I was just wondering if there was a way to set certain shaders ('zane_pain' for example) as your default shader?
For example: I want meatwad_silover to be my default shader so when I exit out of toribash and re-open it, it'll already be opened up so I don't have to go to utils and re-click it again.
Thanks.

just change your shader name to default.inc

This, or add a line to profile.tbs that says

lws meatwad_silver.inc

If there isn't a file called "profile.tbs" in your Toribash directory, make one.
In it, you can put any commands that you want Toribash to run on startup.
You can use any command that you would in-game, just without the slash.
For example, mine looks like

opt altimeter 1
opt speedometer 1
opt blood 0
opt bloodstains 0
opt bruise 0
opt particles 0
ls atmo/src/atmospheres.lua

That really makes things easier for me.
You have my greatest thanks supah.
