Problem with textures tiles in Gmax

[hugopiugo]

I've been trying to create a scenery using Gmax, following a tutorial online.

So, I use all the coordinate procedure to know the size of the plane. After making the plane with the right number of segments, I use a Multi-Material to apply the 1024x1024 ground satellite textures.

After completing it here's the result:

This is how it is in gmax, you those textures "gaps"

Here's how it is in the sim

 

This doesn't happen in the tutorial.

How can I fix this?
