Fix an issue where the visual plugin attempted to load the height, normal and tangent map textures twice when using displacement map rendering.
There is still an upstream issue in the
GzSceneManager
(gz-sim/src/gui/plugins/scene_manager
) whereby the visual plugin is loaded twice, causing performance issues, but this change prevents the segmentation fault that caused the GUI to crash.Applies to the
ocean_world.sdf
model.
