Hi,
I'am newbies on POBray.
I want to know if it's possible to make a global setting for the part {finish}
on CSG object ?
At this time i must replace all the line code one after one and it's very long.
How can i do this ? using global setting or using teh replace function on the
editor ??

I use POVray for windows

Thank for your answer

Vincent GALLAY

You can't override a yet defined texture for an object.
What I'd do is #declare a finish as
#declare My_finish=finish{finish items}

and replace all finish statements in objects textures by
finish{My_finish}

This way when you make changes in My_finish, you doun't have to edit all 
objects textures


You'd be welcome too on the french POV-community news server

I think "ambient" is the only one you can set globally. However, you can declare
a texture as a varaible and then use the variable wherever you need it instead.

You can set any texture as the default one. For that, you need to use a
#default{...} block early in your scene.
Sample:
#default{texture{pigment checkers}finish{ambient 0.5 diffuse 0.5 brilliance 12}}

After that, any object that don't have a pigment deffined will have the default 
checkers pattern. Any texture that don't have a finish statement will get the 
finish stated.

You should apply the finish to the complete CSG object by placing the finish 
statement at the end of the CSG object, after all of the components. It's usualy 
beter to place it before the eventual transformations applyed to that CSG object.

Another way, is to use
#declare Name = texture{pigment{Some_Pigment} finish{Some_finish} }
early in your scene.
The name can be about anything, must start by a letter. It GREATLY recommended 
to always start the name of user-deffined variables start with an upper case letter.
That way, the various textures, including the finish, are regrouped toggether 
near the top of the scene, making it easier to find and edit them.
If a texture is used in several places, you only have to edit it once to change 
it everywhere it's used.

This is my favorite method, though I usually only use it to bring the 
default ambient value down to 0 for every object's finish. I use it in 
every scene I make, because I never did like the standard default 
ambient value as it tends to be somewhat unrealistic.

Nice tip! I didn't know that.

It's not limited to finish, pigment or textures. You can have a complete material.
#default{material{
	pigment{rgbt 0.8]
	finish{ambient 0 diffuse 0.1 reflection{0.01, 1 fresnel}conserve 
energy}interior{ior 1.38 fade_color rgb<1, 0.31, 0.84>fade_distance 0.1 
fade_power 1001
	media{scattering 1 rgb<0,0.6,0.1>}
	media{emission rgb <0, 1, 0>samples 99}
	}
}
