little help with ground texture(dirt)

[Billabong]

I have to do a closeup up the baseball field I have been working on and I have been trying to get the dirt part to actually look right, with no luck. I have been using Niel Blevins tutorial on using mix maps to combine 3 dirt maps, but its just not looking right. Ive attached images of what my dirt texture looks like rendered and the bitmaps Im using and what I need to achieve.

 

 

 

I would really appreciate any tips or suggestions.

 

 

Thanks for any help

I gave a shot at using the electric bitmap texture from the Blurbeta pack in a vray displacement modifier. I think it looks a little better, but still missing that dusty look.

 

Any thoughts?

I think it needs variation over the area.

 

I'd try a really large noise map over the area in bump, reflection and one to influence the saturation of the diffuse.

Thanks Jan, Ill try and work on it

How are you mixing them, have you tried a procedural cloud effect as an opacity mask varied and used on 2 of the three textures to vary the mix? It looks like it, but they are all at 100% it seams, maybe fading the two overlay layers a bit?

Hey Russell. Thanks so much for chiming in man, I am really struggling with this.

 

Right now I have 3 different dirt maps in a composite in the diffuse channel. Im using a Blurbeta noise and a Blurbeta electric as the two masks. and a large scale noise in the bump channel, plus a vray displacement modifier set, set very low to try and break it up a little, but for some reason the other maps arnt really showing up.

 

I attached some images so show you.

 

Thanks again

I think having all your opacities at 100% is hurting you and that having a base at 100% and tweaking the other two to say 70% (play with them) might help it all fade into one another.

 

Bookins also did a random grass tutorial using multiple planes and opacity maps that might be applicable to this scenario as well:

I do composites and blends all the time and typically only one material if that is 100%, I try for subtle finese!

Thanks Russell. Ill check out that random grass tut and let you know how it goes. Thanks so much again
