Guide to proper materials for Custom Shader Patch?

[dud]

Is there formal documentation? I have some skins that I want to make look good in the shader's patch.

Among other things I need a list of which color channel (incl alpha) in which *.dds file will do what in CSP. I did that experimentally for base AC, but some things are off now. Some glow and gloss isn't where I wanted it to.

IIRC CSP now uses Stereo's custom shader from the Dodge Monaco as the default. Details on how it works are here:

Thank you!

Thank you!

You're welcome! Note that the the CM Custom Showroom does not properly display the shader; especially the chrome and diffuse-coloured specular features. If you're doing anything more than glass/satin finishes you'll need to view the livery in game to see how it will really look.

I believe red and alpha get switched depending which specific shader you use, mostly because dds compression makes red channel AO significantly worse (and bleeds errors into green/blue depending on software used to compress), it's just that way for better compatibility with normal skins.

DDS is a compressed format? :eek:

Yes, a very lossy one, too.

Leave it to Microsoft to do that to textures.

Remind me, doesn't AC take png files, too? I thought there was something.

Yes, but they are vastly worse for performance than .DDS files in most cases

It technically does, but they’re converted to uncompressed DDS on loading, so vram takes a big hit.

I think I'm gonna check whether GMIC compresses cross-channel when it makes *.dds files.
