OpenGL Unbind texture

Question

I have a huge list of 2D Textures that I load each time a map loads (Depending on the map and it's contents). I'm looking for a way to anyhow unbind a bound texture to reduce usage of memory. The bind texture function works perfect just don't see any function to unbind some ids or all of them.

Answer 1

try

glDeleteTextures(1, &texID)

This should remove texture from memory. Before that call be sure to unbind currect texture by simply calling:

glBindTexture(target, 0) // << default texture object

glDeleteTextures spec
