#3d environments

What was looking at us smack in the face next? Oh right, we agreed that we were going to make this a 3D game.  The only thing I had done in 3D since college was make a new little penguin for the Wii U title Percy’s Predicament. If any of you happened to see the original Percy with its nightmare eyes, you’re welcome.That  was using Maya no less, which for a little indie operation was a luxury we weren’t going to be able to afford. Matt and I then took it upon ourselves to check out Blender3D to see if it was a viable option. It was open source, so we really hoped it would be. 

My background in the game industry thus far had been as a concept artist and art director. My work with landscapes often is what got me the job and I was typically expected to do mostly environment work. Background painting was something I was used to, so I assumed that environments were going to be my responsibility. I naively thought that I was going to be the one to be the environment and character artist- an all around 3D modeler and what not. I am very very happy that is not what ended up happening. 

Matt wanted to take a shot at environments and cut his teeth on this liquid world. We started with some very straight forward modeling in Blender using mostly primitives, working up to sculpting tools, and then looking at our ugly gray creations. I was inordinately proud of a stupid podium I had modeled that could stack with one another or stand on its own as a center piece. I remember how sad I was to not have it incorporated in the game at the time. I was stupid. This is a lesson to all you developers, no artists in...you know what everyone that makes something. Throw away your work. Fail fast. Don’t get too attached too quickly. Believe me, you will make something afterward and it will probably be better. 

Something else they don’t tell you when it comes to an operation like this- concept art became a bit of a luxury. All of my concept work was messy, plain, and primarily done on paper. We had to move at break neck speeds if we had to figure out how to make this game and get it on the market in a timely manner without crunching too hard. The guys still tell me we never really had crunch periods and I think back to those 2AM nights in horror. God the AAA industry brutalizes their employees. Anyway, so concept art. Right. I made a few pretty paintings in the beginning and I had to be able to show something before modeling a character so that the right design was made and the team could work together on what looked best. I’ll reserve more of this for later, let’s get back to the environment art. 

After a video chat with Darren and Matt’s previous employers, the Bala brothers, Matt started to really expand his horizons and learn even more new programs to enhance the look of the game. Things progressed very quickly once the game changing (literally) program Substance Painter entered the ring. 

10 Things You Should Do To Create Awesome 3D Environments (Part 2)

Have you ever attempted to create a 3D environment and found that your final render falls a little bit…flat?

Most likely, you may have missed an important step in your scene creation process. Here are 10 things you should focus on if you want to give your 3D environment the best chance of looking awesome and get one step closer to achieving photorealism.

We continue from Part 1 to show you ways to bring out the best of your 3D environments.

Use a physically-based renderer

A physically-based renderer is a renderer which simulates lighting exactly as how it is represented in the real world. It produces results far better than raytraced renderers. Unlike raytraced renderers, a physically-based renderer knows calculates how to bounce light rays from objects to other objects and this can help easily simulate photorealistic lighting.

It would probably be a bit complicated to understand exactly how it works. From an artist’s point of view, a physically-based renderer helps produce photorealistic lighting and textures with very little effort compared to the old raytraced renderer. Your 3D environments will look really awesome

The downside to physically-based renderers are that they are slow. Really slow! This is due to all the complex calculations that need to occur on your scene. When I created my short films, the average render time per frame for a film made using a raytraced renderer (Blender Internal renderer) was 5 minutes. The average render time per frame for another film made using a physically-based renderer (Cycles renderer) was about 1 hour. It’s not much of a big deal if you are only rendering still images, but rendering an animation using these renderers can be quite tedious.

What to do: If you use Blender, there is a physically-based renderer already inbuilt. On the top menu, just change the renderer from Blender Render to Cycles Render.

Use HDRI Lights

Lighting a 3D environment can be complicated. There are so much complexities involved with simulating realistic and convincing lighting and one would need to understand some lighting theory. In the past, 3D artists would create multiple light sources to simulate sunlight, sky lights, bounce lighting and things like that. The result would be a 3D enviroment scene with a big mess of lights everywhere.

