floor material vray


Recommended Posts

Hello guys.

First of all, i would like to thanks to this comunity for beeing so helpful. Every time i have doubts about a specific problem, i google it, and almost always end up here, where my problems are solved.

I´ve been around here for some time, but this is my first post, since i can´t find the right answer. So here it goes.

I´ve noticed that on a ceramic tiled floor, the reflections have some kind of break between the diferent tiles. I´ve been wondering how i could achieve this effect with vray materials.

Sorry if the english is not correct. i atached an image for a better understanding of what i´m refering to.

Thanks in advance to all of you.


p.s - Fro my understanding, this happens because the base flloor isn´t planar, it has minimal different heights, and that´s what causes the irregular reflections, but how to translate that to the material without having to change the mesh.

As above is the right way to go but something must not be working.


You could use a tile map and change the color variance parameter which will give each tile a slightly different grey value. You could even plug in a gradient into the tile slot to give each tile a little bit of tilt.

Ok, thanks. That´s exactly the aproach i took.

I used the colour variance of a tile, mixed with other tiles in order to have a different shade on the different parts. I also used a gradient ramp to have a smooth bump in the outer parts. But it didn´t work.

So, i must have missed something. Now that I´m sure this is the right way, i will no lounger waste my time trying different techniques, and i will concentrate on this one.

Hi, WAcky.

I found the Problem. I didn´t had enough diference in the tiles. As soon as i increased it, the effect started to show up.

But what made a huge difference was your advice on the gradient, wich made the final effect more convincing.

For the gradient i used a composite material. First layer a checkered tile with a soft gradient. Then i used a second layer with the gradient in an opposite direction. Finally the last layer has only the division between the tiles wich is the stronger bump.

I´m wondering if it wasn´t better to build this map in photoshop, and use only one bitmap for the effect.

One side proceduals, on the other side a bitmap.

One more time, thanks for your help and precious advices.

I had the same problem. I had the tile subdivided by 4x4. I was trying to have different variation along the tiles, but i had a hard time. So i swicthed the tile for 2x2, and this way i could have more control over the maps.

But, i think that Wacky solve our problem with the bercon maps.

The way i did it, in order to have more variation i had to use more maps, and a lot more time consuming.

Thanks to wacky again.
