Hi glmr,

I have been using Modo to render MOI models for some time and it works very well. MOI had a good export function for the Light Wave format which is native to Modo. It has become more expensive (and complex) over the years but it is a full featured modeling, rigging and animation program. The rendering engine is very flexible, fast and produces excellent images. I find the rendering interface very human-friendly. There is a demo available if you want to try it. Good luck and happy rendering. tc
