multitex fragment shader issue for different sized textures

[pitbool]

Jeff, just letting you know that I was able to solve the problem, with the help of Jorge, a Worldviz 3D artist. The baked texture in the terrain was a blend of two textures and a masked texture. I think he used the "render to texture" feature in 3DS max to export all of it to a single texture, which I used instead of retrieving the texture1 from the terrain at runtime. Then I blended it using the algae texture in the unit 1 of multitexturing.

Thank you.
