Hi, I am trying out this thread.
I have downloaded the ARK Dev Kit, and also watched plenty tutorial windows. But nothing would help me better to learn how to develop mods with the ADK, than creating an actual usable real mod with your help. That is why I am here. I need a step-by-step assistance for the first one or two mods, then i should be able to take off from there. 
Mod 1 that I want to develop:
An ultra-flat square that can snap onto foundations, floors/ceilings, or walls. It will have a texture and will appear like a wallpaper or carpet or tiles, etc.
It must not prevent other items to be mounted to foundations, floors/ceilings or walls, and it also should be mountable to those even if other items are already mounted onto the underground. Please give me a step-by-step guide (can be splittet into several postings). Thanks a lot!
Mod 2 that I want to develop:
an ultra-flat “stripe” that can be mounted on foundations, floors/ceilings, or walls, and that illuminates a room. Not one strong light source integrated, but many smaller ones so the illumination takes place along the length of this light stripe. Light color adjustable with the three RGB sliders (as seen with food recipes), and light intensity also adjustable with a slider.