Nowadays, the most popular trend is using HDRI lights in combination with a physically-based renderer. HDRI images are high-dynamic range images and contain more information such as brightness and intensity data within the one image. We can make complete use of this to simulate realistic lighting. Physically-based renderers can help remove the big mess of lights as it helps realistically simulate bounce lighting. Combine that with HDRI images and our 3D world can be realistically lit up without the help of really ANY extra lights at all. You could get away with using the HDRI to control the lighting for your entire environment.

Make use of HDRI images as a light source in your 3D scene to help push for more awesome realism and visual appeal!

What to do: Grab a HDRI sky image on any HDRI image download site. I prefer to use HDRI-Skies.com. Load up your HDRI image in your 3D software and set it up so that the intensity information contained within the HDRI could help light up your 3D world. In Blender, you could load the HDRI image directly in the Environment Texture node of the Sky. You would also need to capture the same HDRI image as an input for the strength/intensity. There is no point in having a HDRI image if you don’t make use of the extra information available within HDRIs. Do note that HDRI images are generally quite large and may crash your scene while rendering. That sacrifice may be worth it, however, depending on the result you are able to get from it.

Make use of photography techniques

If you have ever taken classes in photography, your skills have not gone to waste. You can fully utilize those skills in your 3D renderings as well. If you haven’t, then taking some time to learn some of the basics such as composition, f-stops, depth of field and so on will only do you a world of good.

What to do: In Blender, you can select your camera and go to the camera settings in the Properties window. From there, you can play around with some of the settings that you would tend to see on a DSLR camera. You can even simulate the look of a specific camera such as a Kodak camera or a cinematic camera like those powerful RED cameras, by going to the Scene tab and under Color Management, changing the “Look”.

Go subtle with post-processing

Once your render is complete, you should take advantage of post-processing. Post-processing can help to push your renders to the next level and give that sort of “pop” or that extra “wow” factor to your final render.

Some of the post-processing effects you could take advantage of includes adding glare, vignettes, glows, depth-of-field, motion blur, color grading, lens distortion, overlaying images over the original render and the list just goes on.

But remember to not go overboard with this. The bulk of the work should have been done in the modeling, texturing/shading, lighting, and rendering. The post-processing is just a touch up to give that final polish.

You will kill the appeal and realism of your render if you go overboard with the post-processing effects. In the art world, subtlety is always key!

What to do: Use a photo editing software like Photoshop or GIMP. If you use Blender, you can also use the compositor built into Blender. Just change the Screen Layout on the top menu from Default to Compositing and then select ‘Use Nodes’. Each node can be used to create the effect you desire.

Get feedback (and get them early)

The final tip that will really benefit you and help push your 3D environments to the next level is getting feedback! While you work on your 3D environments, show it to other people and see what they think of your work so far. Try to get their opinions early and try to get them often.

When you create your environments, you are so immersed into your world and you will likely focus on one specific area. This may cause you to overlook other areas of your environment and sometimes getting a fresh pair of eyes can be beneficial in this regard. They can help you catch issues with your render that you would have otherwise overlooked.

Getting feedback is really important as it can also help you improve as a 3D artist overall. However, you will need to learn to take criticism with a grain of salt. Sometimes you will get very encouraging feedback and other times the feedback could just be downright vicious. If you want to improve as an artist, you need to observe, understand and learn from the honest criticism. Getting honest criticism is almost always beneficial to you as an artist. Use the encouraging feedback as motivation and the pointless and vicious comments with no real substance as a waste of space (they only do this to get attention or perhaps a little envious of you).

What to do: Be active in communities related to 3D! Try being active on online forum sites like CGTalk, BlenderArtists, and relevant Facebook Groups to name a few. The people there encourage works in progress and are always more than happy to help! That’s it! Incorporate these tips into your next epic 3D environment and you’re 3D renderer will gift you by giving you beautiful renders.
