Hi Will, welcome to MoI and to the forum!

That's a beautiful model and rendering, I'm glad that you are enjoying using MoI.

It won't be much longer before MoI version 2 is ready, which has quite a lot of improvements from the v1 trial version that you are currently using.

There's a collection of all the release notes on the new stuff in v2 here:
