Mostly Finished

I'm finishing up my Free Trader model. Took about a week to build from scratch. Some of those days were spent thinking things through first. I will redo the back end one day, to give the engines more substance than just simple flaring.

Here's a video on some recent changes made.

What a Piece of Junk!

I ran some white-wash over the ship in 3D-Coat, using a smart material. I first tried doing it while the ship was in several parts. But smart materials really do prefer to pour from their buckets at the same scale. Meaning, all the parts need to have the same resolution for their texture maps. It's part of the calculation smart materials do before the fill bucket is clicked.

So I welded the parts together that needed the same white-wash treatment done. They all used the same UV map, which I was hoping to avoid at first. I prefer to have a UV map for each object. But maybe for this model, it wouldn't kill to have one huge UV map. In the meantime, the separate parts that used different paint materials were left as individual objects.

Anyway, this is just the shell body. Ready for the scrapyard.

Boolean Cutting in Hexagon 1.21

I'd forgotten how good it works.

I spent a few hours, playing with different apps I have, doing various draft models of the Free Trader. It will be a lo-res model when completed. Something that I don't want to spend more than a couple days on. Which meant Hexagon would be used. Ha!

Amapi Pro is great at NURBS. But it is a terrible box-modeler, which I was finding worked better for this kind of object. I had forgotten that Hexagon does boolean cutting, which speeds up the modeling process as well. I'm hoping I don't have to do too much clean-up work on the mesh, once I'm done cutting chunks out of it.

Because I'm old-school, when it comes to modeling Traveller ships, I tend to use only the first drawing made of a ship for reference. I have no idea what the back or bottom of the Free Trader looks like, because there is only the one image of it in The Traveller Book hardcover on page 64. Maybe I have some notes that I took about that back in the day still. Otherwise, creative license as usual.

Like all models I make, this one will also be done by eyeballing things. No tracing.

Updated the model some. Getting ready to UV map it.
