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 decimal 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, mostly taken from Enum-Polyflags.h:
| Bit | Value (dec) | Value (hex) | Name | Description |

| 0 | 0x0 | Use settings from Surface Properties for each individual surface of the brush. | ||
| 0 | 1 | 0x1 | PF_Invisible | Polygon is invisible. |
| 1 | 2 | 0x2 | PF_Masked | Polygon should be drawn 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 | 0x4 | PF_Translucent | Darker parts of the texture become transparent, see Color Blending. |
