multitex or layers

…Instead of multitexturing do you think is a good idea to use different polygons layers (everyone with different texture) with blending?..if I use multitexturing can I use lighting?..thanks

Using multiple layers (aka multipass rendering) is very limited compared to using multiple textures and one layer. There are more ways to combine two textures than two layers. Use multiple layers only if you can’t use multiple textures.

And yes, you can use lighting with multitexturing. It’s just a matter of setting up the texture environment correctly, which can be tricky sometimes.
