I asked this a while ago, and Scrubs doesn't want to have the library contaminated by non-official decals (which I find sensible, when I think about it). But you can still use your custom decals for your renders using Blender or any other 3d application.

It is a lot of work to handle official decorations. If I add custom ones in the same way, it would be carnage 😛 If it ever happens on day, it will have to be thought of very carefully.

I fully understand that MecaBricks library should not be contaminated with non-official decorations.

On the other way, does anyone have an workflow or explanation on how to use Blender to render your MOCs done with MecaBricks, with custom decorations?
I'm a completely noob with Blender and didn't find a tutorial here. Sorry if I overlooked something and missed it.

Hello,
This is not too complicated once you understand the workflow.

• First, you need to draw you decorations as if they would go into Mecabricks, following the same rules https://www.mecabricks.com/en/forum/topic/630
• Then when you build your model in Mecabricks, use placeholders where your custom decorated parts will be. By placeholders, I mean the same element with a decoration that you will replace in Blender later.
• Once the model is imported in Blender with one of my addons, you will have to do manually what the program does automatically. To simplify this:
  

Many thanks Scrubs!
I'll definitely give it a try, soon!!

Wonder how to do it for elements where a decoration does not yet exist in Mecabricks, or when you want a contiguous decoration across multiple parts... but let's address one problem at a time! 😄

Custom decorations should be a thing, just if someone goes to the workshop, they can only see their own, in a folder not in the library.
