Hey guys,
I would like to have a tree bark with moss/mold then have very realistic snow on the moss/mold.. making it seem to have three layers.i.e tree bark,moss, snow

I initially attempted to have the moss grow on the tree bark using corona hair material then tried to layer the snow on the moss using a layered material but my little experience in texturing proved poor results.

P.s The image is required to be upclose hence need more detail. i could have used Ludvik Koutny's very nice snow material or one from the material library but a closeup render did not yield the high details i was looking for.

Kindly advice on how to approach the issue

Hi there, I used 2 surface here, one for the rock and the scatter and the other for the snow/displacement. Unfortunately, it's not possible to scatter on scatters at this time. I hope this helps. Excuse the rough render ;)

Thank you bengamin for that quick response..
but it seems that my idea of having snow on the mold may not yield directly from the renderer..i was intending for the moss to grow on certain areas of the tree bark,then scatter snow on the moss but if its not possible to scatter on another scatter, i may have to consider photoshop as a final option

Having an image to go by would be great. The example Benjamin created looks great for what it is. Curious if you're saying you want the snow to look piled up on the little leaves of the moss or just splotches of snow? Using stacked materials with clever masking to limit where the snow should be sounds possible, but no knowing how it should look....

Also, for what it's worth, Mograph Cloners can clone onto other Cloners.

Another option would be to make the scatter editable and then scatter once again on that. You could use the terrain shader to mask off the snow. Or BigAl3D's suggestion of using MoGraph cloners. Or this :)

Hi, here's a quick example of scattering on a scattered objects after being made editable. You could probably use metaballs to join the clumps of snow. I haven't tried that though ;)

Yes bigAI, I intended to have the snow on the leaves..i havent seen an image which i could provide as a reference but Benjamin's pic is similar to what i had in mind.

I will attempt to making the scatter object editable or use the cloner on cloner method. I tried using a layered material(not sure if this is the same as material stacking) since the tree bark came with the textures separate.

I will try to photoshop or create a sketch to show you guys what i intended to get. but first ill try out Benjamins and BigAIs suggetstions.

I also tried that snow plugin i.e csnow but it was too metaball-ish and adjusting the parameters didnt yield much of what i hoped for

Hey team,its been a while but my attempt to make the snow had some challenges. I tried both the snow texture as well as modelling the individual particles but both didnt turn out the way i hoped. 1. The texture didnt produce the realism and detail i hoped. 2. I modelled 5 individual snow particles and used both chaos scatter and surfacespread to distribute the particles but the number of clones proved overwhelming for my machine. I tried 2000000 clones on both plugins but it did not manage to cover the entire area. Anything more than that was taxing on my machine. Im running on an xeon dual processer with 2.8ghz 48 cores. Kindly help, not sure what im doing wrong.

Attached is an example of what i want to achieve(Left) as well as the failed attempt(Right) I also tried.

Just to clarify, the first image does not have mold but would want that detail on the mold itself rather than the whole obj.

For the frosty branch, have you tried a simple fresnel shader over the bark? :)
