View Full Version : image size rules
Sorry for my general question but I'm newbie in texturing.
I read Leigh texturing tutorial and there are some rules about texture size. But I still don't know if I should stick with for example square or rectangular size. Let's take for example head texture. It will look different when using square resolution and rectangular am I right? Oh..:banghead: :banghead: I'm really confused there...maybe someone here could explain me more specific how does this whole resolution thing works? I know that bigger texture means better quality but this whole square and rectangular thing how is working?

The shape of the image used depends on the shape of the model you are applying it to :)
UV maps are generally generated in square templates, so they are usually always square, that's all :)
I think you may be getting confused between image shape (as in image dimensions) and image file size though...
maybe I didn't explain correctly what I mean...here are images:
One is Unwrap UVW
and the other is texporter image with resolution 800x600 as you can see it's size is wrong

The important thing for accuracy is that you crop the image according to the template that your unwrapping app gives you :)
In the case of Textporter, it seems as if the program exports the image as a rectangle, yes? Then keep it that way :)

I think using cube textures is just a habit. For games, it's usually mandatory. In most other cases, a non-cube is perfectly "legal".
In the example given, the 800x600 is not exactly wrong. In UVW Unwrap, the space just happens to be a cube. However, it looks like a texture hasn't been assigned just yet. With that as it is, I bet there will be some stretching (horizontal or vertical - I get them mixed up sometimes). So, to "fix" the stretching that will probably occur with a cubic map, the final texture dimensions were stretched horizontally when exported from Textporter.
Man, this is tough to explain.
