Tried to google it.

Wrote some functions for a project to use Uv's referenced from the bottom left, however, when I started a new project for some reason they are being referenced from top left. I know there is a function that sets where UV's reference stuff but I couldn't find it in google. Any help would be appreciated.

So you want to flip uv vertically?
You can use


 tc.v = 1.0 - tc.v;

uv (0,0) is the lower left of the texture in OpenGL. If you say its getting it from the top left, you're probably loading the texture upside down.

Ah that makes sense I did switch the api I used to load the textures. Thanks, completely forgot.
