mirv_movie_separate_hud 0|1|2

• Default: 0

• 0 : no separation

• 1 : separate HUD stream + HUD alpha stream

• 2 : separate HUD stream only

When being separated none of the other streams should contain the HUD.

In some cases the hudalpha stream might be empty (completely white). This is due the OpenGL window's frame buffer not having bit planes reserved for the alpha component. There are 2 different methods than can help solving this problem:

Make HLAE explicitly request alpha bit planes from the window system buffer::

Tick "Force 8 bit alpha channel" in the advanced settings in the launch dialogue.

In case you have a card that support the EXT_framebuffer_object (see GoldSrc:Render Settings), using this target should solve the problem too.

The hudalpha stream is used to to blend a black layer above the game footage. The hudcolor stream is drawn additive on-top of all.

• 1st layer: hudcolor, composite mode: Add
• 2nd layer: hudalpha, effect: invert, composite mode: Multiply
• other layers: game footage etc. goes here

Also see Compositing in Vegas Pro.

(per pixel)

C - hudcolor
A - hudalpha
S - Source (other footage)
T - Target (composited image)

T(C,A,S) = (1-A)*S +A*0 +C
