Sunlight shadows not showing up in interior view

[Tupi22]

I'm a fairly new user to Home Designer Pro, so sorry if this is a dumb question.  I'm having trouble with shadows inside the house.  The first attached picture is Chief's tutorial which shows how sunlight can supposedly cast shadows inside the home.  The second picture is my house model showing the outside of the house, just outside a bedroom, where the sun shadow is properly cast. But the third picture is inside that same bedroom, and there is no shadow.  Am I doing something wrong?  If it helps, I don't have any interior lighting set up.

Try opening camera view light settings, adjust sunlight use generic sun, set intensity to 100000 and adjust sun tilt and angle.

It has no effect on the interior, there are no shadows at all.  I get shadows with the lights on:

 

 

But as soon as I adjust the sunlight, all shadows go away:

 

 

The outside part of the house does get shadows as expected:

 

 

I wonder if it's some kind of a technical glitch rather than something I'm doing (or not doing)?

Each camera has it's own display options. Try turning shadows on for the camera you are using for the interior view

Thank you, bit I believe the shadows have been set to on:

In that view, go to the top toolbar and look for the "house" icon next to the mouse orbit tool. There you can toggle shadows on and off too.

It only works on the outside.  Here is the outside with shadows toggled on and off (look at the shadows near the grill):

 

     

 

But on this inside, it only changes the shadows from the ceiling lamp:

Either try to post your plan, or take a look through the reference manual. With just images, it's impossible to see what your settings are that may be doing this.

I'm getting an error trying to upload the actual plan (it's 13MB, so below the 14MB max size).

 

But I did open a new plan, and copied and pasted the original plan into it, and lo and behold, the interior shadows work!  I didn't change any default settings, so this is a mystery to me, but I guess I'll just trudge on and not ask "why".

In case anyone comes across this issue in the future, I figured out the problem.  All of my glass defaults (windows, doors, skylights) were set to Glass Grey in the Transparent Glass materials options.  For some reason grey glass does not transmit sunlight in my model (even though it says Transparent).  Once I switched the glass to Glass Standard, I got the result I wanted.  Very strange.

 

Here's an example with the glass door having grey glass, and everything else being standard.
