try putting the fx into a separate fx-file. this things happen when to much shadercode is inside the wdl/material

//	FFP  Terrain MultiTexturing Effect

//

//	By:  Eric A. Hendrickson-Lambert (Steempipe)

//

//	Rev. 04.05.04.1  

//

//	Description:

//	Using 2 tileable textures and an alphamap for blending.  

//	This code uses (2) passes because more than 2 stages would be needed

//	for 1 pass.  The First Fallback Technique is just a 2 stage 1 pass but

//	has the transformation.  The second fallback has no transformation.

//

//////////////////////////////////////////////////////////





// A tileable texture

//bmap grass = <tilegrass.bmp>;





//RGB Channels are blank

//The A channel has the blending weight (pattern)

bmap blendmap = <blendme.tga>;



// A tileable texture		

//bmap sand = <tilesand.bmp>;

   



function mtl_terraintex_init()

{





//bmap_to_mipmap(mtl.skin1);

bmap_to_mipmap(mtl.skin2);

//bmap_to_mipmap(mtl.skin3);



//

// Adjust the texture transform to do some tiling of the textures

//

mtl.matrix11 = float(18);	// default u scale 

mtl.matrix22 = float(18);	// default v scale
