Hey, I'm looking to make some materials via lua
meharryp posted some code that, if I understand it correctly, takes a screenshot of a 2d cam of the original texture, draws on itl, then makes it into a new texture by saving it to the disk and reloading it as a material
[url]https://facepunch.com/showthread.php?t=1548067&p=52492951&viewfull=1#post52492951[/url]
Is this the only way to do it? Is there a better way?
Ideally I'd like to draw arbitrarily over another material, if that makes a difference
I'd appreciate any help here
It all depends on what you want to do.
First of all you might want to take a look at this half-finished (or less) guide that I started writing before abandoning: [url]http://wiki.garrysmod.com/page/Materials_and_Textures[/url]
It's important to understand what's what, and understand what you actually need to do.
You can create a brand new [b]texture[/b] or acquire an existing one with [img]http://wiki.garrysmod.com/favicon.ico[/img] [url=http://wiki.garrysmod.com/page/Global/GetRenderTarget]GetRenderTarget[/url], which you can then put into [img]http://wiki.garrysmod.com/favicon.ico[/img] [url=http://wiki.garrysmod.com/page/render/PushRenderTarget]render.PushRenderTarget[/url] to draw into it or modify it.
You can acquire an existing [b]material[/b] with [img]http://wiki.garrysmod.com/favicon.ico[/img] [url=http://wiki.garrysmod.com/page/Global/Material]Material[/url] or create a brand new one with [img]http://wiki.garrysmod.com/favicon.ico[/img] [url=http://wiki.garrysmod.com/page/Global/CreateMaterial]CreateMaterial[/url], which you can then modify using [url=http://wiki.garrysmod.com/page/Category:IMaterial]the various material functions[/url], most importantly [img]http://wiki.garrysmod.com/favicon.ico[/img] [url=http://wiki.garrysmod.com/page/IMaterial/SetTexture]IMaterial:SetTexture[/url].

You can open materials with this after you've written then to the data folder
