I tried to do the little 15mn challenges and... well it's fun ! I had already done a lighter before, it was in fact the first object i have modelled . It was funny to see how i can make one now in limited time . Then, for the mailbox, i've been stuck for a few minutes because of a bug concerning the bump : when you rotate an object, the bump goes upside down, in a way . So i had to play with the texture, the orientation of the plane ... When i asked the question to Metacreations support at the time, they answered me it was due to the nature of the rendering engine, and there was nothing to do about it . So if you encounter this problem, just think french and say "c'est comme " or "c'est la vie" ! Those challenges are a very good way to test your modelling skills, so i've tried some scissors . It was done in 16mn with vertex objects and a sphere . It was tricky because the shapes must be aligned and the result is ... well, scissors . And there is something strange: the edges are on the wrong side of the blade ! So if you wanna try this one, let's see your techniques for modelling scissors !
