First Model Challenge - July

July - it's hot, it's the best time of the summer and a good time to enter the good old competition with your fellow 3D designers!

We're keeping the show going - approaching the mid-summer, CGTrader has teamed-up with SolidRocks to bring in a renewed First Model competition for all the 3D modelers and enthusiasts out there! All you have to do is upload your first 3D model to our platform and there's a chance you'll bring home a SolidRocks license for your 3ds max or Cinema4D.

Put your modeling gloves on and show us what you've got!

Frequently Asked Questions

Please go through these questions before contacting us

Do I need to upload files or only images of my 3D design?

You need to upload files and images of your 3D design in order to participate in the challenge.

I don't want to put my entry model for sale. Do you have any suggestions?

Does earning money from your digital files sounds like a bad idea? Just try to put higher price on it, let's say 300 USD.

I don't want to loose copyrights on my model after it is sold.

There are General, Editorial and Custom licenses for you to choose under which you want to operate. Individuals or companies which bought your model can't use it for commercial purposes if it hasn't been changed. So no worries - you won't lose the copyright.

How can I participate in the challenge?

Design awesome 3D model for 'First Model Challenge' and upload it to CGTrader. Your first uploaded model is automatically considered an entry to the competition.

What if I put the required tag on my already published 3D model on CGTrader - do you treat it as a valid entry?

No. Only 3D models uploaded in the period from the 1st of July 2016 to the 1st of August 2016 will be treated as valid entries.

Do free 3D models participate in the challenge?

Yes, absolutely. Sharing artwork is always appreciated in the community.

Can I enter with 3D models which participated in other challenges elsewhere?

Yes. There are no restrictions on publishing and selling your models elsewhere.

Do price tags play any importance when entries are being judged?

No. But do not forget that the prices are always judged by the customers.

I want to participate in the challenge so I am going to delete my already uploaded models and upload them again to meet the "publishing period" requirement. Can I do that?

No. We are tracking every deleted and uploaded model, so it is useless to drive-through our requirements of the challenge.
