AC18 - shadows not showing up in "OpenGL" mode?

rob2218 — Thu, 11 May 2023 13:08:57 GMT

I have the "shadows" ON in my 3dwindow settings...yet the "shadows" don't show up as I view the model in 3D?
any suggestions?

...and you're sure that the 3D Engine in the 3D Window Settings dialog does indeed say "OpenGL" (and "Shading" for the mode)? No other mode combination will show shadows...

Also: shadows do not display during navigation. Only when you stop moving.

yup those are the settings I have....and when the model is standing still (no navigation) I still can't see shadows....? dunno.

Check your 'Sun Altitude' in the 3D Projection settings.
Is it 90° (i.e. directly overhead) by any chance?

I doubt it, or there would be a shadow from the overhang above the garage door.

A graphics card issue perhaps? You have Windows and Mac systems listed in your signature, Rob. Does it occur in both?

I didn't look at the model image that closely.

How about in the 3D Projection settings > More Sun.
You can set the sun to 0% and that will turn the shadows off.
If ambient light is set at 100% you will still have a brightly lit model - just no sun and shadows.

I figured it would be the sunlight's contribution to ambient. Either way I bet one of them fixes it.

leaning more towards the "graphic card" inadequacy.
Here's why. when I turned off the site "mesh" the shadows showed up. I was able to rotate around the model, and soon as I was done orbiting, the shadows appeared. Then I turned on the site mesh....and shadows don't show anymore.
it's a very strange peculiar behavior but it appears to be that the graphics card simply can not keep up.

OH and by the way...the sun angle was at 45 degrees to the horizon, and not 100 intensity......so that was not it.
Also, it's on a PC where this issue is occurring. The architect I'm assisting is using a "TRIAL VERSION" of the software but I doubt that has anything to do with anything cause I'm told the trial version "IS" the full blown version, just with a timer.....so....I'll investigate more next week.
