Conversation
Previously all materials are set opaque when alpha option is set to 1. With this commit the materials are set to their original state when alpha is set to 1.

Currently, rviz modifies a custom material setting loaded together with a mesh model, e.g. within
updateAlpha().This destroys, for example, transparency within those original materials.
With this pull request, the original material is stored additionally to the active one, such that the original one can be restored if needed. This allows to correctly render e.g. glass:
