Ok, yep, I’m new at this. But I have been trying very hard.
I am trying to use blender to model things for cnc cutting. Primarily wood carving.
I am using Inkscape to create vectors around an image that I plane to use as a displacement map. It’s a bird. And I’m trying to capture some of the texture of the feathers.
So, I have my greyscale image. I set up my Inkscape image size. I added the image to the file. I traced the image with Bezier curves to make a path around the image. I deleted the image from the file and saved the path as a standard .svg file.
Open blender, import svg file, fill, make a mesh from the curve, kept a copy of the curve, extruded the face about an inch, turned on 3D printing tab, set Degenerate to 0.00001, set overhang to 90, checked all, Make Manifold, and vwalla’ I have a manifold object that should be 3D printable and cnc cutable.
This is where the problem starts. http://stevemarti.com/from-2d-to-3d-turning-images-into-objects/ is a short tutorial on making 3D object from displacement maps. I can do what he diescribes, BUT, my finished object is just a plane and not an object with thickness a flat bottom and the desired texture on the top surface. It seems that what is happening is only the intersecting areas of the plane and my 3D object are making it through the modifier. I understand that. But Steve shows a different outcome, a flat bottom and some mass beneath the textured surface.
So, Blender Guru also talks about creating a displacement map when creating textures.
Here is my issue, after making my manifold 3D bird with just flat top and bottom faces I want to subdivide the top face so that I can use a displacement map to add a texture to the top face. In edit mode I select the top face in face select mode. I hit subdivide in the tools tab and I end up with only one face. To be precise when select the top face Blender says "Verts:636/1,272 | Edges: 636/1,908 | Faces:1/638 | Tris: 2,540 | Mem: 11.9 MB | Curve001. It’s not a curve it is a mesh. It’s just named Curve001.
After Subdivide Blender says."Verts: 1,272/1,908 | Edges: 1,272/2,544 | Faces: 1/638 | Tris: 3,812 ect…
So, my faces did not subdivide. But my verts doubled as well as my edges. I do not know what Tris is yet.
Is there a step I am missing that will allow me to subdivide the top face of my object?
Thx in advance!
