Maya : Environment for chrome

Posted: June 05, 2006

What's a good image map, to map onto a sphere (as a cheap environment) so that chrome can reflect something?
The one I made makes the reflections look bleh

You need hdri

Well... it doesn't need to be THAT accurate.
I'm not using it to illuminate, just something to reflect.
Just looking for suggestions of types of photos / modifications to them that make decent reflections

Use MRs env.

Natashka1954: that makes a big enough difference? I thought it was just a mapped sphere too?
Posted: June 06, 2006
Vertox
Its for realistic reflections important too

Vertox: you have a point. I'll have to search for some free HDRI images.
Posted: June 06, 2006
Vertox
It would be the same as if you would create a sphere with spherical mapping
Free good hdris are hard to find
I would say i haven't found any
Except you make a church scene
Or something in that uffizi court
;)

You can also use animated caustic movs

Heh, I don't have the time to set myself up to make HDRI maps now.... man someday. =P
Its such a frickin' sweet concept

I did my own hdrimaps
But since i have no good program to work on those i have composed them so badly

There are free hdri out there in the web
Posted: June 07, 2006
Vertox
But there are really only a few

Free there, but they seem kinda low-rez.

How big is your scene?
Posted: June 08, 2006
Vertox
You don't need highres for most purposes
Posted: June 08, 2006
Vagon
Not big, it's just a single object
Posted: June 08, 2006

Wouldn't think if its only reflections
How would you go by creating the reflection environment - put everything inside of a sphere and texture it with your refl. map?
Posted: June 08, 2006
Vagon
what I did is just made a sphere, and mapped a texture to it, then set the sphere's primary visibility off, and kept visible in reflections on

Vertox
Vagon: do you render with mr ?
Posted: June 08, 2006
Natashka1954
So you need a texture with lots of things - not so much the detail
Posted: June 08, 2006
Vertox
In mr you should actually use the ibl-node
Especially if you tend to work with finalgathering or other advanced rendering techniques
Posted: June 08, 2006
Vagon
Vertox, yes, of course =]
Natashka1954, pretty much. just curious what you guys use for this kinda stuff. (my original question I guess) =]
Posted: June 08, 2006
Vertox
Then you actually have to use it to reduce rendertime
You can set the ibl-node to spherical or angular projection
Posted: June 08, 2006
Vagon
Wow... IBL takes a lot longer to render
Posted: June 09, 2006
Vertox
Actually it should save you time
Maybe you have set it to cast light and shadow
Posted: June 09, 2006
Vagon
I did
Just wanted to see what the result would be
Posted: June 09, 2006
Vertox
Ok, then its your fault
You can't expect that to be faster...
Posted: June 09, 2006
Vagon
That's the thing I want to learn about IBL... making my own HDRI images and using it to light a scene
But I need a better camera, and the big sphere and the tripods and whatnots
Posted: June 09, 2006
Vertox
You need a camera that does multiexposure takes
I borrowed one from a friend
And made skyphotos
And assembled them in psCS2
Which is quite fast and yielded for my unknowing soul better results than hdrshop
But saving and loading and working with it in photoshop is really a pain
Posted: June 09, 2006
Vagon
Any idea why my environment color is now black instead of the color I set?
Now that I have an IBL node for my reflections....
Posted: June 09, 2006
Vertox
Its because that node is your background now

Vrugore
yes, i think so... Smile
