Architectural Materials

[jtseaman]

Hello,

 

I've just completed this rendering and I've noticed some jagged edges on the reflections. I'm using Radiosity and the Scanline renderer. My materials are architectural materials and I'm using the presets. I'm trying to get the floor to look like a high-gloss white epoxy so I'm setting the diffuse color to white and using the gloss paint preset. The reflections have a bit of a jagged edge to them though. Is there a better way to create this material? Also, I would like the reflections to be slightly wavy to appear more realistic for an imperfect troweled epoxy floor. I was thinking of trying a bump map...any suggestions? Thanks!

 

Also, I would love any other critiques of this rendering.

nice image for scanline...

 

let me have a think about the material issue and i'll get back to you (i'm not able to work in VIZ/MAX right now).

 

i don't think a bump map is the answer for reflections - isn't there a reflection map slot for architectural materials ?

 

or maybe it is just a resolution issue, or anti-aliasing settings ? i've found most architectural materials to be pretty good and not much need for tweaking.

 

on another point - what is up with the bench ? it looks like a hollow batt insulation hatch pattern (no offence)

Thanks for checking into it. I've attached several pictures of the effect I'm trying to achieve with the floor. I love the reflection of the elevator on the third epoxy floor image. The wavy part on the bottom looks great and shows more realism since epoxy on concrete is not perfectly level.

 

I rendered the image at 2250x3000 so I don't think it's a resolution issue. I didn't think it would be an anti-aliasing issue either since the other angled lines are very straight. I've attached a close-up of the rendering so you can see the problem better.

 

No offense taken with respect to the bench...your description of it made me laugh. Check out www.amplesample.net it was a design using carpet samples for a competition I entered.

 

Thanks again!

At the material, I turned on local supersampler and left it at the default and the problem cleared right up.

mia_material (architectural) is great for interior scenes. It computes things such as glossy reflections way faster than regular phong, lambert, blinn etc... When i do interior scenes, i usually use nothing else than mia_material. It allows you to create physically correct photorealistic material. Theres no need for presets when you handle it. Just practice a little and you will get a grip of it fast. I can make physically correct glass, gold, chrome, washed chrome etc... in just a few seconds.

 

Hope it helps.
