PUT_COMB

## Name

put_comb — Insert combinations and regions - allows definition of both boolean expressions and standard attribute values.

## Synopsis

`put_comb` {`comb_name`} [is_Region [[id] | [air] | [material] | [los]] ] {`color`} {`shader`} {`inherit`} {`boolean_expr`}

## DESCRIPTION

Command for inserting regions and combinations with attributes set using a single line command - useful in scripting situations.

## EXAMPLES

The put_comb expects one of two particular forms of input - combination or region.

Example 1. Specifying a combination using put_comb

`mged>``put_comb test.c n 255/255/255 plastic n "u sph.s u arb8.s"`

Creates a combination that is not a region, using the plastic shader, consisting of the union of sph.s and arb8.s".

mged> l test.c
test.c: --
Shader 'plastic'
u sph.s
u arb8.s
mged> attr get test.c
oshader {plastic}

Example 2. Specifying a region using put_comb

`mged>``put_comb test.r y 1001 0 32 1 255/255/255 plastic y "u sph.s u arb8.s"`

Creates a combination that is a region, with region id 1001, air flag off, material 32, los 1, white in color, using the plastic shader, inheriting, consisting of the union of sph.s and arb8.s"

mged> l test.r
test.r: REGION id=1001 (air=0, los=1, GIFTmater=32) --
Shader 'plastic'
(These material properties override all lower ones in the tree)
u sph.s
u arb8.s
mged> attr get test.r
region {R} inherit {1} oshader {plastic} region_id {1001}
material_id {32} los {1}
