Title: Metal material advice
Post by: Adam_M on February 12, 2013, 05:40:18 PM
Hello all, new member and keyshot user.

Anyone have any tips for reducing reflections in assemblies with machined and cast parts? I'm having troubles with unrealistic looking parts because of reflections. I've tried bumping up the roughness scale on the machined faces but this leads to unrealistic machined parts/faces. I've also rendered about separate images leaving out some parts to reduce reflections.

Anyone have any tips/tricks or material advice for metal?

Thanks

I'm not sure I understand the issue. What is looking "unrealistic"?

You can try adding a semi transparent layer to the lable part ... I did that once for aluminium to get that slightly oxidised look.

What? - they're too shiny? Have you tried using bump maps?
If you could post a picture or a .ksp file I'm sure someone would be happy to advise.

Sorry for the horrible description of my problem.

I've attached a photo that hopefuly helps.

Can you just make the color darker?

You will need to apply bump maps. Look into the textures folder and apply the suitable texture as a bump map.

If the material is suppose to be "smooth" should I still apply a bump map and just turn down the bump height and roughness?

yes - exactly. For cast you can just the roughness value and increase it a bit. For chrome, just leave at 0 roughness, but maybe change the color to more of a gray. For machined, you may want to try the stainless steel with a light brush from the material library.
