Indigo Renderer Forum

Hey guys..

I have been trying to render a Gio bottle, but i have run into a little problem..

I have 2 different renders here.. one is just a glossy transparent for the bottle, but in the second I have tried to add a little sss but it turns the inside black..? Any ideas to why that happens..?

The liquid inside should overlap the inside wall of the glass - you can see a good example at the end of this document: http://www.indigorenderer.com/joomla/in ... &Itemid=62

Also check your material precedence. Air is equal to one. Your liquid should have the highest precedence, followed by the glass.
Drinking glass example: glass 10, drink 11, ice 12

And, as always, check your normals.

Thanks Phr0stByte

It was actually a stupid normals problem.. The precedence was set right, but the normals on the inside of the glass was pointing outside.. stupid stupid me.. Will post the updated render when it has cooked a bit longer.. Things are SLOW on this little laptop..

that doesn't sound right to me.

shouldn't it be:
air < drink < ice < glass ?

ie: drink displaces air, ice displaces drink, and glass displaces ice.

Yeah, I might have wrote it backwards.... But, problem solved anyway

I have plastic tube > liquid > glass

Isn't that correct..? It looks that right anyway..

Yes, that is right. I indeed had things arse backwards - not unusual.

I am actually doing a scene now where the test render did not show the objects, but showed the shadows cast by the "invisible objects. Turns out my normals where inverted on those objects. Still have to do another test to see if its right now...

Think it should be tube > glass > liquid or glass > tube > liquid

hmm are you sure..? I think this looks quite right..

Still have to work more on the materials though.. The text should be much clearer and the glass is still not quite right...

I'm liking it Keep at it

I am sure... you need to set glass > liquid for so that your glass replaces the overlapping parts of the liquid... the way you did it is wrong as the liquid replaces the glass that way...

Okay thanks.. Changed it now.. This one is out of focus but i kinda like the look of it...

It's kinda cool, yet we can't see the text at all.

I know I just can't seem to get it right... another try:

Well that definitely looks better. But I'm puzzled as to why the whole image still looks extremely grainy at such a high spp count. I mean at 1259 i would normally expect the image to look clearer.
