In the program Contextcapture viewer you can turn on/off textures of a 3XM-file. This option I would like in the Reality Mesh Attachments-dialog. And so you can use a textured mesh also as a untextured mesh in your DGN-files. This should be expanded to the visualisationsofware like LumenRT. Or the wireframe-option and other displaystyles in Microstation. Like the normal referenceoptions.
Editing display styles doesn't work. Removing pattern maps it shows as wireframe but no option to remove textures but keep fill. Also overrides doesn't affect reality meshes. This option should be easily switched on off as needed for digitizing reality meshes to check surface noise.
