Thanks Alex for your feedback , i've fix the ashtray the glossiness was too low. For the table it's essentially photoshop, for this king of thing i usually place and adjust the tilling of a basic texture directly in 3dsmax, when i'm happy i do a "render to texture" unfortunately corona doesn't handle this so i've to switch to a standard material and scanline rederer. Then in photoshop i've duplicate my wood texture and make it one dark and one brighter with a mask for the wear effect , and finally add some white touch with a custom dirt brush with low opacity for the dusty/washing effect .
