Correct:
Incorrect:
I have a simple App, which tells OCCT to read and mesh a STEP file. The result is written to a VRML file.
The writer seems not to find the material. According to 0032728, I tried XCAFPrs_DocumentExplorer. It finds shapes with colors, but VrmlAPI_Writer does not use this explorer. Don't know, how to fix this on my own.
Expected Behavior
Colors on all levels of the hierarchy should be found and written into the VRML file
Actual Behavior
Appearances defined directly on meshes are being converted correctly, inherited colors not
Sample Code or DRAW Tcl Script
int Step2WrlConverter::Convert(char* input, char* output, double deflection, double angularDeflection)

app->NewDocument("MDTV-XCAF", doc);
auto success = reader.Perform(input, doc);
if (!success)
