I remember there was an example on the wiki with some circular floor piece and hand painted brick texture on it showing how its done but I couldn't find it now.
An example is this overhang roof. If you deleted those edge loops from the middle, the model would still look the same but be using less geometry. The fundamental thing to keep in mind is that your model is really nothing but vertices. And a vertex is three numbers (0,0,0) that define a point in 3d space. So, the fewer…
The connection is indeed weird, but thats because it has weird topology so you can't lay the uvs out nicely. I pointed this out earlier. If you take a look at any of the examples we posted, its clearly possible to align those lines nicely, you just need edges to align to. Why would you put em in Painter though? That…
Just lead the edges in a way that they form an arch. So you can spit that part in the uvmap and align it horizontally to a tiling brick texture. Basically, add an extra edge loop at the spit. The cylinderical parts of the castle could be slit up like 1/8 1/4 1/16 etc. You can make a curved wall with a window hole and one…
