First test, 2min,40sec on a DuoCore 2.4
This test use GI

Found it cool that the first test gave real nice results,
some glitches here and there, still fun stuff.
Should have bought this plug before :slight_smile:

Tried using clipmaps, works, but not to much to win, rather the other way around actually…

Rendertime 3min40sec
…thing is, the Antialiasing process is what takes the time,
if there is a magic way to make AA calculate faster, please do tell :slight_smile:
Maybe Kray would be the way…

#3

Maybe rendering double sized image and then resizing it back to half in PS would do the trick…

#4

Yep,
That’s what I did :slight_smile:

It still is slow though… and the alternative using AA is slow, heard good stuff about Kray, it also has built in instancing. If I had the money…

It is hard to cut down rendertimes, luckily GI is fast now,
getting a new Cpu wouldn’t hurt either… :slight_smile:

#5

uhmmm, do you really get any benefit from using GI for grass? Im quite sure you can get the same results with a normal setup with a few lights or textures to control…

:wink:

#6

I calculated,… :lightbulb and yep, GI wins :slight_smile:
Thing is, this is grass, so I can use quite bad GI settings in Lightwave, since there isn’t too much realism to pick on. So basically the above is superlow GI quality.

I tried RayTraceing only, and the results are good, but because of the AA that is needed (I was partly wrong akademus, turns out I did use AA on that render, for later to scale down in Photoshop)

So, long story short, i only saved 20 sec’s on the render below

Hope I get that Quad Extreeme for Christmas… come on Santa… I know you can be cool this year…

#7

aaaahhhh Whats GI? :shrug:

#8

The top one,

for most ppl I guess the bottom Raytraced example (post #6) would be more than satisfying :slight_smile:
the top example has a glow to it because of the GI, that is why I like that one more.
…could be with more experimentation I could get the bottom Raytraced version closer to the GI version.

(then again, the AA is what takes time, so unless RayTracing can save time I don’t see the point of not choosing GI in this example)

#9

think hes asking what is Global Illumination :wink:

#10

Oh, :slight_smile: hehe, I have the flue, please forgive me today :slight_smile:

#11

And that equals to what?

HDR, ambient light, radiosity, caustics …?

Sorry never heard the GI word before…

Unless of course for…

#12

it is basically the same as radiosity :slight_smile:

(nice render :wink: )

#13

just one question, is possible bake the instances ?

#14

No, not that I know.

#15

i’m trying to play whit the demo of hd instance, but i have some problem for the correct placement of the clones is possible attached the instance to the normal of poly ?

#16

Hm, hard to say, looks like a random rotation setting or something.
There are some tutorials on the HDinstance page that could give some clues
My guess though is that it is just a simple wrong setting somewhere, a numeric value, duplicated geometry or points, or such… sorry, hard to say from this point, if you attach the file I can see if I can take a closer look.

Btw, here’s a nice video, though not all that related.
Never the less, nice intro to the plug.

umm, as we know HD instance couldnt work with fx emitters but partigons…
my question is, how do you create partigons? and how (what button) to change each of the particle emitters to objects?

thanks :smiley:

edit: found the ans, :smiley:
