Well, let's show you a few of the renders I did for educational purposes; a short story about a boy in 1243 fleeing an enemy and hiding by his brother's grave in a crypt, before being found again by his father, sort of. Buildings done in Lightwave, people in DAZ and Marvelous Designer, veggies in Speedtree and all rest in TG of course. Crypt was a bit tricky, but with 2 local clouds and (angled) simple shapes, photo of church interior on card, and some spotlights, I managed to get this haze thing together, even in RT it worked well enough. PT would work better, but it was all done in a hurry.
The grave stone was just a photo, from which it was quite impossible to make a decent bump/displacement map, but so be it.
