This mesh table comes as shown, with the shadows. What you see is what you get.
The table top is white marble with black flecks and has a slight shine, the legs are white. I took care to hand paint a realistic shadow for the legs and table, not a fuzzy indistinct blob of a shadow that most furniture has. What you see in the photo is what you get.
Permissions for this table are copy / modify so you can tint the legs and the top separately for different effects. I deliberately kept the legs white and the table top pale so you could do this. Land impact for the table, including shadows, is two as is, if you stretch the table you make increase land impact.
If you have the table on a dark floor or against dark walls and you think the shadow is too pale, you can decrease the transparency of the shadows in the texture settings to make it darker. If you don't know how to do this there are building classes teaching the basics inworld.
Nice work!! :)
