It is better to UV a surface in larger contiguous pieces. In your example, the top of the island will be grass, so it should be mapped as one…
Hi there. I am new here and would like to ask some questions. I am still a rookie at 3D work and I would be very happy about your help. Do anyone know a good tutorial about when to use tiled textures and when bespoke ones? And maybe some examples how the Uv would look like? Because I work on an environment art and want to…
