Clear glass appearing black Autodesk Inventor 2015

[dsoer12]

Hello everyone. I have an issue that I hope someone can help me with.

I am trying to make a stack of glasses and take a screenshot using ray tracing. However where you can see through both glasses at once they turn black, as shown on the attached image.

I am using Autodesk Inventor 2015

Material: Glass

Appearance: Clear

Thank you.

first of all, use showcase material "clear glass"

then:

try to rise the trace depth, under file -> settings -> performance & quality

and play with the refractive index in the glass material properties

So your suggestion is to move the file over to Showcase instead of Inventor?

I already made a nice rendering using Showcase, but was hoping that I could use Inventor for quick visualizations.

Not a surprising suggestion given that this is a Showcase forum... the Inventor forums are here.

LOl sorry for the wrong answer 🙂

No need to apologise - it's the inevitable result of questions being posted in the wrong forum, something which seems, sadly, to be on the increase. I wish I knew why it was happening - it's only been a problem for a few months, prior to that it was quite rare.

honestly, i think it's because there's no big tittle stating "showcase forum", nor a layout similar to the other community ones (eg VRED http://forums.autodesk.com/t5/vred-general-discussion/bd-p/2057 )..

That's partly because there's 2 sets of forums - those which used to be accessible only from The Area (those under the "Media and Entertainment" header), and the others. However, this problem is comparatively recent - long after the Area forums moved here.

Hi Dave,

glasses in general are quite complicated materials due to their phisical characteristics (refraction, diffraction, etc)

You can obtain some results with Inventor, even without raytracing.

For better results you have to invoke and use other software, as 3ds Max or for example Showcase, much easier and quick for use and nice results.

I will attach here the showcase scene, just typing the key "R", raytracing will start.

You can import your Inventor model directly in the scene.

Good luck!
