first try in INDIGO need help

yeah it makes it the reflections clearer, but if you have a really fine bump map for the grooves, it will appear as blurry anisotropic reflections.
its like the trick in Blender to get blurry reflections: you just add a really fine noise bump map and adjust its power to get the degree of bluriness and antialias the shit out of it. same idea but using grooves intsead of dots.

Maybe boost prescale and burn x2/x3 each, in order to "dull" the specular without loosing too much dynamic.

do i love to come back hours later to see that one object was misplaced

argh ...

also the hour glass did not have sub-surf turned on.

what do you guys think sofar? This is just my first project with Indigo so be nice

the brushed metal look seems to help when you need some semi blurred - stretched reflections but it seems not to work very well with stretching the specular reflection !!!

the big problem here is also scale and detail. the mayapple is much smaller than the hourglass and somehow when you apply a texture to it you need to keep that in mind. i wish that indigo could use procedural plug ins to to those things !!!

I think that your brushed metal aspect is good. Maybe you could make the reflections a little bit harder ? (by adding more exponent if I'm not wrong)

I need to rework the texture sizes a lot.

hu i noticed that in case the map is to fine you get some crazy moaire artifacts...

I just really wish there would be a procedural function to calculate a fine groove grid independent of the mesh size.

Looks great, so far! Many improvements

thanks, I only can say thanks a lot for the help here from Manitwo.

He gave me a push in the right direction.

you mean the can-light-setup? It's great indeed!

oh yes!!!! the spot light idea for the background and the light box idea were things i never thought about sofar. i always stuck light meshes into the scene.

hey guys

the rendering is now working since around 9 hours and i do not see any change in the grain?

the silver surfaces have a very fine brushed bump map.

any tip? because otherwise I would call the rendering be done and
reduce some noise with neat images or so.

claas

The less grain there is, the longer it will need to disappear!
This pic is already very clear, but for complete clearness, you'd need to at LEAST render it for 24h, I guess...

Have you saved igi ?

If yes you can try to resume the image with lower <max_change> and
<large_mut_prob>, maybe divide them by ten for a start.

This is experimental

EDIT@OnoSendai: Obviously at a certain point Indigo has covered
the range allowed by these settings, igi format would allows Indigo to
resume itself with updated settings (based on harmonics of the former
ones) isn't it.

jesus, it finally starts to clean up, after 18 hours.

so obviously brushed and bumped surfaces with refection's in it are a time killer

Did I understand it right that when I kill the rendering right now. I could resume it later again because I saved the igi file?

How do I do that?

Code: Select all

indigo -r image.igi scene.xml

To ensure that works its better to type full paths for all three terms.

like:

Code: Select all

c:\indigo\0.7t5\indigo.exe -r c:\indigo\0.7t5\renders\image.igi c:\3d\scene.xml
