Re: Weird wavy lines and streaks

Attached is a crop of an outdoor/night scene I am working on. If you look at the entrance doors, the aluminum mullions are all wavy looking, and there looks like an overlay of some sort of little lines instead of noise. Hopefully this makes some sense when you look at the pic, most noticeable in th...

I'm still thinking about how to handle the volume data formats etc... Any more suggestions are welcome! Off the top of my head :) Assuming you're using grids to represent the 3d data, the simpliest choice would be a spar list of 2d image, when storing the datset on file each 2d image can be compres...

Re: Heads up on coming enhancements

- an alternate bloom function, based on diffraction-limited bloom in real lens systems, that provide much better results in conjunction with linear mapping. fwiw, I understand that the bloom functions have ben optimized, and may no longer need auto-update. But this one does. It requires a full imag...

well normaly ior of 1 just equals completely invisible, but my fresnel settings should be making the sphere darker at 1 or at least a bit reflective (i dont remember if i had reflect on or off on this test). but in my case the fresnel is making the sphere intensify the color of whatever is behind i...

just drag and drop *.nk or *.ior file anywhere inside the app's window and copy the result rgb colour. It should read *.nk, *.ior with measurement in electron volt (1), micrometre (2) and nanometre(4) Hey dude, the drag & drop Stuff doesn't work for me :? You are linking to the same file like in yo...

could you add a reversed version? I'd like to use nk-ish things with SSS or difuse (which actually should be possible by using Exp 0-1) or st. like that :D AND it would be great, if you'd add the IoR, too. Those balls look great, already! As requested :D http://www.renderlight.co.uk/files/rgbtonk.e...

What's all this recent fuss about custom nk materials? What's the point of setting a single colour, then calculating the nk values for it and using it for a material instead of a phong material with that specific colour? The main reason is to provide the user with a start point to create custom nk....
