Reflective tint on other objects

[Ayman Ali]

Hello everyone! I am newbie in visualization, I wanted to ask how to prevent one object from reflective tint/light of another object. In my case for example, white walls get yellowish tint of the floor material.

What render engine are you using? What your describing is a realistic effect, you may be able to bring it in to acceptable levels by changing your material properties before you go down the brute force method of stopping it completely.

Use an override material. Pipe your floor material into the base/default material slot and then pipe a basic 50% gray material into the GI slot. This will work for both Vray and Corona.

@Tom BusseyI am using Vray. Does Brute Force prevents such reflections? How does that work?

I think Tom meant to adjust your floor material first, and if this doesn't helps then use some overwrite material as Corey mentioned. His brute force reference mean to forcing something rather than using 'Brute force' Global Illumination method.

If you are new to Arch Viz rendering, one of the things you should know is that never use extreme values in colors or materials. this mean if you have a yellow floor never use the maximum hue on that color, usually staying under 80% of color intensity is OK. There are specific tables with 'Albedo' values for each material.

The same applies for Black or White color, there is nothing that is 100% White or Black.

Usually if you keep the color intensity within this range, the color spills or color bleed (the actual name of that effect) will be natural. If your client stills doesn't like it then you can use a material overwrite in the material spilling the color.

Specific information can be found inside V Ray help docs how this process works.
