Maxwell Render | Official public forum

Here is a render of a lobby I was working on for a few days for my office. It worked well for our presentation but now I want to do some creative post-production work to it for personal use. I think it is a little flat right now and could use more depth and texture. Any suggestions?

Greeble the wall with large shallow boxes(10in max in the Z direction if the wall is the xy plane, all intersecting and all slightly out of square. Smooth all edges for bonus points.

Then use a mostly diffuse and white cement texture. Sublime, ...beautiful.

Then say, 'Get outta here, ....you do it.' lol....
