Decal questiion

<< < (2/4) > >>

Steve:
Here's an ART rendering of all texture blend mode + alpha mode combinations.

jbskaggs:
Following both of you gentleman's advice here is the result:

The sphere s two spheres-  one sphere with graphic overlaid 1 unit over the blue sphere.  texture set to decal final in ambient and diffuse layers.

2nd image is a cube with the same texture settings.

I think they came out well.

jbskaggs:
How does one calculate the needed texture size to wrap the sphere without repeating pattern?

Say you have a 128pix sphere would it be: A=4'pi'r2  or square of 4*3.14*64*64 which would be 226x226 texture?

Am I thinking this correct?

Steve:
It's not the size of the texture that matters, it's the texture coordinates assigend to the faces of your model. Anim8or assigns texture coordinates such that any texture will wrap around perectly.

jbskaggs:
So then on my end how do I create a texture that does not repeat on a sphere?  Like a world map-  it wraps once and is done? Sorry for being dense
