Postwork related question (CLOSED)

Hi! This will be my first time entering a contest here, so I just wanted to clarify something about the post-work rules.

The rule says:
"Post-work in Photoshop or other software is allowed, but the original render must be done in 3D software"

I'm wondering how far that can go. Is it mainly for things like lighting adjustments and color correction/grading, or is adding 2D elements also okay? For example, things like clouds, smoke, god rays, laser bolts, slime, decals and so on.

Basically, at what point would post-work be considered too much and potentially make an entry ineligible to win?

Thanks!

Although post-work is allowed in this contest, it's important to keep in mind that this is a 3D render contest and not a post-work contest. Therefore, focusing on the 3D aspect of the artwork is highly recommended. Additionally, if post-work is used in the final submission, including a raw render without post-work is recommended.
