yes I tried converting to poly before the fuse node, nothing changed. But as I'm now commited to the beforementioned workflow things are sort of flowing.
Thanks for the tips anyway! Will surelyl remember that for the next time. 2016-12-06 17:59 GMT-02:00 Nono <nnois...@gmail.com>: > Maybe you can't fuse because of polysoup or packedgeo, did you try a > convert node (to poly) or an unpack before fusing ? > > Be carefull with fuse thought if you fuse your surely have to do that in a > loop (just use the piece attribute) to prevent fusing pieces together. > > Cheers > > On 6 December 2016 at 16:32, Fabricio Chamon <xsiml...@gmail.com> wrote: > >> thanks Christopher!
