I have recently completed a model of a maze, however, I am having a hard time texturing it. It's one big object, and I have no idea how to texture it to get a good resolution, can anyone tell me how to texture it with a good resolution.
I see there are a lot of boxes and hard angles in your mesh. As a result, you could try something like this, if you are okay with a certain level of randomness.
Basically, it uses Blender-generated Texture Coordinates and the Box preset found in the Image Texture node. The scale values on the Mapping node determine how much the texture is spread out. You can adjust different ones until the texture displays to your liking. There is also a Bump node to make the plants look less flat. If you so desire, you could also look into the Displace modifier for additional bumpiness. All of this info is fed through a standard Diffuse BSDF shader.
I found a simple leaf texture on textures.com. It is seamless, so you should not be able to tell where one iteration start/ends. You can simply download a low-res version here:
Lastly, this is an example of how the texture might look on your maze.
Hope this helps and happy Blending!
