What is a texture? An image mapped to 3D surface
In older video games or games like Minecraft, the line between geometry and images is pretty obvious.
In newer games or in visual effects shots though, it’s a bit less clear where to draw the line.
With bigger production budgets and faster computers, geometry got waaaay more detailed. At the same time, there are now new types of complex textures.
So where does modeling end and texturing begin? That's going to be different for every project.
