Piping curve - same material reads as different

It’s great D5 shows Rhino’s native curve piping so that less geometries are made in the model. However, the material is a bit off.

All curve piping is applied with the same material, and D5 shows it as the same material. However, when that material is changed to illuminated, only one curve pipe that’s selected in D5 gets illuminated. All other curve pipes are not illuminated even though D5 shows it as same material. You have to select each pipe and turn on illumination.

Is this a bug?

Hi @bcsadmin

Did these pipes have the same material assignment in Rhino before syncing to D5? Also, could you please send a short screen recording showing the problem, and your Rhino plugin and D5 versions. Thanks!

Does this not happen on your end?
