Supported Render Engines 

Ornatrix App renders in two ways: built-in physically based renderers for previewing inside the application, and export to standard interchange formats for rendering in any external engine.

 

Built-in rendering 

The App includes two physically based preview renderers, so you can light and look-develop a groom without leaving the application. Choose between them (and the fast working view) with the viewport display mode.

• Cycles - a full, interactive path tracer, selected with the Realistic display mode. It traces global illumination and shades hair physically, refining progressively as the view settles, for the highest-quality preview in the App. See Rendering with Cycles.
• AMD Radeon ProRender - a physically based renderer with environment, area, and point lights and MaterialX materials, selected with the Raytraced display mode. It converges very quickly to a clean, stable image. See Rendering with ProRender.

 

Rendering in external engines 

To render a groom in another engine or pipeline, export the hair and render it there. There are three common routes:

• As curves - export hair to Alembic or USD as curve data, which most modern renderers can read directly. See Alembic Export and USD Export.
• As polygon mesh - convert hair to geometry with the Mesh from Strands operator, which also generates UVs for shading, then export the mesh. This works with any renderer, since it is ordinary geometry.
• As spline curves - convert hair with the Curves from Strands operator for renderers that render splines as hair, with UVs derived from the distribution mesh for texturing.

 

Choosing an approach 

• Use the built-in Cycles or ProRender preview while grooming and look-developing.
• Export Alembic or USD curves for renderers with native hair-curve support.
• Convert to mesh when a renderer cannot render curves, or when you need explicit geometry (for example for real-time use or 3D printing).
