Trying to learn GLSL (Earth Shader)

I’ve been trying to get into GLSL lately and so I found this tutorial.

TLDR; The tutorial illustrates a shader to render Earth something like this.

I’ve made a .blend accordingly and attached it… because it doesn’t work, and I can’t figure out why not : S

I’m not getting any errors in the console : S

I thought the tutorial might be outdated, but, it’s not even a year old : S


Edit_00: One of the reasons I want to learn GLSL, is so that I can start tinkering with these files.


GLSL_Globe_00.blend (1.05 MB)

GLSL_Globe_00.blend (1.07 MB)

: D Thanks a lot!
Hmmmm… obviously some things I’ve misunderstood, much to learn. I’ll keep at it ; )
