OTOY Forums

I did some industrial components showcaseing for a new brochure for a client. They do air ventilation tech for all purposes. Pretty techy stuff. They gave me CAD data to work with.
Was nice with Octane. This was a pre-final version. It was to realistic for them so I had to delete logos and make the electric boxes grey. But I liked this one more so I think I share. Some grain because I didn't render them out. Colors needed to fit their CI.

The room is the final version. All rendered with Pathtracing. Small images 30min, room a hour or two. 2x 580GTX....

Very nice stills

the interior shot is super!, all the conditioning components seems real.
The other shots seems absolutely photos!!! (are you sure they aren't? )

Congratulations!

Why do you not use PMC kernel (new) despite your 2 x GTX 580's (= very good performance)? But this kernel is recommended. I like too and always use it.

Thanks guys!

I choose a kernel depending on my scene. There was no need for PCM. The room has an open wall and the parts uses a HDR image. Mostly I even use the basic kernel and try to stick with basic materials.

the component renders look great! some anti-aliasing issues with the background though? difficult thing to fix I guess

wouldn't the office chairs have chrome legs..?

No issues with AA. I just rendered with alpha and didnt put a background in the preview for client. So it looks a bit jagged. On finals all looks fine. You only get AA issues if you render with alpha in Octane and save to .jpg and not .png afterwards.
The office chairs dont need to have chrome. Mine even don't have chrome legs too, hehe. And it shouldn't distract the view from the equipments at floor and ceiling. So I've choosen more brushed looking metals.
