what are these mistakes in my render??

Post by duke_leto_2 » Thu Nov 27, 2008 8:25 pm

i dunno what was wrong on the floor, floor is made from one box for sure, no weird pollygons there, the material has same tiling in bump mupping and same channel as diffuse. i don t know what happen to the wooden walls, the wire is correct for sure.. i think maybe i shouldn t put 10 value bump mupping there, i should turn it off..
what do U think guyz is wrong to my render??

cheers,
leto A.

Your render is too dark so I can't see the issue you are mentioning, but indeed don't expect neat results if you set you furnitures bump to ten meters !

In Indigo, 1cm = 0.01 units :!: or 1 indigo unit = 1m

Displacement mapping would do best for the panels, a strong bump as it is needed here will tend to make noise harder to kill than with displacement, it's better to use bump mapping for subtle effects.

If it was on the whole map, I'd say, what you see, are jpeg-artifacts... but then, you'd see them everywhere. So... Yeah, Bump of 10 is WAY too high...

By the way that was an important hint: don't use lossy compressed images for bump and displacement, choose lossless or uncompressed formats for these specific tags. While perceptually acceptable on colours, lossy compression destroys too much of the relevant data used to define slopes and details.

oh, on a side-note:
your ceiling looks pretty white... I guess, it's RGB 1 white... In this particular image, that might be fine, because the floor and door are such dark, but it will both add better contrast (more realistic shadows) and speed up your rendering, if you use only 80% white ( RGB 0.8 ) Infact, you might never want to go beyond that value.
