Shadows are missing on some walls until they are selected, then the shadow is visible. Probably a Bug.

Steve,

Have you tried updating the drivers to your GPU?

In your signature I notice you have Nvidia GPU, these are well supported by ArchiCAD and generally safe to update to the latest drivers.

[Steve Jepson]

That didn't change anything. But there were new drivers released yesterday.

hi! This is because the white is too white, you can try adjusting the "contribution to ambient" value on the "sulight settings" panel

Or you can check if the suface panel emission color is black

[Steve Jepson]

Yes. Thank you. The White was Whitewash*. Emissions Color was were toooo white. Making Emissions Color darker did the job, and it is a good way to kind of match up the shadow color with the shadows on the other textures. What worked best for me was to match the Emissions Color for all of the materials in scene. That was made easy by saving the Emissions Color of the other materails as a Custom Color.

The very white as it will go color causes other problems as well with Rendering speed using Maxwell, perhaps CineRender as well?

In any case, the shadows show up just fine in White Model 3D Style.
So not a Bug - just a common issue to be aware of. Thanks again for the solution.

You know all of this of course but I just thought I would add some specific instructions for those that it may help.
