Hi, i experiencing some strange behaviour with this geometry and glass material
geometry + physical glass material, rendered in maxwell
flipped geometry + physical glass material, rendered in maxwell
geometry + physical glass material, rendered in luxcore
flipped geometry + physical glass material, rendered in maxwell
two glass issues

Please upload a testscene that allows developers to reproduce the problem, and attach some images.

Re: two glass issues
You may need to post the known geometry for efficient help.
Re: two glass issues
Ops, sorry, i edited the previous post and added the file, thanks.
Re: two glass issues
But in complex projects it can be a huge pain for non professional modelers to archive perfectly cosed volumes for glazings like this:
So it is a great + if the render engine can deal with them as maxwell does. The same is true for flipped glass surfaces.
Often this kind of 3D models arrive from nurbs based softwares which have even bigger issues in creating perfectly closed surfaces.

Re: two glass issues
now i get this with identical scene and geometry, only camera angle varies

Re: two glass issues
this seems an issue of large glass surfaces with small thickness
Re: two glass issues
Is there a tolerance value which has to be lowered in order to get this kind of glass volume right?
Re: two glass issues
What app do you use?
At what scale, size & units is your object rendered?
Your "bug.obj" geo, though relatively big (~20m high) renders fine with BlenLuxCore...

Re: two glass issues
interesting... are you using bidirectional? I think scale is meters, however it should be clear looking at the scene files i attached.
Yes, i revised it is in meters.
