Yeah that's pretty much what I was referring to, what range of data is reliable and if the camera would start to have some type of responsiveness curve that would show up in the data. Does anyone have experience with Luminance HDR (qtpfs)?
use shape Square, don't have any grout initially, have high luminance variation, and use edge detect. Simple example here (combined two tile generated shapes, but not necessary), Edge detect will give you consistent grout.
MentalRay is a lot better with alphas from my experience Plug your map into the the transparency slot. In the alpha map attributes there is a drop down box for Color balance. Collapse that menu and check the box saying 'alpha is luminance' dunno why but it works
Very nice stuff. I like the subtle variation in the tiles, is that just some dirt? The edge wear is pretty cool too - how did you end up having some tiles masked out entirely? Was it the luminance variation added as a mask?
Hey Jesse, you can do bloom in max using a luminance blur. Just add a blur in the effects tab, then follow the values in the screen shot. But, If I remember correctly it looks a bit odd in motion. Either way, give it a shot. -Tyler
Well.. in the end it's just a mathematical model of the real thing.. just as the older ones two.. and not every PBR is the same just by using those letters.. Finally there is also spectral renderers.. maybe even computing spectral ares you may not even see (visual perception).. and then there are color management and even…
