procedural marble

[Chad Warner]

I've got a HUGE marble wall that I need to work on that has the attached pattern on it. The grain pattern is very pronounced and I don't think tiling the image is going to work very well, even after pshop cleanup. I've looked to see if I could find any texture generators that would do marble very well, and I was wondering if anyone knows of anything that would work well.

 

Thanks,

 

Chad

Can you get one larger image and then, instead of outright tiling, make a few versions that are crops that change progressively and then book match them?

[Chad Warner]

That was how I dealt with it in the past, but the problem this time is that the largest piece I can get a picture of is a 12"x12" tile, and the tile in the rendering is 42" x 72", tiled over a wall that is 150' long and 50' tall.

Have you considered visiting a contractor in your area that installs stone into homes/commercial places? They usually have solid slabs of stone that are 8'x12'. Your project will certainly have seams in it. They may even have several slabs from a single block. It might cost you a few dollars for the yard hand to shuffle the blocks for you, they may even want some photos for their sales department.

I had not thought of that. I'll look into it and see if I can come up with anything.

You can try Darktree, it is pretty nice.

 

www.darksim.com

 

you can install the simbiont as a plugin for free without buying darktree which will allow you to render out darktree textures.

Then you can grab some of the stone shaders that you can just get for free (the green or red marble will be your best bet below), then slap a color correct on it to pull out the saturation.

And..if you like it you can buy Darktree for tweaking the textures, and making your own, it is pretty sweet.

I actually tried the green marble shader, and while it worked quite well, it still wasn't getting me the results I was looking for. My client is being VERY picky about it, and I'm still having issues getting the effect they are looking for. So I'll keep working at it.

hi chad, i am facing a similar problem right now, but with a limestone that has a slight marbling grain to it. i did a quick search, and found this tutorial for creating marble in photoshop. i am going to try and adopt it to what i need, and create a large texture map that does not tile. maybe it will help you.

....so, you can probably select individual random squares out of this tile, and re-arrange them into a non-tiling marble tile pattern.

Certainly worth a shot! Thanks.

 

I actually found another similar tutorial here:

but the methods were slightly different.

i think the twirl filter in that one really helps set it off. one of the problems with the tutorial i had was that the pattern still felt a little random, but i think if you were viewing it at a distance, it would not matter as much.
