Hello Evgeny, thank you for your reply.

Yes, i would like to use something like array modifier on the fly with different values (There are some more interesting modifiers also). That would be very nice feature. Of course we can make the same using code. But this would be the same workflow like in three.js also. I search for any points that would make our workflow more effitient if we use blen4web instead of using three.js.

Can somebody say how to change any modifier value on object from node editor or code? Thanks!

P.S. I want to load this value dynamicaly from json and then aply to any custom parameter or modifier value.
