Can't get shading feature to work?

I’ve loaded a few shading filters but when I save changes and view the game it doesn’t change the shading.

Any ideas on how to fix this?

Thanks in advance.

You’re probably not loading them correctly. If so, it’s nothing to be ashamed of, it can be unintuitive at first.

From the menu, you go to options > shader options. Once there, you can use the ‘load shader preset’ option to load and immediately apply a cgp preset file, which contains a multi-pass shader. If you want to load a single-pass shader instead, skip that option and scroll down to the ‘shader passes’ option and increment it from 0 to 1. It will open up some more options. Where it says ‘shader #0’ you can browse to any standalone Cg file and you can apply a specific scale factor and/or filtering method to that shader pass (both of these are usually fine/best with the “don’t care” option). If you want to add additional passes, you can increment the ‘shader passes’ option again and add more Cg files.

When you get everything how you like, scroll up to the top and hit ‘Apply shader changes’ and your settings should take effect.

If you were already doing it correctly, then something else must be amiss and we’ll need a log to know more. To get a log, launch from a command line with the -v or --verbose switch and copy/paste the output to somewhere like pastebin and then post the link here.
