ARB unit 2 realtime updating

Hey, I am useing GL_TEXTURE1_ARB. I can’t update the texture binded to it in realtime. Allthough, I can update the first texture unit any time I want. Does any one know the problem?

Greetings, Michael L.

Without any more information, no, I don’t really know what the problem is.

Are you sure you’re calling glActiveTextureARB(GL_TEXTURE1_ARB) before the bind texture?


Yeah. The wierd thing is, I am sure the code which changes pixels work. Cause else it didnt do it in the init. And for texture unit 0 its ok. So its a complete mystery . Maybe I can fix it in the future somehow…

How do you “update” the texture?
