@thecabbagedetective Great questions!
1. Textures are OK to be from places such as Poliigon, TextureHaven or Game Textures. The more you create however, the more bragging rights you have to all of your cookie friends. 😎
2. That sounds rad, and it’s Blender. A big thumbs up! 👍’
3. Once the contest starts (tonight at midnight or just before I turn in for the night). I will launch it, and there will be a “Submit Entry” button on the contest page. This is where your entry must be submitted to be considered. You’re welcome to share your entry here, it’s own thread, instagram or gallery to show off the work in progress, or keep it a secret and drop the mic at the end of the contest.
Hope this helps, and look forward to what you create!
