I am surprised that we don’t have as much Minecraft library/community in the 3D Warehouse and the forum for SketchUp.
As I got a bit into Minecraft with my kids, it was really interesting what I was able to put together to set the scene in SketchUp.
I got most of the things from 3D Warehouse. But had to create some new ones along with modifying textures as some of them were not the most up-to-date textures.
About two days ago I remembered that I wanted to learn how to create models for Minecraft, and now that you brought it up, I searched and found out how.
Thanks!
