Select "child" of FBX import

hi

it seems i can’t select a part of an imported FBX (exported form 3ds max) file.

for an examle, i import a house and want to turn of Mesh Collider for the walls, i can’t select the walls, all objects seems grayed out in Inspector :-/

i’m quite sure i could do this earlier, but not now :frowning:

what am i doing wrong?

thanks in advance

doh - found out - i selected objects in the asset browser, not the hierarchy browser.

what a noob error…
