quixel 3do - marmoset toolbag 2 - indigo

[noldo]

Hi guys,
i have downloaded a beta release of the quixel suite, and i downloaded to the following address (http://quixel.se/usermanual/quixelsuite ... do_samples) an example with this program (scifi elmet - beautiful sample).
Then in 3do, or in marmoset toolbag 2.0 (great software for previz), i have imported the .obj model, and i have set all the texture of the sample (albedo, specular, glossy, normal, occlusion).
The result is astounding.
Then i have tried to obtain the same EXACT aspect in indigo (with the same hdri setting), and there are almost succeeded.
But what is the setting for especially specular & glossy map?
For clarity, my setting are:

Obvious phong material
Gloss -> exponent a=1500 b=0 c=0 gamma=2.2
specular -> fresnel scale a=0 b=1 c=0 gamma=2.2
IOR=20

But for an EXACT MATCH?
Thanks!!!

Hi, what tone mapping setting are you using (Imaging>Tone Mapping)? You possibly would like to switch to Linear first. Next thing I would do is changing Quadratic coefficient to 0 and Scale coefficient to 1500, so it would like this:
exponent a=0 b=1500 c=0 gamma=2.2

And the setting for IOR around 1.46 (if we think of the material as a plastic):
IOR=1.46

I have also made a quick test (hope you don't mind for posting it here).
Although I don't have the same lightning. Where is the hdri? Probably in the software?
Must say a great model and textures from Michael Pavlovic

Thanks to all, i'll try the setting you suggest.
I setting the the tone mapping linear!
I changed the hdri in marmoset (same hdri in marmoset and indigo).
