Hello
Congrats on final release of 4.0.1,
Im not sure if its a forest bug or octane bug...but i think its forest's
if i choose "movable proxy" for forest in octane properties and using the std plane object of forest..whenever i change the density of the planes..all is well, i mean, both max viewport and octane update with no issues..but as soon as i change the std object to a 3d one from the library,the object disappear in max viewport, i have to press "update render geometry" on the octane window, for them to show up in octane..and do a slight pan in max viewport for them to appear in the max viewport...as soon as mess with the density parameter to reduce or increase objects in max viewport..they disappear again, i have to re-press "update render geometry" on octane again for the objects to update in octane and max again..
