Thnx… I thought it was good for beginners who at first are maybe a bit stubborn, but then getting the evidence right in the face .
I still went a different root with creating stones, which gave me the control I wanted. Just starting from either a cube (subdividing in several times), a UV-sphere or icosphere, go into sculpt mode and using a few “brushes” to bloat or flatten. After that, decimate if started with to more faces you where aiming for.(and noticed that it is sometimes better to not decimate too hard, apply it and throw in another decimate-modifier). That way, I had 8 rock in 15 minutes I liked more and had better control over, with only quads and tri’s.
So spending a few days to create rocks and cliffs, but learned a lot by it.
Speaking of cliffs. Because the tutorial I followed and the scale of the cliff I needed, that cliff-mesh ended up being over 200.000 faces for one portion of the cliff. And currently I have 5 of these planes to make up the cliff. So I decimated it 'till I got around 11.000 faces per section. But the “rocks” in the cliff ended up looking a lot softer then the rocks I’m spreading manually.
So for the cliffs, I went for your solution regarding particles-system to distribute the rocks (on a plane). Don’t know the poly-count yet, but it’s a lot crispier that way and since I got around 300 faces/rock, probably a lot less faces. With being on a plane, I can create the shape of my cliff that way. Don’t yet know about performance though and still figuring out a bit of the controls of the particle-system.
Here comparison of the 2 cliffs:
Thanks, these conversations are very helpful in pointing me in good directions
