Tree trunks?

[N-drju]

I wonder how to make fallen tree trunks. Like the ones overturned by the wind or erosion.

My first thought was to use some relatively "branchless" XFrog species, remove all leaves and flowers by setting opacity to 0 and simply putting the remaining parts on the ground. The thing is, that there are not many tress that have no branches... (old, mossy trunks rarely have any) so I'm looking for a different idea perhaps? Maybe some heavily tweaked primitives?

I'd say, if you can afford it: nothing beats Quixel Megascans.
Otherwise, it would be best to edit the tree models in a 3d app and delete all unnecessary parts.
If you have a tree with branches that have separate materials, you can play with the opacity in TG, but there may be holes in the mesh.

Hehe, I forgot that I have an old XFrog buried on my old computer. With its use, I think it should be pretty easy to turn some of the existing trees into dead logs. I don't really understand how texturing in XFrog works, but that should be cheaper than Quixel. Later on, I can perhaps make some local changes to the coloration of bark etc. to make it look decomposed / mossy / aged.

well that should work, I doubt they've upgraded the modeller since forever

If you have any familiarity with Blender you might try the sculpting tools.  It can turn out some pretty decent stuff.

I still keep an eye on Daz 3D since my Bryce days, and they have some pretty good stuff if you ignore what my friends in Salt Lake City call their orc porn. There's some deadwood that might need your needs at

Usually you can find obj files if you drill down far enough. Failing that, their free software Daz Studio lets you export to obj.
