Image textures in LuxBlend - SOLVED

I want to make a lacquered wood material using substrate on LuxRender, but all I get’s white… like plastic, or something like reflective plastic when using bumpmaps. I’ve tried mapping textures everywhere there are “t” slots, but it doesn’t work…
I’m using PNG textures, they are supported, when I use “matte” the texture’s visible.


Edit: I guess it has something to do with the file’s location?
I think I found it! I ticked the A on the exponent thing.
