Morning Maelstrom;
I, too, wish the inworld building tools allowed more options for tweaking shapes. I am just a beginning art sculpter, using the inworld tools available to me, and it is definately a challenge to create what I visualize. Many times I begin, only to realize, what I want cannot be done, and have to scrap the idea.
That being said, I am curious to learn more about the programs that do 3D modeling. A friend, who works in this medium for a living, told me that I will be awed by what I can create and accomplish in these outside software programs. I must admit, I am a bit intimidated, by the new learning curve I will have to master, but excited to see the possibilities.
I do wish LL would expand our inworld tools, and agree with your post 100%, but I believe this is the way of the future and I must embrace the new technology.
