3D Windows OPENGL default lighting

Anonymous — Fri, 26 May 2023 12:18:15 GMT

Goodmorning Archicadistas,
I've been wondering if there is a way to have an evenly lit from all sides model when using the OpenGL engine or maybe raise the brightness instead? I would like to avoid getting the (much) darker areas as shown in the attached screenshot.
Cheers

View > 3D View Options > 3D Projection Settings

Press the More Sun... button. That should show you the dialog below. Play with the settings. For a 'clean' OpenGL look, I've stuck to white sun and white ambient colours. The more ambient, the brighter the image, though it leads to over saturation, in my opinion.

Also check the sun altitude. For nice shadows set it to something between 45-55 degrees. Try matching the azimuth of sun to azimuth of camera, or something in 45 degree steps if you have a mostly orthogonal model.

Try this:
Go to 3d projections Settings (by right click, or View menu > 3D View options)
Then click on more sun, and make contribution to Ambient 100%, that helps a little, and also try making the sunlight 100% if needed.

PD: Read Erwin Post is more complete explanation. I wrote this at the same time He was writing.
