OBJ Import
Ornatrix App can import Wavefront OBJ (.obj) files as base geometry to grow hair on. OBJ is a simple, widely supported mesh format, so importing it is a quick way to bring a surface into the App.
Importing geometry
Import an OBJ mesh to use as the surface a groom grows on. When the file contains several named objects or groups, a dialog lets you choose which ones to bring in. Each imported object appears in the scene and is used like any other base surface - for example as the input to Guides from Mesh Operator. See Importing and Exporting Geometry.
OBJ files contain meshes only, so the geometry is baked into the groom on import. Vertex positions, polygons, normals and texture coordinates are read; an OBJ file carries no hair and no animation.
When the file names a material library (mtllib) the material each object uses is imported with it: its color, roughness, metalness, opacity and emission become a Surface Material assigned to the object, and every map statement (map_Kd, map_Pr, map_Pm, map_d, norm, map_Bump) becomes a texture node reading that image file. An object using several materials keeps its first one.
