I started making this little scene, modelled in Maya and I was happy

Untill I started rendering it...

The glass is totally screwed, I think it may be a polyNormal problem in the Maya exporter...
But what is wrong?....... it is always that reflective (IOR around 1.3)
Also the phong and NK materials are very dark.
The scene is containing three Meshlights and a light background color, which not is showing....
Everything is just really messy

(The cake color isn't fixed)

Help!

light background color??i think this is your problem...swich off the back color and rerender...maybe try to light up your scene with only hdri map...make some tests...

Been testing for over an hour... It's not the BG light
And I don't have any .exr images.. Non that Indigo can use that it.
But the glass problem is the biggest.
I'm going to make a super simple glass scene and check...

Here it is..
There is clearly something wrong going on here

It is created in the new Nick way.

IORglass = 1.2 IORliquid = 1.28
One Meshlight, no other light. (6200 tris)

Is this a normal issue? (created by the exporter?)

EDIT: everything is working fine when I set normal_smoothing to False...
EDIT2:

EDIT3: seems like I solved it

EDIT4: Yepp, It's fixed!!

there is no way to model/render liquids in a glass entirely correctly in any released version of Indigo.
Depending on how this new technique works out, the next version should have support for this.

yeah....

It is something wrong with the Normal export anyway..
Not quite sure what it is yet, but I might have fixed it

but there are no problems with your Cola bottle. How did u model it?

This glas is also smoothed, and i can recognize any anomaly. Can you see anything? I think you have problems because environment.

The same problem is on the coke bottle..
I just used a IOR of 1.02

The error is that the normals was turned inside out

I'm going to do one more tests though... just to be 100% sure..

EDIT:
The right one is what the Maya Exporter was creating/exporting before..
The left one is what the script is crating/exporting now
