Ancient Robot Challenge

2nd CG Boost Art Challenge for 3D Artists with Prizes worth ~$3,920!

Artwork by Sergey Grechanyuk


Welcome to the second CG Boost Challenge with the topic “Ancient Robot”!

This art challenge is for all 3d artists wanting to improve their skills and get the chance to win prizes worth ~$3,920!

This is our second challenge at CG Boost, however, we have quite some years of experience in running digital art challenges. 2015, we initiated the SculptJanuary event, which is still running today and shortly after that, we established the Weekly CG Challenge, which eventually became the CG Boost challenge after 143 challenges!

This challenge is for 3D artists only. The main goal is to improve your skills and create a 3d render for your portfolio. Besides that, you have the chance to increase your online exposure and win great prizes worth ~$3,920 provided by some of the best companies in the 3d industry.

In the spirit of growing together, you can join our Facebook community of aspiring artists, ask for or give feedback to help each other improve.

Before you get started, don’t forget to read the rules.

The challenge ends on Wednesday April 24th, 2019 at 23:59 CET!

Good luck everyone!
~Zach and the CG Boost team

Update: KIT OPS joined as sponsor for the CG Boost Challenge! They are providing one license of KIT OPS PRO as prize, an advanced kitbashing add-on for Bender. Learn more!

The topic for this challenge is “Ancient Robots”.

Traditionally, robots, androids and similar machines belong to the genre of Science Fiction. But what if the age of robotics already started several hundred years earlier, in our past? What would robots from ancient Greece or the Middle Ages look like? Or maybe imagine a daring adventurer discovering the remains of gigantic robots from a forgotten civilization! Is all there is left just a bunch of rusty crap? Or is there still life inside the mechanical brain, just waiting to be reactivated?

Please make sure to read and follow these rules carefully, to ensure that your final entry is eligible for the judging process.

  • Your entry must relate to the challenge’s theme (we encourage you to be very creative with that)
  • Your entry must be a 3d rendered image (no animations or Sketchfab models)
  • You can use any 3d tools, renderers, add-ons and techniques of your choice
  • You can use any visual render style of your choise (like photorealism, NPR, low poly etc.)
  • You can submit only one work
  • Your entry must be a new and original creation specifically made for the challenge (no existing projects)
  • Your entry must be create by only one person (no group)
  • 2d or concept art is not allowed (but can be used to plan your final 3d scene)
  • No fanart allowed
  • Paintover and Photobashing is not allowed
  • Minimal post processing is allowed (like color adjustments, adding elements like smoke, fire, particles etc.)

No. You can only submit one (1) submission per challenge.

No. Your entry must be an original creation created by you. We can’t accept copyrighted or patented content for legal reasons.

Photobashing and paintovers are not allowed. However, you are allowed to enhance your image with color and brightness adjustments or adding effects like smoke, fire, particles etc.

Can I use third party assets?
Yes, but in a way to support your scene. The external assets can’t be the main focus of your scene.

Can I update my submission during the challenge if I notice a mistake?
Yes, just re-submit your work, and we will replace it. Please add a quick note on what you have changed. The only condition – you cannot change the idea of the work, or modify it drastically. Only reasonable changes are allowed.
