I am using the Shader from the Wiki, and I get this message:
Error in effect:

Heres the code I am using:
In the main wdl:

my.skill44=float(10);

my.flare=off;
my.transparent=off;
my.material=mat_terrain_multitexture;
}

in the multitexture.wdl:
material mat_terrain_multitexture

drop the ".tga" from your entskin declarations.

texture entSkin1.tga -->> texture entSkin1

edit:oops, shoulda cropped
No errors just...
entSkin1 is my dirt texture
entSkin2 is my Grass texture
entSkin3 is my alpha map

Is your blendmap in the Alpha channel of entSkin3??

huh?
I haven't read the C-Script manual, so i pretty much understand the basics, so please, be simple with me
heres the what skins im using

So... you need to have the blendmap in the Alpha channel of the texture. Not in the RGB channels for your code.

You can try this file for entSkin3 and see if you have any better luck. And then maybe see what I am talking about.
11kb file

It just made everything black. I'll try to explain what I did and see were im going wrong...
I inserted entskin1 as a skin on my terrain, then i made a new layer thingamabobber and inserverted enskin2, then made a new layer thingy again and put on the black thing you gave me, and attached the terrain behavior. Did I do something wrong?

Anyone have any ideas?

Time is limimted...

Could you post a small level that replicates your problem. It would be quicker if I could run that and see what may be up.

Also, put your Gstudio, DX, and Vid Card specs in.
