To put the STEPper add-on to the test, I paid a visit to the extensive GrabCAD online model database, and downloaded an Aston Martin look-alike car, created by Keith Moore. The new version is available at a very reasonable price, supporting Tommi to keep perfecting it. But following feedback from Blender Artists forum members, Tommi introduced a much improved new version of the add-on, rewritten from scratch. The first version of the STEPper add-on was released for free, and it is still available for free. Create a new Substance Painter project by clicking File > New. Import and prepare the FBX file in Substance Painter. Make sure that you use the following export settings: Click Export FBX. Ambi) has released a Blender add-on called STEPper that allows you to import the popular STEP NURBS format (often shortened to STP) straight into Blender. Enter the path to where you want to export the file.
So there are some hurdles along the way from CAD to Blender, especially if you do not own NURBS-based CAD software.īut the Finnish developer Tommi Hyppänen (a.k.a.
When you've exported a polygonal format like OBJ from a NURBS editor, you'll have to see if the normals are properly exported and then correctly imported into Blender. The best NURBS to polygon mesher I personally know is the export module in MoI 3D. Not all NURBS editors have a neat meshing algorithm. Previously, if you wanted to import a NURBS model into Blender, you needed to convert and export it to a polygonal format from a NURBS editor.
