Hi guys,

I'm working on a scene that has tons of concrete so I'm trying to get the materials to be set really nice. I wonder if someone could give me suggestions of settings for mental ray architectural material (I'm using Maya, mia_material_x)? I tried to set up 2 types of concrete:

First was polished, shiny - as the one seen on this photo:

Second one was not shiny at all, almost powdery look, kind of like these ones:

If someone could point out the surfaces features and how to mimic it with mia_material I'd be VERY grateful. What I managed to get was just OK but didn't look quite the same.

I'm pretty confident with textures, it's just material settings.


Thanks A LOT in advance!

Hi caro,

To get the polished concrete, give it some reflection and adjust the glossiness value to give it a blurry reflection. This will be your basic polished concrete. To enhance it further, put a specular map in reflection slot, or you may manually create a glossiness map to give it different level of blurry in the reflection.

Second one basically you can achieve without doing anything. Simply put your texture in the diffuse slot will do.

Thanks tecsun!

That's pretty much confirms what I though might work so I have a lot more confidence in the idea right now. Thanks again! Much appreciated.
