Well, there's always the stuff in my modding blog, if that counts as a guide :p
"You are not permitted to derive profit from your publications."

Releasing a mod, alongside a monetised YouTube video to showcase it, would be a derivative profit from making the mod.
I'm sure you would allow for such a thing, as I'm sure what you mean is we can't make people pay for mods for your property.
I know this might be nit-picking, but in legal matters I personally don't like to leave things up to interpretation.

Updated with the latest guides and resources, also changed the layout a bit and the wording of Besiege's modding permissions to include an answer to TGYD's question about video monetization.
Hi everyone. Sometimes then i playing besiege i want to make my own blocks. So, i can create model in 3dsMax, also i can work with unity3d. But i don't know besiege's game architecture. I need some examples how to create game-like blocks in Unity and export block file for Blockloader. In this topic i see only scripting guide, but i know what people make blocks mods too.

Von, there is a problem with the tgyd's blockloader link, when I try to enter the link, it says that an error has occured. What should I do if I need that page?
The blockloader is implemented in the modloader now

Sorry for the bump but the forums links don't work because of the migration to XenForo
Links are still outdated :(
Most of the info is pretty outdated by now (this is from 2015 march 25th), so it's better just to check the modloader thread. That said, the modloader hasn't been updated to the latest version yet.

And if you want more info on how to create mods, it's better to join the discord and ask there
