I have an obj/mtl files that want to render in pv using the right material but the final image colours look so different.
In Ospray “ospExampleViewer vase.obj”
In Paraview followed https://public.kitware.com/pipermail/paraview/2018-May/042689.html
- Open vase.obj and apply
- Activate Ray Tracing, select Backend Ospray pathtracer
- Load Path Tracer Materials, change to mtl, select vase.mtl
- Coloring by MaterialIds
- Open Spreadsheet, Field Data to see the MaterialNames
- Open Color Map Editor, Interpret values as Categories and annotate the material names in the same order than the FieldData.
