Tip's & trix..

We will make a separate area for tips and users best solutions for lightsetups but i take a first step and show you some new commands that are very handy in Kray 1.7.
First of all, preview size:
type in header "previewsize 1280,1024;"
Kray's preview window is set by default at a maximum of 800x600 even though you might be rendering to 1024x768. By typing in previewsize 1024,1100; or whatever you can customize this behaviour.
Local oversampling (experimental) typed in tailer
prerender 1,2,0.01;gradients_neighbour 0.01;
or another one
prerender 0.1,4,0.01;gradients_neighbour 0.001;
The first example will render 1 full resolution prerender 2 times if not the differences between cells are less than 0.01. If so it will only do prerender once. gradients neighbour is to controll what cells that will get more FG rays fired at or not.
In the second example it will only prerender 10% of the screen but do 4 passes until the differences among cells are less than 0.01 but it will update all cells with differences larger than 0.001 for each pass taken.
Local oversampling is maybe not an everyday tool but in highcontrast/strong indirect lights/hdri lit scenes this is VERY handy to improve quality. Try the above examples on a simple scene first and with rather low FG values like min100/max 250 and see what it does. For every pass done the irradiancemap will get smother and more detailed.
Motion blur:
Works when MB in enabled in LW and Grid or Random FullScreenAA is used in Kray.
Finalgather blur:
Very handy tool also since we can get smoother and clean results with less ray's with some of the presets it's default to 10-16 but try higher values like 32 to get rid of splotches caused by not enough rays.
ok these where the things on my mind for today. Happy Kraying.
