Each week has a theme which you can see in the graphic below and each day has a prompt which is meant to inspire the artwork that you submit.
You can learn about rules and prizes HERE [www.sidefx.com].
Here are the prompts:

Hi, I was wondering if it was possible to render our scene inside a GameEngine like Unity/Unreal?

Hello, is it allowed to render with the free redshift plugin?
So there are watermarks in the video.

So is the deadline each day midnight EST or EDT? Since its gonna change mid March and I don't live there I'm kinda confused.
In the initial rules said EDT, but in the Day 1 Bounce forum initial post says it's EST... so..
Is is fair to say that if it's time stamped before 12:00 am of next day on the forum post I'm safe?

Would it be possible to open the forum threads for the next couple of days ahead of time so that those of us that actually need to go offline for a day or two will still be bale to their submission in on time?

Is there a resolution restriction for animation?
