overlay screen with .tga-file

[Ravenskull]

Hey,

another question came up when thinking about my mod concerning screen effects. At a specific point in Penumbra you had to use a gasmask to cross an area. I want to use the same quest in my mod (Amnesia). Is there an option to overlay the screen with an custom .tga file? For example if you use the following script:

GivePlayerDamage(30.0f, "damage_bloodsplat1.tga", false, false);

... the bloodsplat tga-file will appear.
If I try to use my own file, by simply replaceing my own file it will not work.
example:

GivePlayerDamage(30.0f, "gasmask.tga", false, false);

It also doesn`t work if I replace the original file by my own custom file.

Is there an option to make the programm recognize my file?
I´m also searching for an script to overlay the screen with an .tga-file permanent.
If theres a way to realize my idea it would be a nice snack for all players.

Thanks for your support,
Ravenskull

p.s. Demo is coming soon !
