Does T3D use clipmapping for terrain like TGEA does?

Curious about T3D terrain texturing. Is this based on clipmapping?
I found basetexsize and lightmapsize, but no reference to configuring clipmapping.
Is basetexsize for the whole terrain or each 256x256 section?

Posting a follow up in case there's a search in.
No, there is no clip mapping in T3D. The terrain texture is a single image with extruded mipmaps, created on the fly from the originals using a blender. It is cached so it doesn't constantly get recreated.
This technique means that block size has a strong effect on terrain texture quality. The larger the block, the more the terrain texture is stretched. Using a detail texture is very important.
