Exterior rendering - issue with colours
show user profile  auggie
I'm doing exterior renderings and having a horrible time trying to get the colours to look like the paint sample. For instance the gray sample comes out looking too yellow.

Here is the colour sample & rendering:

I am using 3dsmax 8, MR, daylight system with IES Sun & IES Sky.

Any help would be appreciated. Thanks.

*Edit - cannot figure out how to add images either

This is caused from the color of the sun affecting the scene. In vray, you can counter this by adjusting the white point in the camera - Im not sure what the alternative would be in mental ray. If your worried about your swatch colors then I would be inclined to render a matte of all your important surfaces at when you are finished, and adjust the color to match exactly in photoshop. Your GI will always tint the colors a little anyway so if its that important, adjust it later.

edit: Alternatively, could you just place a direct light where the sun light is and use that instead and set the color to white? By default to emulate the vray sun I would set the direct light intensity to 2 (might be same for mr sun you will have to check)

Thanks for the suggestions. I will try using a directional light instead of the sun, and investigate changing the white point in the camera. I don't really understand what you mean with the Photoshop alternative though. Could you give me a quick overview of that process, at least the bit about render a matte of the surfaces? I actually don't have Photoshop but a colleague in the other office does.

Thanks.
