question about bsp

hi i finally got comfortable with the editor and started development, i just have a question about BSP, it appears that the exterior of the bsp is still being rendered, how do i tell the engine to not render it, i dont see anything about csg subtract, so i assume its all csg add, also the bsp no longer has face tags like “unlit, fake backdrop” ect. i jumped from unreal engine 2 to 4 so im noob please help! thanks =)

heres what i expect it to look like also see in the white window how there is tags to add to the face

but heres what it looks like in the new one

They removed subtraction type levels a long time ago during Unreal Engine 3
As for those tags, you would create effects like that in your material, like for instance you can change your material from Opaque to Unlit.

ohh ok, thank you man :slight_smile:
