light and material study

[JeZ]

maybe it is some weird optical effect that I dont understand...

If you have rights to it, please post model, and perhaps we can help.

I dont mind sharing my file, except it would be the proof I'm not good...

Im using the twilight studio scene and the twilight scratch texture. Should I post it to the Resources forum?


I tried to reverse the color plane faces, but it did not worked.

Heres an updated version of that scene. Same thingy on the drawer fronts and obviously crappy stainless steel mat (I have done pretty much the same as in your example )

More work needed... yay!

Cheers

wherever you wish, is fine.

we can take a look.

what's wrong with the stainless steel? do you have an image of the 'look' you want? There are thousands of different kinds of stainless.

I rebuilt some of the glass panels and then rendered the scene without the cabinet under the glass.

There is definitely something wrong with the color plane.

Heres the skippy.

Well, That look more to me like some kind of silver looking metal. The appliances or countertop look would be good enough, but I would prefer to be able to render it more like custom furniture parts ( handmade with abrasives), but that would only matter for closeups.


Thanks you Fletch for your help.

I think I fixed the the painted glass problem by pushing just a little the color plane into the glass.

I'll post the result later when the render will be cleared.

Ok, first glance with the model:
avoid 2 planes sharing the same 3D space... this is especially the case when one plane is supposed to be paint, and the other is glass.
Just like 2 objects cannot occupy the same 3D space in real life...

1. First thing I did... hide all lights and reflector planes... keeping only the furniture and the background curving screen visible, create a new scene.
2. Next: Download the free Apt-probe.hdr
3. Next: Be sure Sun is OFF, all other lights are OFF, and set Sky to "Spherical Sky" and load Apt-probe.hdr into the image for the spherical sky.
4. Set Sky to "1" brightness.
5. In Render dialog, rendering prelims with "Prelim" setting... and gamma to .5, exposure to 2, setting camera to "pinhole" (Set F-number for final image if you desire Depth of Field effect, but for testing prelim images, it slows down preliminary rendering drastically)
6. Delete all the little floating 'paint' planes that are touching the backs of the pieces of glass. Move all pieces of glass min. 1/32" away from adjacent geom.
7. Lift whole table up off of floor by 1/16" or 1/32".
8. Try painting just the back face of each pane of glass with your paint color.
9. Set stainless steel material as so:
   • Metal>Silver (not brushed metal template)
   • Shininess> 600
   • Bump>.1
10. Set glass materials as so:
    Alpha "0" ... currently it is "30" and this is too dark.

With HDR, and those metal settings, I'm seeing caustics on the floor next to the table legs with Easy09 setting.

The attached render was with High+
I'll post the Easy09 later.

otherwise, you've done a good job on the model... bevels/round corners, etc.

I think a few reflector planes in the right place - possibly even if they were light emitters could improve the lighting... some interesting shadows falling on the back screen would also be good.

[JeZ]

Thanks a lot Fletch. I did not expected that much.

I will study everything tomorrow morning. I hope I can return the favor someday.

Here's a start on a nice lighting setup using emitters, and eliminating the HDR.
I find the back-painted glass is clearing slowly... especially with HDR lighting for some reason.

I put one slightly warm colored emitter to left - front, and one colder emitter to right-side... I see this combo in studio shots.
