If you find you are unable to move a curve handle in all three axis, it is probably due to the curve type being set to 2D. When you create the curve expand the Simple Curve dialog in the lower left of the viewport, or press F9: From here choose 3D and then, if you want curved splines, choose Auto in the Output Curve Type. The defaults are 2D and Vector and they may not be what you want for your curves....
In recent years, there have been huge improvements in n-gon’s (non quad polygons). Specifically how well they render and games engines handle non triangular or quad polygons – in reality of course, all polygons are reduced to triangles for rendering. Three vertices being the lowest amount of points that are needed to create two dimensional forms. It seems now that the last place that require quad sub-D models is in deformed meshes, character animations and the like....
Blender Class naming conventions - Python API As of Blender 2.8 the API naming requirement is for the class name to match the following convention: UPPER_CASE_{TYPE}_mixed_case Where {TYPE} is two letters denoting the class type inherited: HT – Header MT – Menu OT – Operator PT – Panel UL – UI list The class identifier “bl_idname” mast match the class name. Valid class name and identifier examples: class ADDONNAME_OT_my_operator(bpy.types.Operator): bl_idname = 'ADDONNAME_OT_my_operator' ....
Backface culling in Blender is set in two places, for solid view and for material view: Solid View In Solid view, i.e. Matcap, Studio etc. it is set from the topbar dropdown as shown below: Material View In Material view, i.e. EEVEE is it set in the shader panel on the right, as shown below: Advantages Using backface culling allows the user to see through the backside of geometry. This is handy for looking at the bottom of objects, through a ground plane for example....
This is the basic structure of a Pie Menu in Blender using Python import bpy from bpy.types import Menu, Operator bl_info = { "name": "", "author": "", "version": (0, 0, 0, 1), "description": "", "blender": (2, 80, 0), "category": "3D view" } class VIEW3D_MT_PIE_template(Menu): # label is displayed at the center of the pie menu. bl_label = "Operations" bl_idname="mesh.mypie" def draw(self, context): layout = self.layout pie = layout.menu_pie() pie.operator("auto.smooth") def register(): bpy....
Over the last few weeks I have been busy in Blender using the Decalmachine add-on to create some decal textures from Blender. You can find all my assets over at Gumroad. For more information on the assets for Blender and Modo just visit the link above.
