beach sand texture

ibic

hi all,
first of all i would like to thank all forum members who have made tutorials and share their knowledge.i have some experience with 3d (archviz).currently i am trying to make a beach sand texture, to learn DTE.i am attaching reference and my texture,bryce file
https://www.dropbox.com/s/ynwyngoqh5mp0x4/beachsand.zip?dl=0

i am using single channel mat -within one tex for sand grain bump(rand continuous) and voronoi for the miniature dunes and mixing by Average,how to i reduce proportion of sand grain bump (now i use clip filter to reduce contrast) .also,i would like to add a dusty effect where light hits( velvet like falloff?).i have not yet played with material prop.(spec etc).any comments for improving it are welcome.

Hi Ibic welcome to the forum.

I don't know much about the DTE and someone will reply to your message soon. In the meantime have a look at David's beach material in the Pro Materials- Terrain - Beach, maybe you will get some ideas.

That looks pretty good.

You could use a sin filter to soften the grit rather than smooth clip which can be a bit harsh in the way it deals with bump.

Velvet falloff would be nice, but that is not an inherent feature of the Bryce materials. It is possible to simulate a velvet effect through bump but it would be nearly impossible to get it to work nicely with the existing bump that way Bryce Made Easy - Velvet bump recipe - by David Brinnen

Here a sandy effect I made in a single channel. Looking at how that was done might help?
