I made a script that clears the scene if there was anything superfluous), and adds two types of trees. With each click of the script, the trees are positioned differently, as well as their height. Script and screen import bpy import random green_plane = bpy.data.materials.new(name= "Trava") green_plane.diffuse_color = [0, 0.45, 0, 1] green_tree = bpy.data.materials.new(name= "Listva") green_tree.diffuse_color = [0, 0.7, 0, 1] brown_tree = bpy.data.materials.new(name= "Stvol") brown_tree.diffuse_color = [0.2, 0.1, 0, 1] green_black = bpy.data.materials.new(name= "Elka") green_black.diffuse_color = [0, 0.2, 0, 1] def clean_scene(): bpy.ops.object.select_all(action='SELECT') bpy.ops.object.delete() def add_plane(): bpy.ops.mesh.primitive_plane_add() plane = bpy.context.active_object plane.scale.x = 20 plane.scale.y = 20 plane.data.materials.append(green_plane) def add_tree(): for i in range(10): x = random.randint(-19, 19) y = random.randint(-19, 19) height = random.randint(4, 6) bpy.ops.mesh.primitive_cylinder_add(radius = 0.5, location = (x,y, height / 2), depth = height) cyl = bpy.context.active_object cyl.data.materials.append(brown_tree) bpy.ops.mesh.primitive_uv_sphere_add(location = (x,y, height), radius = 3) uv = bpy.context.active_object uv.data.materials.append(green_tree) for i in range(10): x = random.randint(-19, 19) y = random.randint(-19, 19) height = random.randint(4, 6) bpy.ops.mesh.primitive_cylinder_add(radius = 0.5, location = (x,y, height / 2), depth = height) cyl = bpy.context.active_object cyl.data.materials.append(brown_tree) bpy.ops.mesh.primitive_cone_add(location = (x,y, height), depth = height,radius1= 2) cone = bpy.context.active_object
