Free Art Tool Released Thanks to Epic Friday

At Epic, we have a fun monthly tradition known as Epic Friday, which gives employees a break from ongoing tasks and provides a platform for us to work on pet projects. One day each month, we’re encouraged to be creative and productive solely within the context of “making cool stuff” that benefits our games and technology development process.

Epic Games Senior Environment Artist Warren Marshall recently set out to refine his manual drawing skills. While Warren is both highly technical and artistic, he felt the need to revisit the basics and learn more about perspective.

“Gotta grind those fundamentals,” he said. Voicing how making perspective grids by hand can be frustrating, he continued, “The programmer in me wanted to do something cooler. Enter Epic Friday!”

Warren describes the app he developed, Carapace, as “a simple program that lets you place vanishing points around an image placeholder to flesh out the shell of your drawing. Shell, carapace… Get it?”

Carapace enables users to place up to nine vanishing points or as few as one. One-, two and three-point perspective grids are possible along with some extras to accommodate any weird angles in a scene.

Here’s a video of Warren setting up a simple three-point grid:

• Once the grid is in place, click CTRL+C and to place the grid on the clipboard.
• Paste it into Photoshop and use it as a guide!

“Carapace can also determine the perspective of existing images,” said Warren. “Say you have a piece of concept art that you want to paint over or add something to it. If you can’t work out the perspective, you can use this program to load the image and lay down trace lines. With two trace lines on the screen, hitting a hot key will place a vanishing point at the intersection spot. This saves you trying to figure out where to place the vanishing points by clicking and dragging and guessing.”

See it in action again here:

Today, we’re very pleased to share Warren’s clever app with the community.

* Requires .NET 4.0

      Nice! Hope Adobe and the like will license it to include it as a plugin in future versions.

    • Michael Link

      This is going to help my work immensely. I work in comics as well as 3D models. Thanks so much, Warren! =)

    • Alec Chalmers

      Couple of friends asking, does it work on a MAC? Is it possible to do a browser version so it becomes plataform-free?

    • ActionRPG

      Love it Wish it was on Mac, Its so nice when Gamers share the love.

    • jw

      wow, thank you so much for sharing this! love it!!!

    • Andrew

      No Mac version please.

    • angelize

      In the first video you are moving vanishing points 1 and 2 together how is this done? Is it possible to lock any two vanishing points together like that?

      • Rahll

        He’s actually hitting the H key, which aligns the perspective points horizontally to the cursor’s location.

        • angelize

          Thanks. :)

    • Arun

      Can I import an image into your app and then match my Perspective lines accordingly ??? Mac version would be a great help Warren . Thanks a lot for sharing… it is some thing that i wanted for a long time. :)

      • Arun

        Never mind I did check the PC version and it has the image option (Trace) to it. THanks Warren..

    • Kiwi

      Please for Mac! I would pay for it 😉

    • Ki

    • Whitney


    • Eric

      Great tool, Warren. Remember, don’t fold and release steve’s mac port to the masses. He’s counting on you and so am I. Let those mac fags suffer with their inferior drawing skills.

    • Marshal Uhls

      Mac version indeed

    • DPS

      This is a pretty handy tool – thanks for sharing. A cool feature would be the ability to insert ‘helper’ points, for CP and others that you may want to reuse. Also having a giant cross centred on the principle point for setting out purposes would be great.

    • HumanBeeing

      For Mac, just run it in a Windows emulator.

    • Bruno Cerkvenik

      Mac please!!

    • Dion Harris

      Thanks for this!

    • CesarAugusto


    • bruno

    • kitana

      It always crashes when I try to install it. I have this verison of framework.

    • kitana

      Any help or idea why it crashed and I even can’t install it. I really need it. Thanks.

      • kitana

        Well I find the problem – IT DOESN’T WORK ON WINDOWS XP. All of my friends try to install it and it doesn’t. So just to know. NOT FOR XP.

    • Noldy

      THANK YOU!!!!

    • kaykay mudgle
