Very hiper mega realistic.
Good work.

jeffleeismyhero - that might have something to do with the reflections from the glass

That's it

Thanks to all!

it sounds likely thomas, and it's a great idea, we should all do that from now on.

If you're that patient. I've tried to remove my black dots, but gave it up after an hour of retouching. Man, thats even more boring than watching a level 25 image advance to 26...

how have you done the metal?

Gold
Roughness 0.2

Hi iker,

very nice images you made! Would you mind giving away the name of the HDRI you used and what settings you used for converting the TIF file to MXI? Many thanks!

Regards,

I used "Apt-probe.hdr", and I can't remember exactly what parameters I changed, I remember to change the intensity but sorry I can't remember how much

I did some tests with the "Power" of the emitter, and at the end the emitter's Power was at 1000, but I guess all depends in the size of the mapped sphere, the intensity of the MXI,etc....

Awesome - photo-real

Thanks for the info!

Thank's a lot for your answer and the explanations!

Wonderful images. Great.

I have googled and found the HDRIs. Here the link:

Iker, today I have try a LDRI Sphere too, but it need endless. After 6 hours and SL 16 and 320x240 it is very noise. How long did you render? Do you have any suggestions. The quality of your images is so perfect. How big is the sphere and how big the clock? Do you have used a blurry HDRI? Do you have made a polygon mesh from your Sphere or do you use a "real" sphere? Could you post a screen shot from Rhino? ...

Here are some screenshots:



The rendertime for the big one (I'm going to post it in some minutes) was 600 min at 720x900.

Camera settings:
Shutter=60
FStop=5.6

The clock was modeled in real size (30 cm diameter) and I converted the HDRI in tga, and then in MXI increasing the intensity (not blurry HDRI).
As you can see it is a "real" sphere trimmed to get some dark parts of the MXI out , and to try to reduce render times, and the only trick I used was render the image with some different lights ( just rotating the sphere with the MXI mapped ) to get the best illumination.

Thanks for your interest

Iker,

thank your for the deep insight. Interesting setup. I make a first test with a sphere here, and after some adjustment of the intensity and gamma of the HDRI map, it works good.

Here an experience from me. Maxwell only support LDRimages. But I get good results, if I had open an HDR image in HDRShop and change the brightness of the image like in the example of the selfmade HDRI (here LDRI) and than I saved it as LDR TIF. After I open it in MXI viewer, I was wondering me, how much lighting details stay at the low dynamic range image. If some body like, open my example and change the intensity. Fazit: convert HDRI to dark LDRI and it bring much details.

cool image iker, very photoreal, and thanks for teaching!!

sorry about my english ...

great work ... just one question .. if you converted an hdr image into TGA, then i assume you can use any halfdome image to create the mxi texture ? because if i remember well you lose the hdri information when you convert the image to tga ...

Also that means that you can use any image created for instance with a digital camera and a stitch program, or any other half dome jpg image ??

Thanks a lot ...

Yes, ofcourse. You can use ANY image, doesn't have to be a stitched panorama. He just used one in this case because he wanted to apply it to a sphere.
