Revit 2018 Material Image and Appearance Not Matching

[Anonymous]

When uploading an image to a material, my material appearance is showing up lighter than the image itself.  Is there any reason this may be happening or any way to fix this?

Bump map is applied.  Actually, the bump is the same as the generic image, so they will basically inverse the entire image as you have found.  Bump maps are usually the inverse of the generic image and black and white.

I tried turning the Bump Map off, nothing changed, if not made it even lighter.

Turn down the brightness...

Know what...never mind....don't know why it is like that.  It's like it is getting the full sun or something as when I change the scene to a cube or wall the material looks correct. <shrug>

The preview picture (with different configurations: cube, sphere, etc...) is lit with a preset lighting so it appears to be different than the image.

You mean between the Texture Editor swatch and the Appearance Thumbnail? I think it is an optical illusion. White background vs. Black background.   

Here's the scientific explanation:  a brighter object or relatively brighter object with its darker surroundings exerts a stronger force on its surroundings and on our cortex which in turn produces a larger image in our brain.
