Procedural weathering for large structures?

[-andrew-]

Hi everyone-

 

I realize there are a few subforums here for rendering (and I have both Maxwell and Thea) but wanted to ask here because of the nature of the question, especially because I don't know if either has a solution...

 

Basically, I'm hoping to find some method of realistically weathering large-scale materials, for now specifically concrete and other building materials.

 

The idea is that I'd like to "apply" weathering to large structures without having repeats in the texture.

 

 

Any thoughts?

 

Thanks,

Andrew

Andrew,

 

How large will your final rendered image be?

I would approach it in two ways if you are using Maxwell to render.  First is to download or create some very large grunge maps.  There are a lot available if you search.   Then use Maxwells ability to layer dirt maps and corrosion by assigning different levels to each layer.  Once you have something fairly convincing I would leave the rest of the dirt for post processing in Photoshop, again using large grunge brushes.  I have brush sets that range from wet footprints and water damage to tire tracks and drips.  In Photoshop to make them convincing I often use a drop shadow effect for depth.  Lots of tutorials online on how to do dirt.

I was going to recommend 3dCoat... but I see you already found a good solution there with Leaks PBR. Cheers! 3d Coat is a great companion for FZ.

Hi, and a belated thanks...

 

Out of curiosity - is there a tutorial for getting 3DCoat-painted objects into 3DC then back out ot FZ for rendering with Thea?
