Are these IRay shaders, and what are your favorite stone shaders?

Quasar

Since it doesn't say from what I can tell, are these stone shaders set up for IRay?

Also, what are some of the best IRay stone shaders for rocks in the store?

Yes, they are Iray shaders. I haven't had a chance used them yet. But there are two shader products I like for stone: Martin J Frost's Rock and Roll Stone Shaders (Rendo) and JGreenlee's Ingenious Rock Shaders  ( https://www.daz3d.com/ingenious-rock-shaders ). I also use a lot of ShaaraMuse's Rock Textures and LOVE Andrey's Stones sets ( https://www.daz3d.com/stones-hr , https://www.daz3d.com/stones-hr-2 )

Thanks for the leads. If you get a chance to use the shaders I linked, I'd be interested to hear what you think of them. For now, I'll check out the products you mentioned.

If it doesn't say definitely anywhere else, check the What's Included section for exactly which types of texture maps are included. In this case, Base Color and Roughness are the names of surface parameters you only get in Iray (Normal and Bump have the same names in 3Delight).

Nice tip. Thanks. 

Lucky me, the Ingenious Rock Shaders are .99 .79 today.

I've also been using Ingenious Rock Shaders. However, I did recently got the Rough Stone Shader. So I ran a quick test to compare similar textures from both sets. I've got to say the Rough Stone Shaders results were fantastic and it's hi-res textures were used in its creation.

First Angel (left) is using Ingenious Rock Shaders, while the second angel (right) uses the Rough Stone Shaders. By the way these are out of the box, so I left the tiling at 1 x 1.
