How do I use a shader? Iv tryed using the commands and it says "Unable to load shader/ bla bla bla
please help

Go to options and activate the one called shaders.

But one question... Do you have good enough requirements?

Go to options and click shaders. If this doesn't work u need a faster video card

I think this belongs in Support.

go to options and click shaders.

After activating the basic shaders, you'll ahev to use /lws shadername.inc.

To find out the shadernames, go into data/shaders and check the names there.

IДve clicked on the "shaders" button, but when I close the options window, the shaders donДt appear, then I back to the menu, and the shaders are not selected.
IДve tried to input "/lws shadersname.inc." but did not work too.
Thanks

Your video card is too bad for shaders

or you don't have drivers installed for your video card

Read the "Toribash premium graphics" thread under "FAQ" board, it teaches you all you need to know

Thanks
