Shadows through "HighGradeGlass"

[ktejlgaard 10]

Hi Ive spend hours trying to figure out why I cant see shadows cast from "HighGradeGlass" properly when looking through "HighGradeGlass" (see image)
The shadows cast from the glass get all black when wieved through the glass. I can get around it by using AGS but Im loosing detail on the shadows and reflections by doing so.
How can i get proper shadows when looking through the glass?

High Grade glass objects need to be solids modeled to the correct thickness, just like glass in the real world. (i.e, not a surface as you would use for AGS.) Is your model set up this way?

[ktejlgaard 10]

Each sheet in the dome is modelled as a solid with a thickness of 6mm. (like the real thing)
I tryed the same render with simple blocks, and got the same problem

Please post a simple example project, so we can further advise you.

Do you want a FMZ or MXI file?
attached a render of the panes/blocks

formZ project file

GlassTest.zipI have attached a Form Z file with three blocks and the "glass texture"

And thank you so much for the quick reply!

Hi,

 

In Maxwell Object Attributes, enable the Hide From -> Global Illumination on the glass objects. Does this help?

 

(If not, please export your scene and send your MXS and MXM to Next Limit support; perhaps they will have an alternate solution for you. https://portal.nextlimit.com/ )

Hi,
Hiding from GI is part of the "work-around" and then having an additional object with AGS that is hidden to the camera, casting the shadows.
But it seems wrong that I cant use the proper shadows cast from "HighGradeGlass" because they cant be seen through the glass itself?

I agree. Please contact NL support (see link above) and provide your MXS and MXM as examples. This is not a formZ-plugin specific issue, so don't include your formZ project, or they will kick it back to me.

Hello,

Adjust the transparency setting in your MXM to a higher number and a greater amount of light will pass through your glass (and then, in effect, the glass will not cast a shadow). If you enter a transparency value greater than the size of your object, I believe 100% of the light will pass through it.
