need help with mosaic floor

[salf]

Ok, heres the thing, I have to create a floor texture, is a mosaic tiling, not any fancy design, no flowers or paintings and stuff, just horizontal bars, with different widths and colors (random), what i did was to make the texture in real size on Autocad, then fill in with solid color hatch the mosaic tiles, export to Photoshop, and in there i made the diffuse and bump maps (jpgs).

 

Only problem with this is that i have to cut down the size, the real size would be something around the 8000 px wide (even more), and about 18 MB, which i think is to much for a simple diffuse texture map, but when resizing, of course i will lose resolution.

 

Is there any tip to do this, besides what i did?, maybe with MAX's procedurals or something.

 

Heres the diffuse map i made on Acad and photoshop (resized to post it), and then is a render test of the scene.

 

The main issue, is that in close up shots, the white joints between the tiles are way to noticeable.

You could use a gradient ramp in the diffuse map. Set the interpolation of the gradient to solid. Then just add as many colors as you want to the gradient.

Try a layered shader. there are a few types in max and when I use them there is always a lot of trial and error. I think your floor would look better if the colors within the stripes had some variation so I would try to use the procedurals tile map because it has a random color setting, though I don't know how it would work with your stripes. Maybe the bump map is hurting you in this case, sometimes bump maps can blur your textures. Maybe try using your hatch tile as just a grout layer, probably in the transparency channel, keeping the floor smooth. Nice idea for your floor, looks fun.

Here is a zip file of what I was thinking. You would have to play around with the sizing to get your stripe repeat to line up with the tile repeat though. I put a random color on the repeat to make the tiles more random, like mosaic tiles.

The first .zip file did not have the repeat included. Here is same file with .jpg repeat included.

THanks a lot all.

 

Patrick, thanks for bothering, i opened your test this morning, and it was the same solution i found out yesterday, hehehe.

 

However, im finding a new problem with this, the max. amount i can "repeat" the STACK BOND on the TILE mapping is 100 x 100, which is giving me floor tiles of about 10 cm x 10 cm ( around 4" x 4"), and the tile size i need is around 1"

 

So, then i thought, what about if increase the U, V, mapping coords on the UVW MAP modifier of the floor, and set them lets say, 2,2, this means that it will double the tiling, decreasing the tile size to some or less what i need, but this gives me a new problem, it will repeat the patern (diffuse-random color bars).

 

So, in order to bypass this, i will have to create another bar map, with bigger and less bars, so when it repeats on the UVW MAP, it looks ok.

lemme see if it works.......

/me goes back to work.

Ok, i did the floor, im happy the way it looks, you can follow now the WIP and results in this thread:
