Help with washed out wall finishes

[bmcgonigle]

Good Day,

 

I'm working on an interior space that has wall wash lights highlighting accent walls that are painted with corporate colors. I'm struggling with the colors being washed out by the lights and not matching what the corporate colors should be once the rendering is complete.

 

I'm working in 3ds max 2009 and MR; the material is a basic A&D material with the corporate color set in RGB with a matte finish. Not sure what other details one might need to help.

 

So far I've tried the following:

 

Darkened color - still washed out too much

Excluded wall from light - loss of light scallop, etc

Adjusted reflectance settings - still washed out

Scaled down rgb in material settings - still washed out

 

Any suggestions would be greatly appreciated on this.

can you post an image with the paint swatch overlaid on top for reference?

Are you using Gamma correction?

 

Is it only the walls being washed out?

How did you reference the colors? and create the material (scanned a swatch, known RGB etc..).

 

If you get a chance post up an image with a bit more info.

Can't post an image due to client confidentiality but I did find a work around by creating a bitmap based on the rgb values and reducing the RGB output until the paint rendered correct. The whole image wasn't washing out, it was just that paint finish. I also did some post gamma processing that helped with the contrast. A bit more tweaking in pshop and I should be good to go. Thanks for the replies. Cheers!

I'm not a Mental Ray user but I experience similar problems with VRay from time to time. I've found that a decent workaround is to make a blend material (in my case a VRay blend material) with the standard (VRay or Mental Ray) material as the base and a self illuminated version of the same material as a coat material. In most cases I adjust the gamma of the self illuminated material, whether it be a bitmap or solid color, with a color correct map where I tweak the gamma settings until the desired result is achieved. You can play around with the blend amount to get the right balance of light affecting your wall surface.
