The topic for this challenge is “Alchemist”.

Before the dawn of Enlightenment and the era of science, peculiar scholars named alchemists attempted to uncover the inner mechanisms of this world with strange procedures. What might they have found? What horrendous instruments might they have devised? Whether you come up with an eccentric alchemist character, a complex transmutation device or a dank vault where unnamable things happen, we are eager for your most extravagant designs!

Please make sure to read and follow these rules carefully, to ensure that your final entry is eligible for the judging process. Also, check the FAQ section below for further clarification.

  • Your entry must relate to the challenge’s theme (we encourage you to be very creative with that)
  • You can only submit 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)
  • Your entry must be a 3d rendered image (no animations or Sketchfab models)
  • You can use any 3d tools (even Game Engines), renderers, add-ons and techniques of your choice
  • You can use any visual render style of your choise (like photorealism, NPR, low poly etc.)
  • Minimal use of third party assets is allowed, as long as they don’t take up more than ~20% of screen space of your image and are not the main focus of your scene (third party textures and materials are not included in this rule and can be used as much as you like)
  • 2d or concept art is not allowed (but can be used to plan your 3d scene)
  • No fanart allowed
  • Enhancing your rendering in post is allowed – That includes things like color adjustments, compositing render layers/passes and adding effects like smoke, fire, particles etc. Extending your scene with a sky background is allowed too. Other than that, adding photographic elements (like cut out characters or vegetation) or doing paintovers or photobashing is not allowed.
  • Imagery & depictions of hate, racism, sexism or other discriminatory factors will additionally be judged based on their context & visual narrative. If the entry is clearly promoting or idealizing a harmful agenda then it will be disqualified.
  • You must submit you work before the deadline is over (we won’t accept entries after the deadline!)

Before submitting your entry, make sure that it meets all the following deliverables:

  • You have to submit one (1) final render
  • The final work must be submitted as an image
  • Your render should have 1920 pixel on longest edge (landscape format should have 1920 pixels width, portrait format should have 1920 pixels height – any aspect ratio is fine)
  • Image size should not exceed 2 MB and should be in *.jpg format
  • You can add a small watermark if you like (it has to be small, grayscale, slightly transparent and placed in the bottom left or right corner of the image)
  • 3D models laid on wallpapers are not allowed
  • You have to submit a clay render (render without materials and textures) of your scene along with your final submission

We judge the entries according to these three criteria:

  • Visual Appeal
  • Storytelling
  • Technique

It’s not required to meet all three judging criteria in order to win. You can have great visuals and technical skills without a story or great storytelling with lacking visuals. However, the better you meet all criteria, the bigger your chance to win.

Where do I ask questions about the challenge?
Ask them in the comment section below.

Can I submit multiple submissions for a challenge?
No. You can only submit one (1) submission per challenge.

Can I submit an artwork I started before the challenge?
No. Your entry must be a new creation specially made for the challenge.

Can I create fanart or use a concept art of another artist?
No. Your entry must be an original creation created by you. We can’t accept copyrighted or patented content for legal reasons. Designers of fashion, games, movies and other media do protect their brand and people who breach these rules will be disqualified. Homage or recognizable styles fall outside these rules, but do linger in a gray area. Keep this in mind when designing your entry.

Can I use photographic elements, photobashing or paintovers techniques?
No, but 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 and take up more than ~20% screen space of your image. Third party textures and materials are not included in this rule and can be used as much as you like.

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.

Can I share my artwork online before the challenge is over?
Yes, it is your artwork, you can do whatever you want.
