Nice idea, and some presets look very good. In the default one, however, sand looks a bit unnatural.

Yup, looks promising.

One crit: The sand is supposed to have washed over the pebbles, but the height information of the bump map reveals that the pebbles have actually been corroded away in those areas. This should be corrected IMO.

Thank you, guys! smile:)

Haven´t posted in a while now, so I decided to drop in.

Vladimir, more like this?

The one on the left is the one submitted, on the right I made a few changes.

Dilla, I´m not exactly sure, but do you mean something like make the top sand layer lighter than the sand beneath the rocks?

Take a look at the greyscale values of the sand. They are essentially uniform across the entire bump map, meaning all the sand is on one and the same 'height' level.

However, at any place where the sand has washed on top of the pebbles, we should see the correct height information for pebbles plus a very slight height alteration due to the tiny sand particles that cover them. Try blending a medium to high roughness noise over the pebbles heightmap (masked of course), at very small blend values (say 0,05) with a blend mode of screen, overlay or lighten...

yep, I thought that was what you meant.

Here is the modified bump map that comes with the right side of the image above.

I blended the top layer on itself in screen mode.

Yup, that's what I meant, but take care that the pebbles remain smooth in those areas that have no sand over them by masking the blend. Also, the height difference between a pebble with sand on top vs. the same pebble without sand on top should be very very minimal, just a slight change in roughness on the normal map, basically. smile;)

Changed the blend from 100 to 30%, and yes it is masked. Update sent.

Thank you so much for the help, Dilla! smile:)

The one on the right is much better! Add that to Dilla's suggestion and you got yourself a real pebble beach! smile:)

Thank you, Indigo! smile:)

The example on the right has now replaced the previous version sent.

This is really nice. smile:)

I like how it appears to have shadows and a kind-of wind swept look. I will use this one.

You have a lot on very nice filters. I only noticed them today. smile:blush:
