Background image without affecting light

[Anonymous]

I want to add a background image without affecting the lighting of the scene. Each time I add one the lights changes. I'm using Art renderer but I guess could happen in other cases.

Is there any way to add a background image to the render without affecting the render lighting?

I know this can be done in postproduction using alpha but I want real time feedback.

try to UNcheck the GI from the map itself . usually , all renderers process the background and env maps .

open it in the material editor , and seek the GI option of it , unchek the GI . in this case , the render engine you use will ignore it from the global and final gather illumination .

I can not find any GI option in the bitmap map options. It is simply the one included in MAX as ART has no other available. The physical Material has no options either.

Yes, I have the same feeling as you, it's really painfull to work without the background image with Art render that adds the new physical Sky as a background. There is no option to keep the sky used but seeing a background photo. It seems the background just can be a HDR Image...That's really unbelievable to not be able to use a simple image as a background in order to work on the light intensity and materials colors according to this background image as a reference... Every render engine makes this available as a standard, why not here in art render...? strange indeed... or I missed the option...

I had same problem, here's what I found..

"In 3ds Max, the "GI" option for controlling Global Illumination is not directly within the material itself, but rather found in the render settings under the "GI" tab, usually accessed through the Render Setup window; you'll need to be using a rendering engine like V-Ray to access the specific GI settings within the material editor depending on your chosen renderer. "  I have some images of me finding what they were talking about but it didn't work for me, I guess because im not using vray.. sorry
