Using simple techniques and free assets I recreated a real castle ruin in Blender and Unreal Engine.

Before you comment: The result is absolutely NOT perfect! From the lack of details on the ground to the low sample count of the final render, there are so many things I could have done better!

Also an important statement: Using seamless textures doesn’t mean, your final render will have less details. This only means that you have to add the details yourself! Especially for beginners, this can be quite hard or simply too much work as you are probably looking for easy techniques and quick results.

Having that said, this tutorial is absolutely not meant for professionals, or anyone who wants to make a portfolio peace to get a job.
