Hello, I am currently working on my server and this includes designing new furnitures for example a table. I already picked a lot of blocks which can be used to remodel, but my problem is, that I do not know which blocks are generated by the world generator and which are not. For an example, I can't use any logs because, well, trees have logs and it would be pretty ridiculous to see tables stacking up and then leaves coming out of it from the top . I need a full list that provides me information regarding this matter. Which blocks are not used by the world generator and are only available from crafting? Please help me out.
