Is there a way to make a war3 texture brighter in a model without importing another?

[Lestat(br)]

I need to make the Doodads0.blp texture brighter to my Sun Workshop model. But I just don't know if this is possible.
I use Autodesk's 3dsmax 9.

Thanks in advance.

since you are using dex, you may have to use MDL editing, a good technik for bighting a textures, is making a white/gray layer and then adding an additive layer over it.
