoca Update

Work in Progress - Another update on the Post Apocalyptic environment I'm working on. I've re-adjusted the roof and the broken concrete pieces on the floor. Besides that, I also tried to adjust the composition a bit so the viewers eye would be led through the composition. Also the shaders/textures have been modified/optimized, the lightmaps have been optimized and I enhanced the light setup.

After making the level run smoothly, I started adding collision and LOD's. Personally it felt really interesting to make a big level from start to finish and optimizing it. With that in mind, I do have a few extra props I need to finish. E.g. a car, extra vegetation, 2 extra buildings, water puddles with realtime reflections and perhaps a bus. It doesn't look like a lot of work but when you break down these things into seperate workloads it's going to take a lot of time.

Recently I had the question if I was going to make this a flythrough or a set of screengrabs. To be honest, I don't feel like doing a flythrough since I have been spending a lot of time on this project already. I do like the idea but I might have to do a shit load of extra buildings to make it look like a dense city.

What I Did This Winter - Art Dump

Hey readers,

It's been almost a month since my last post, for me, 2013 didn't start off quite as well as I would've hoped! My computer had to be repaired in the second week of the year already. Thankfully the repair didn't take that long and I was able to upgrade my computer. Windows 7 is now starting within 30 seconds and Photoshop and Max are opened within 5 seconds and run smoothly with all the heavy (extra) plugins. I'm really amazed how much faster SSD's work, at first I was skeptic but I've completely changed my mind.

Besides that, my Dad (who is 71 as of writing this) has joined a computer club! He barely worked on a computer before but now he really wants to explore what these machines are capable of. I just wanted to point out I'm very proud of him that he had the guts to start working with computer at his age.

Tileable textures

The tileable textures are created in Zbrush, where I started with the high poly mesh and applied the polypaint during or after the texture composing.

Destructible Study

I was working on these destructible studies to explore how concrete reacts in different circumstances. All are sculpted in Zbrush. As you can see the top row are all concrete studies and the bottom-left one. The last few sculpts are old/rotten wood.

Organic - Hand Study

I picked this asset up after one and a half year. Back then I think I got overwhelmed with all the anatomical terms and the complex forms. As some character artists even refer to hands as being one of the most difficult shapes of the human body.

Somehow I've decided to finish off some of my older project that I left unfinished. I learned a lot of tips and tricks concerning art creation, so I've decided to put the knowledge I've gained to the test. I really enjoyed the texturing/polypaint process, it felt so easy/logical to add in small details in the texture on top of the high poly mesh. This tech is something I'd like to use more often if possible.

Low Poly - The low poly is realtime viewed in UDK with the new DX11 features like Tessellation and Subsurface Scattering  The asset was intended to be develop for a next-gen game consoles, I also kept in mind the edge-flow for animation. So if you're interested feel free to animate it!

Shader - It's a rather simple setup with the added DX11 features in UDK. Most textures are 2048*2048px except for the sub-dermal texture, for example. The tattoos, to optimize texture load I've made a multichannel texture, so in one of the green-channels I copied in the tattoos. I've also added another UV-channel, where I mapped the part of the model I'd like to show up the tattoos. The con of this method is - an extra texture (eventhough it's multichannel in this case), the pro - I can have a set of hands with or without tattoos and I have a rather high pixel-density.

Organic - Tree Branches

All modeled from High Poly meshes, baked on Low Poly planes. Was very fun to experiment with the new workflow. Texturing is done more quickly and the meshes look more detailed, compared to the trees that I've done in the past.

2D Study

As in the previous blog post I've stated I'd like expand my 2D texture skills, especially I'd like to make environments and weapons.

Lighting Artist pt.2

Hey all,

Welcome back on the blog and I'd like to continue with my "special" on the job function called Lighting Artist. Last time I showed some color simplifications to visualize more of the color tones that are being used to set a certain mood in game environments. I haven't learned anything concerning color usage and composition during my study, but as I am writing these blog posts I am learning to understand these topics better. It's not a professionally written post but more or less the findings I discovered and my interpretation of artists' their work. If I'm wrong with any statements I make during these posts, please leave a comment!

Intro

Before I go any further with the lighting artist special, I just wanted to tell what I've been up to lately. This weekend I've been polishing my online portfolio. Mainly adding some extra screenshots for projects and adding some description. Also optimizing jpg's is a big thing! The smaller the images the quicker the site loads, I kept this in mind but of course you don't want your high poly mesh showing up as pixel art.

Another thing that has been on my mind, one of the biggest game stores in the Netherlands shutdown all of their physical stores and is only going to sell games through their web shop. I'm somewhat disappointed this is happening. I can't imagine any more game stores disappearing because of the economic crisis.

