et_fone_home, in my case, it was not a matter of lighter/darker, but it was because I've changed the global illumination method, and this one grabbed less light from the dark background (dark but not completely black)
Nitro-x, thanks for the compliment, but like you said it's really early to bet. About the rear being a bit unlighted, I've increased light intensity, check the render below. It's not perfect, but sufficient for WIP renders.
ROcky103, thanks for the compliment. The main slow-down sources were :
- The number of samples in each light : 10x10 was overkill. I reduced to 8x8 in the previous render (and in the one below too) and it's enough I think. I should try 7x7 or even 6x6.
- The GI model : without GI, there is no blue tint brought from the background. So GI is mandatory. But in 4h render, I used what is call "Full GI" in YafRay : light rebounds are computed between each objects. I moved to "Sky dome", which is lower quality but faster : it works like an AO, taking care only of background and one object at a time (no light goes from one object to another one)
The 4h render setup is pretty cool, I will keep it for final renders.
The model has only one little change : I replaced a metal plate with a glass on the side to get more visibility for the gunner.
