Thanks for the hint which I'll keep for when I'll use IFS stuff Here I used _Folding2/_reciprocalZ3/SierpHilbert/_reciprocalX3/_incylindrical; this last one always amazes me and I use it to bend otherwise rectilinear architectures
I don't think so, it mostly depends on the formulas used. I am using an old computer actually (not even mine) but when I find formulas requiring too much rendering time I just take them out of the equation In this case I always find myself working on fast rendering stuff
ah... well for me, maybe its the graphics card, although Luca said that has nothing to do with the speed... I just know that on my machine, reflections nearly always take longer than the actual render... I usually try to use faster formulas too... but that doesn't always work, some image i find in the Navi are just too cool to ignore, and then the main render turns out to be 12 hours or something...
I wish we could take some data about rendering time on different machines, to sort things out. I refuse to undergo a half day render because I can't risk to burn the only computer I have. Once this is gone I'm out forever because I can't buy another one For me an unusual rendering time is about 90 minutes, plus a couple hours for reflections. One day a deviant whose name I can't remember told me that the raystep multiplier can be changed after main rendering and before calculating reflections, because it acts only when you start a calculation (main one or reflection or hard shadows or whatever). I tried it, and sometimes results can be weird but you could try increasing the raystep multiplier before starting the reflections and see if the result is nice. The time required will surely decrease. I also increase a lot the stepwidth limiter when quality doesn't need it, and I prefer to render double size with AA than having a raystep multiplier excessively low.
hmm, yes, I can understand that... I don't know what I would do if my machine quit on me either, as I don't really have another... I could maybe scrounge up a older motherboard, but of my drives fail I'm probably done as I don't have replacements for them... but I often render things overnight because it's about the only way to do them.
I didn't know you could change Raystep or anything after the main render, I may give that a try, thanks!