One last thing, I wanted to wish all the people at Trion Worlds who got laid off last week, the best of luck. I think it's a bit of a nasty move to lay off 40 staff members just 2 weeks before Christmas, unfortunately lay offs are a common trend in the games industry.

Lighting Artists pt. 2

The following examples show off how crucial color contrasts and silhouettes are to make a believable and good looking scene. With the example that I showed off last time, concerning Tomas Lidström his work, I took the liberty of showing the differences between the edited and original version. The color contrast is very noticeable at this point but also the importance of silhouettes are becoming more clear.

Halo 4

I'm a very big fan of the artwork in Halo 4, although I haven't played it myself (yet). The environments are highly detailed and has an incredibly awesomeness of varying atmospheres. Most of you have already read the article on the Environment Art on Halo 4 but here is the link anyways.

I used several screenshots of the game and took the first example a bit further. By adding some orange lines I'm pointing out one rule of composition. It's referred to by some as "edge flow" or "lines". This means the eyes are being drawn towards the point of interest because of all the edges that lead the viewers eyes to this PI (point of interest).

In the screenshot with the hallway, all the piping and  paneling is hinting the viewer towards the door at the end of the hall. Maybe it's even luring the player/viewer to let him explore what's behind that door.


With the organic/outside screenshot I added orange lines to landscape, I'm pointing out the necessity of having enough positive and negative space usage and the interest of shapes. For example the rocks have a very interesting and organic look and feel. From a distance it's already noticeable that the objects are rocks, that's why we're using silhouettes. Having shapes of objects be as clear a possible to the viewers eyes, e.g. the rough figure of rocks are very easily recognized -> makes the scene more believable.

You're probably asking, why the grey scaled images? Colors can be very distracting at times, by making them grey-scaled, I made it visually more understanding for myself. It helps to see where all the shadows and light sources come from, another important aspect is the sense of depth. Objects from far away become desaturated/blueish tinted.

The contrast becomes lower the further you look away from the "camera", the grey scales are your visual evidence it works. Of course this rule is mainly applied for outside environment/landscapes.

This blog post turned from just Lighting Artist also towards a few rules for compositions haha. I'm gonna end it here, I'm out of writing material even though I haven't discussed everything yet, but feel free to leave your thoughts down below.

One last line, "Happy Christmas and a happy New Year!".

Have a good day!

In the desert

Hey there,

Soooo, I'm back again with another blogpost that I'm writing during lunch time. It's not so much of an impressive post like last time though, concerning my personal work. I did try to make a matte painting, it's still very work in progress.
And I took the liberty of starting on a new small environment that is taking place in the desert. The shader is pretty basic but it was fun to try out several setups and creating a basic atmosphere. I do need to make a paintover so I can figure out a good focal point that will pull the interest in the scene. Ah well, as an artist you always have a shortage of time, unfortunately. Please leave some crits if you have the time to do so!

For this post I was looking for a different type of artist, not an environment artist nor weapon artist, no this time I looked for a function in gaming that isn't very popular. Lighting artist! As far as I know, there aren't that many of these guys in the games industry.

Lighting artist job

The main task for an lighting artist is, of course, lighting up the environment, duh! Kidding aside, besides that post processing is also one of their tasks,this means keeping the color key of the environment in mind, LOD'ing, optimizing assets, (re-)UVing secondary UV-sets and creating paintovers to try out different atmospheric ideas. For some it might sound pretty easy but I do think it's a pretty challenging job, it's not just dumping in a few dynamic lights and calling it a day. A good lighting artist knows how to flesh out his environment with lighting and keeping the environment readable for the eyes.

Like I said, this time I'll show some work of lighting artist Tomas Lidström. He has quite the list of gametitles on his name already! Especially Gears of War Judgement and Bulletstorm are the titles that I admire. Although Bulletstorm wasn't a bestselling game, I do love the environments and unique atmosphere in the game.

Tomas's portfolio: http://portfolio.tomaslidstrom.com/

By the way, I'd like to thank all the artists out there who gave me the permission to use their work for this purpose!

I'd recommend to open the images in a new window to see the full resolution.  

Small color study, I extracted some colors to have a better understanding how lighting artists use their colors wisely to create a certain atmosphere in their environment. Lighting is very important to steer the viewers eye around in an environment/screenshot/painting. In the high contrast images the viewers eye is constantly drawn towards the lightest/most intense light source. Proper lighting setup isn't the only thing that makes an environment complete, the silhouettes are making the shapes of the environment way more interesting.
