material tiling issue

[herdy1212]

Hi all,

 

I'm having an issue with my floor tiles in my renders, in the attached render image you can see the tiles as coming across very bright and in the corresponding image is what the tile should look like, any tips on how I can change the render image to look like the real tile itself.

 

thanks

Try to adjust the gamma. And it depends on what kind of lights you are using.

I darken my floors in photoshop.. CAD has a habit of accumulating light at the floor sometimes. Usually it's because I set my lights so they don't have "fall off" to decrease rendering times, or the lights are simply too bright.

 

Sometimes it's just WAY too much light, so I decrease lighting levels, both, overall, and on specific fixtures. but as long as the floor doesn't bleach out, I just "do it in post" meaning I correct it with photoshop afterwards. I also avoid giving the flooring a built in ambience in the material.

 

Also, that tile sample looks a little dark, are you sure that's not what it looks like under "comparable" lighting? I used to have tiles that looked remarkably like the "lighter" version you posted.

 

Many times I've found that product images are taken under weird lighting conditions.. You have to remember that they are lit with a light already on the tile, so rendering lights onto them is a double whammy of light levels.

 

I try to subtly tint my lights to make ambient light and/or to indicate what type of light source.. Yellow tints for incandenscent, true white for halogen, somewhere in the middle for flourescent. If there's a large window nearby, I mix a dash of white-blue into the lighting to show the effect of a clear blue sky outside. If it's outside, it get's blue too.

 

In photography, a filter is used to remove some of the yellow, in outdoor photography a blue removal filter is needed to remove some blue. Our eyes do it automatically. I add the yellow and blue as a very subtle mix.

 

There is no "absolute" lighting neutral in maps, your original image seems like it might have been photographed outside.
