Transparent Terrain Shader help please

Hello,
I’ve been trying to install the terrain transparency shader from this link:
http://wiki.unity3d.com/index.php/TerrainTransparency

But so far I can’t do it.

I have created a transparent image and created a material and applied the shader (given in the link above). BUT when in the terrain paint editor, it will only let you add/edit a TEXTURE! There is no way to add the newly created MATERIAL.

Can someone tell me what I’m doing wrong please? The shader I have copied and pasted (link above) throws no errors, The texture I created is a transparent .png The material i have created is using the transparent terrain shader (link above) but the terrain editor only lets you add TEXTURES.

please help if you can.
thanks

If you select the terrain and select the settings tab(cogwheel icon) there is a Drop Down menu under the name “Materials” . You can set it to custom and drag in your own material that is using the custom shader.

Thanks for that suggestion, but after having a fiddle that does not seem to work either.

I’m wondering if anyone has got this script working by following the instructions if provides? OR can anyone else get this working by reading and following the link above?

thanks
