some bugs (mostly concerning rendering)

Got to report some bugs, but not sure if all of them are really bugs or just not yet implemented features.

All tested with the nightly build from March 11, 2011 on Windows Professional Service Pack 3 and Aqsis 1.6.0 installed

First, when I want to change the resolution in the rendering settings tab, it is impossible to set up my screen resolution cause the sliders for Width and Height are way too sensitive. My suggestion is, to remove the sliders for Width and Height and instead put 2 fields where the user can type in the resolution for Width and Height with his/her keyboard. I think that would be better.

Second, the dark skin is not being rendered yet, it is rendered just like the bright skin.

Third point, the hair. No matter which hair style and color I choose, the hair is always rendered blonde and only a very few lines, even with maximum hair width on.

Another strange bug I just encountered now: I have loaded any african ethnic, chosen a custom hair style and color, then went back to macro modeling and moved any slider, and the hair color switched back to the default black color that is displayed when you don't change the hair color.

I think the rendering right now is extremely slow. It was so painfully slow that I halted my development until Manuel could add some user options (like removing subsurf and other rendering beauties), I will try in the coming days to add this option myself.

Now getting back to the hair. Go to Rendering->Settings , there you will see a few rendering options (that funnily involves the hair as well). If you want more strands than just a "few lines". Add to the Clump children (recommended around 3) and multistrand Children (recommended in the 50 range). Currently we have only grouped the "Traditional Long" hair, which means that the multistrand interpolation will work there only. So you can try it with the traditional long hair. The traditional long hair has around 10-12 guide groups (to understand these things you can look at this tutorial). The average human hair should amount to 10,000 so make sure this formula holds : No. Clump Children x No. Multistrand Children X No. guide groups ~ 10,000

Hair width does not affect rendering, it affects only the output mesh from exporting hair as mesh. At the moment hair width is just there to give a rough idea to the user how the human mesh would look like with those hair width.
