Broken Material System

the "upgraded" material system seems to be broken or not working correctly. the normal maps on terrain blocks, imported from heightmaps or created within the world editor, are not visible. tested with generated normal maps from blender and with the shipped normal maps from "johnson valley".

recreated the exact terrain dimensions and texture dimension of johnson valley in a clean template and mapped the original normal map from johnson valley to the terrain. all measures and requirements for correct mapping of the textures were matched.

all textures are visible except the normal maps.

on the contrary all normal maps on imported static objects are visible and mapped correctly.

maybe it is a bug related to the world editor. if yes is there any workaround for this?
