I have simple sphere and added some hair particles. I want to export it to obj file and i have converted the hair particles in modifier tab. And exported but i did not get the hair particles just normal sphere. How can i convert the hair particles.
When you convert hair particles you get vertices connected by edges. Most programs will only draw faces so you won't see the hair outside of blender unless you create some geometry that can be drawn.
- Convert the hair particles to mesh.
- Convert the hair particle mesh to a curve. ⎇ AltC-> Curve from Mesh/Text
- Add a bevel to the curve - effectively turn each strand into a tube. For the fill option, front and back will give a quarter tube, half a half tube and full will fully enclose it. The depth setting determines how big the tube is while the resolution will subdivide the tube to give a more rounded result, a resolution of zero will give a four sided tube with fill set to full. You can use the extrude value to give them an oval shape. Note that extra resolution increases the geometry to export but would provide little variation to the visual result of the small hair mesh.
- Convert to mesh. ⎇ AltC->Mesh from Curve.
Select the object, then go to Object Modifers and click
Convert in the Particle System menu.
This gives an extra mesh separate from the object, so you can remove the particle system from the object and join the objects together by selecting the hair and the object together (ensure object is active) and pressing Ctrl+J.
To give hair faces, set pivot point to 3D Cursor, and place the cursor in the center of the sphere and hair (if sphere and hair are in center, then just use
Cursor to Center with Shift+S.)
Then enter edit mode on the hairs, and select all. Press E to extrude, then RMB. Then press R then Z to rotate on the Z Axis. Move the mouse to give thickness, then LMB to confirm.
