Hi, 

I have a project where by i need some glass panels to cast a shadow. 

The glass is intended as PV glass and slightly opaque, with a yellow or dark colour tinge to them. I need the glass itself to cast a shadow behind the glass. 

Is there anyway to do this? 

I have tried using an image as a material in the hopes that it would cast a shadow (as a solid element) however this does not work.

I have attached an image to provide some context to my question. The frame work casts a shadow, however not the glass itself.


Regards, 

H

Do you mean it casts shadows in ProWalker (not Podium Walker).
I wonder if you turned on Translucent Material in the Options/ Env area that you would get shadows.  If the color in the glass is from SketchUp, (and not imported), at least you should get a colored shadow.
If you import an image, podium will ignore it since it's not mapped to a face.
So, you might add a little bit of SketchUp color to the glass.

It depends on how the glass is configured. The more transparent it is, the less pf a shadow you will get.

Bear in mind that this is how it will behave in reality.

Hi, 

I realise its just finding the balance between the level of transparency required and the amount of shadow i need. 


I can get it to cast a shadow, but i reckon i'll take the image to Photoshop to increase the darkness of the shadow. 

The glass is part of a PV panelling system which is angled at 12.5degrees to aim towards a gap inbetween some tall buildings (maximise sunlight) - the idea is for it to show different shadows throughout the day. Its a major design feature for this project, and it took a while to figure out.

Thanks for your assistance. And yes, ProWalker, got carried away with Podium in my head.
