Bump Mapping Created 18 years ago2006-08-23 00:08:46 UTC by davideo59

Can anyone help me out and post a good tutorial on how to bump map a custom texture and then add the "shiney" feel to it? I looked at HL2world.com's tutorial on it and it wasn't very well written or I just didn't understand it hehe (and the pictures wouldn't load :cry:)
Thanks

hope this helps

Thanks but that just leads to the HL2World tutorial on making bumpmapped texture, to which the pictures (that would make it so much easier) don't work ><

I was writing a tutorial for this, but put it off for other projects.

Heres a quick description:

Assuming you know basic material creation:

Use NVIDIA normal map tool to alter image for the normal map.
For the shinyness:
Create an alpha channel on the normal map image. Duplicate the normal map, and change to greyscale. Adjust. (white is full reflection, black is none) ctrl a to select all, copy and paste the greyscale in the alpha channel of the normal map.

Save as texturename_normal (drag onto vtex)

Place texturename.vtf and texturename_normal.vtf in your material folder that you create.

Set up your .vmt like this:

"LightmappedGeneric"

{ "$basetexture" "yourfoldername/materialname"
"$surfaceprop" "rock"
"$bumpmap" "yourfoldername/materialname_normal"
"$envmap" "env_cubemap"
"$normalmapalphaenvmapmask" "1"

}

Thats it. Thats a VERY VERY sloppy description, but it should help.

I also suggest these links in the valve wiki:

Try the one on Interlopers.net

Does interlopers have a version that doesn't require and nVidia program for us who use ATI cards?

Erm, the nVidia program will work for all cards. It's a plugin for Photoshop...

Can it be used with Paintshop? If so, should I just google it or somthing?

It can but I had very little (and I do stress the word little) success with PSP 9. Dunno about other versions.

Ahh, well regardless, PSP7 continually crashes for me in the exact same spot every time so whats the use?

Well, it's designed for Photoshop. Here's hoping it works for the Mac version.
