    Angry Problem with intensity of black color

    Hi guys,

    title speeks for itself. When Im in Material browser I choose black colored material, like Acetal Resin and in a appearance tab i see its quite a black, but when I render it, its gray... Even when i tint it entirely black 0 0 0, its the same... Thanks

    There are no true blacks in real life... well there almost is but it's a brand new material scientists made. Every black looks grey to some degree depending on how much, and what color light hits it. In a rendering you'll need to work on your light and render settings to get closer. If you're not doing a rendering but instead using a visual style then choosing Consistent Colors will do what you're looking for.

    The roughness of the material, how much it scatters light vs reflects it, also plays a significant role. Now that I think of it, probably more so than the light striking the surface.

    I was just describing this to a colleague yesterday as my black materials were apparently coming out grey when rendered but on closer inspection it was the high gloss on the black paintwork that was reflecting the horizon that made it appear grey.

    It is true though that when linking Revit fbx exports into 3dsMax for rendering the really dark greys always seem to render lighter and need remaking in 3dsMax - even when inputting the correct RGB etc values for the particular RAL colour.

    What is making your material black? Does it have an image (or pattern) applied? We've run into the problem with paints and basic materials, including black plastic. By adding an image of the rgb value the rendering improves.

    Have you considered the possibility that even with all your light sources, the space is designed (intentionally or not) to be dark*?

    I'm really liking the last three as it goes - you have exposure issues for sure, and reducing the reflective properties, and/or bump on your PB material will the "hot spots".


    *If you want/need to fake some "extra" light, throw a studio light (or two) into the middle of the space, away from elements and out of view from the camera.

    I second jmk's comment... Use an image with the color you want instead of picking the color in Revit... Most colors render much different when you just pick the material color in Revit (especially darker colors). A simple 1024x1024 JPEG filled solid with your color is all you need.
