Hi,
I want to make a flat terrain (Plane object) for ground in a 3D game.
The size I want is 2000X2000 px and I want to place a texture over it which may need to repeat.
In Blender is there a basic tutorial I could follow for something similar.
When I create a plane object it isnt displayed along X/Z axis by default.
A few points
You can rotate the plane to be along the X/Z axis by selecting it and rotating it 90 degrees around the X axis. To do this you can use the keyboard shortcut R X 90. I’m not sure why you’d want to do this for a terrain as this would make a vertical plane not a horizontal one like the default placement
Giving it a pixel dimension is pretty meaningless. If you want it to measure 2000 x 2000 units you can input them dimensions by pressing N to show the objects properties. You can then input a specific dimension.
3d objects are not sized in pixels. You can map any size image to any size object - you don’t have to make a 2000px object to fit a 2000px image, for example. I can map a 4096px square image to a 1 blender unit scaled plane. Or I can map a 32 pixel square image to a 10,000 blender unit plane, and then tile it, or not.
