delphi - how to change the color of 3D firemonkey objects from different thread -


i have cylinder

cylinder1 : tcylinder;

and want change colour when click on it. i've added on click event

procedure tfrmfiremonkey.cylinder1click(sender: tobject); begin     cylinder1.materialsource := greenmaterial; end;

the cylinder not change colour. change colour if set cylinder1.materialsource before call form.show event

i suspect reason not showing because cylinder1click happening in different thread.

i have discovered that

procedure tfrmfiremonkey.cylinder1click(sender: tobject); begin     tcolormaterialsource(cylinder1.materialsource).color := clablue; end;

works fine
