Animation

Ok here follows my animation playblast. I must say animating all the stalagmites was a really tedious job... And the rig itself sucks, so I couldn't pull off everything I'd like to put in the animaiton.

Final "God rays"

The light and rays got somewhere to the point where I'm quite happy with what I see, so I will be working on the animation of the monster and after that I'll delve deeper into SSS of the monster...

Test render

The scene is coming to the final look I'm going for. There's still work to be done on the ceiling in terms of modelling. Also  the matte painting will be improved, because right now i have a quick 15 min roughed in background. The "god rays" are still work in progress, because I want to experiment with different versions of shapes, intensity, etc. 

and here's a bright rays version (very quick setup, the contrast will be changed back to normal, but i might use bright rays on the right, because i like how they work with the character)

"God rays" test... work on light and cave is in progress...

Video test

So here's my video test - crude cutout from the green screen and simple composition with one render. Just to check how it works together. Also now I'll be able to make a final decision about composition of
the shot.

Subsurface scattering test

Here's my SSS test. I'm still working on the material, but it's already moving towards the look, I wanted to achieve.

Render test.

Modelling of the monster is almost done. I'll do some more work on the slug's body and that's it.  Those are test renders with high-poly mesh (lower part 500 polygons, inner mouth with teeth - 400k), bump maps and the approximate light setup i'll have. Models don't have any textures, just blinn applied to them. All in all so far it works fine -  renders one frame in 30 seconds.
