Contrary to popular belief, we are not all-knowing-all-seeing magical beings!

If you want help you're going to have to provide lots of info. Like what is your hardware, what is your operating system, what version of GZDoom/LZDoom/whatever you're using, what mods you're loading, how you're loading it, what you've already tried for fixing the problem, and anything else that is even remotely relevant to the problem.

We can't magically figure out what it is if you're going to be vague, and if we feel like you're just wasting our time with guessing games we will act like that's what you're really doing and won't help you.

[Help] Shadow maps not appearing

It appears shadow maps do not appear despite the fact i have a version of opengl that can support them, that version being 4.2.
is there an explaination for this?

It's probably because your version of OpenGL does not support all features for them. What's your OS and graphics hardware?
This requires features from GL 4.4 which may be supported through extensions on older versions but are not guaranteed.

The card can do it but apparently you are not using the latest driver for it, because that should support OpenGL 4.4.

Be prepared for some disappointment, though: That hardware is nowhere near powerful enough to handle shadowmaps.
I had been using a Geforce 550Ti which is a lot more powerful until earlier this year and even on that card I could barely use the shadowmaps. Even on the lowest possible settings they caused frequent lag on medium sized maps or when the BFG was fired.
