Gyratory Tower Model Rendered in Cheetah3D

Here's the model rendered in Cheetah 3D – as close as possible to the original SketchUp model (see previous post) to allow for comparison between the effects obtained. This is another HDRI render, using the sky background from the SketchUp render as an HDRI to 'light' the scene. That's why the surfaces are picking up and subtly reflecting the colours from the sky.
I've deliberately left the Radiosity samples on this render low, because it gives a nice 'fractal noise' mottling effect to the structural surfaces – it lends it a bit of surface 'wear & tear'. However, I can't help feeling that there should be some sun reflections in the glass – I'll have to try and fake that.

Another quick animation to test out Cheetah's Spline Following and Target tags. The YouTube compression spoils the subtle effects of the HDRI shading, unfortunately.
