Legacy:PolyFlags

In the properties of a Brush, under Brush -> PolyFlags you can give all surfaces of the brush default properties that override the Surface Flags (UT) in the Surface Properties window.

In PolyFlags you have to enter a number, what follows is a list of the meaning of all the numbers.

To give a brush two or more properties at the same time, you need to make the sum of the numbers of both properties. For example if you want a Translucent + TwoSided brush, you have to use the number 4 + 256 = 260.

After you entered the number you need to rebuild to see the change.

Here's the list:

Bit	Value	Name	Description
	0	Default	Use settings from Surface Properties for each individual surface of the brush.
0	1	Invisible	All surfaces of the brush are invisible
1	2	Masked	Use for palettized textures to make the first color in the palette (in Paint Shop Pro at least) invisible, see Color Blending
2	4	Translucent	Darker parts of the texture become transparent, see Color Blending
3	8	Non-solid brush
