Looks very nice, Kadri. I always like to see new things from you.

Cool, Kadri! I can feel your pain regarding rendertimes
Indeed. Compared to years ago when the TG2 technology previews were around, the speed of rendering has greatly improved. But compared to other renderers, TG is still
painfully slow.
I've heard it said before that because TG uses procedural displacements and such that it is only to be expected that these things take a longer time to render but I've done lots of tests and comparisons of scenes which don't contain displacements and specialised TG 'things' that take longer to render. It is still
extremely slow.
As an example, I rendered a simple ray-traced animation in Carrara, which contained lots of moving objects(using bullet physics and gravity) casting shadows into volumetric lighting producing godrays in the atmosphere, the entire thing was rendered in a few minutes for a 250 frame scene.
If I was to render the same thing in Terragen, I'd be there for days, and that is
without any volumetric rays. For those, I'd have to first enable ray traced shadows in the atmosphere to get any rays to show up at all, and that multiplies already long render times by an interminable amount.
Terragen is such a great program that I overlook the render times a lot because I just really love using it and it does things that no other program can do but when compared to other programs, the render times are truly ridiculous. Not to mention the visual 'mistakes' that happen during sequence rendering, which mean you need to bump up render detail and quality settings to sky-high levels to overcome. Not good.
I always look for shortcuts when TG2 rendering and I'm quite pleased when I find I can tweak things in TG to reduce render time(sometimes by lots) BUT, that is a comparison of TG render times only, it's no comparison against other rendering programs. We all deserve a 3D renderers Patience Award for sticking with TG, it is very slow indeed.
