I would like to create a large natural landscape with animations(waterfall, river, ocean, wind moving objects). I am a just wondering if the polygon count of a epic landscape is feasible in blender. I dont know how a plane or ANT terrain object subdivided many times for detail would behave in the scene window or even if the entire object would need high subdivision but I do know I would need high subdivision at many points on the objects since I would be sculpting detailed cliffs and mountains(not simple smooth falloffs created with proportional editing) and I also know a cube I created with 100,000 verts rotated ok in the Scene window(Wireframe) but the next subdiv(400,000 verts) barely moved.

    $\begingroup$ 1st get an epic CPU, then get a few epic GPUs, add an epic amount of ram. Maybe even sign up for an epic render farm.... Besides that, there are epic shortcuts to optimize scenes... It all depends on what you define as epic... and how epically realistic you want to get... $\endgroup$ – cegaton Oct 26 '16 at 4:33
  • $\begingroup$ ok let me simplify the question. Can blender really work with a high polycount on lowend machines? On Zbrush I can go upto 2million polys. On blender it seems I cant go past 100,000. Or rather 100,00 works but 400,000 doesnt. $\endgroup$ – Anoop Alex Oct 26 '16 at 5:23
  • $\begingroup$ It's not the best comparison. ZBrush is not 3D application, it's 2,5D meaning that it edits like 3D mesh only current one while it's in Edit mode. Once you exit from there the object will become uneditable 2D representation of itself. Hence ZBrush can operate really high polycounts by lowering amount of resources on other things. Blender is 3D app which allows editing of all objects in the scene and does have ways to reduce resources usage although they aren't endless. $\endgroup$ – Mr Zak Mar 9 '17 at 16:08

To operate with high polycounts you should make sure that your scene preview subsurface levels are as low as possible when you aren't working on them(so split up your scene into smaller sections). Also, you can put sections you aren't working on in wireframe view(this does help). Splitting stuff up into different scenes also helps.

When I do high polycount scenes I work on them section by section on different layers then put them all together but only leave the center in solid mode.

So yes, Blender can work with high polycounts on a lower machine but you'll probably have to jump through some hoops to do it.
