Working with $dudvmap - Developers

I just want to know how to make dudvmaps work. If anybody here has used them before I'd like to know how you made them and got them into source.

[QUOTE=glarkon;49103511][url]https://developer.valvesoftware.com/wiki/Du/dv_map[/url][/QUOTE] I still don't get how to use them though.

[QUOTE=tinak;49103526]I still don't get how to use them though.[/QUOTE] Well according to the wiki it's defunct and has been replaced by the refract shader. What are you using it for?

there's a magnifying glass on the sfm workshop. take it. the refraction got flaws. find out how it works correct. or read the description. ;)

Refract { $normalmap ... $dudvmap ... $refracttint "[1 1 1]" $refractamount .2 }

[QUOTE=tinak;49105657]Even though it's still asking for a dudvmap... Refract { $normalmap ... $dudvmap ... $refracttint "[1 1 1]" $refractamount .2 }[/QUOTE] "The pattern of refraction is defined by a normal map (DX9+) or DUDV map (DX8-). May be animated." It can be a normal map or a DUDV map.

[QUOTE=tinak;49105806]So just plug in your regular normal map then and not bother with the old stuff?[/QUOTE] Yeah, there's also a $refracttint and a $refractamount that seems like it'd be useful
