2min render time on Easy 03 Low+ :!: ;)

This is with all Studio Light Spots turned OFF in the scene.
Only HDR lighting with settings as shown below.

Even if it takes you 4.5mins, I'd still say it's quite a good render time... and nice render. :halo:

takes 4.5mins on High setting on this machine.

Hey guys,
Heres a new render of one of my previous models.

Kinda cheesy, but I still like it :D

Cheers.

:^: That's a "keeper". I really like the floor reflection, and it describes really well your intended "look" of the piece. It's excellent work, beginning to end.

Which render setting? (curiosity)

I dont remember... easy 9 or 10.

With a very small bloom effect and little less vibrance It looks great!

I need more skill in photo editing... :x


Fletch, how would you do to get some reflection or highlights on the white doors? Should I add a spotlight?

Thanks.

needs a more directional light, because they are white and reflective, adding light would not likely help (but who's to say?). a dark surface for the angles pointing left, and a light surface for the angles pointing right may work. (or just some quick highlights in photoshop could work fastest and gives ultimate control)

or just try diff. exposure or diff. HDR

also using a black and white line export from su and blurring it to create a sort of fake ambient occlusion may work nicely. see example here.

New test.

I am trying to do a white oak top on a brushed stainless steel frame.

Does it look like what it is supposed to be?

Cheers.

it does to me. :totgm:
but if you have a photo of something you are trying to match, it would help.

regardless, one thing that will improve renderings greatly and is easy to do, you will notice in product photography that they will have a dark to light gradient on the background, this helps highlight the product.
example here:

A vase or something simple decorative sculpture on the table to provide a little "something" could be an idea?
Or a more detailed vignette of a corner or something inlaid on this view?

fantastic video tutorial! :arrow: Check out these backgrounds behind the models.

Hey Fletch,
well... I dont think it is the background... I was trying to achieve that high-keyish look.

I think I have a problem with my brushed metal mat. It looks like some kind of silver powder coating. :?

It is probably again related to the lighting... :wall:

Anyway, I am trying something else, I'll post the result.

Cheers.

metal is extremely sensitive to what it's reflecting.

Finally I tried another hdri sky and its rendering now. I think it will be better.

I am wondering now what is the difference between the metal and brushed metal template.

I am guessing that the brushed metal template has more blurry reflection, is that right?


I tried many different stainless steel mat setting and tried to compare my results with actual steel. I think the most important things are:

1- blurry, but at the same time rather hard, reflections.
2- diffuse color.

Unless it is a very close detail, theres no brush lines visible. So if the brushed metal can take care of the blurry reflections, I think theres no reason to use a bump map.

Anyway, I'll post soon a new render.

Cheers.
