Hello everyone!
This week have been very interesting with tons of researching, experimenting and testing the TV filters and FX (Shader) files.
What I have learned so far with this theory from observation and countless testing;
SF2 Engine does not allow us to direclty mix the shaders with 3D world for TV screen via radar texture methods. (UseRadarTexture=TRUE), BUT it does allow us to use sampling to add the 'tilted / hue colors' to the TV.
After testing various .FX, including FLTDTVFILTER.FX, turns out that TWCOLOR1.FX and TWCOLOR2.FX works because it uses sampling methods.
However, after testing TWCOLOR2.FX, what I learend is that only one of colro can be used with taht FX due to Alpha being 1.0 by default, which mean, the last texture laoded will overwrite the first one. Fortuantely, it got fixed, by setting Alpha to 0.5, which allows me to combine any two colors that would give me various colors.
For example
I have various color texture (mostly JPG, except for Alpha one that have invisible color)
When testing with two colors with updated TWCOLOR2.FX, used this folowing codes in .INI FILE:
The result in-game (A-4E '65)
I was even more curious, what happens if I add third color?
The resault:
I have many files to share here, so anyone can have resources, information, and files to experiment with, not only TV, also any thing else in SF2.
IN the files "TW SHADER FILES.zip" it is extracted files using SF2 Extractor and the file names inside each file's header are corrected to avoid the confusion.
TW SHADER FILES.zip
And in the file "TW SHADER FILES - NEW", there are updated TWOCOLOR2.FX, along with new TWCOLOR3.FX and TWCOLOR4.FX, you can experiment with various texture files.
TW SHADER FILES - NEW.zip
In the file "TW FX FILES INFORMATION.txt", it contains summary of each shaderas. It seems too bvious for us who already are familiar with it, but it does not hurt to at least have it. I used SearchGPT to assist with me. WIthout it, it would have taken me too long time.
TW FX FILES INFORMATION.txt
Finally, the file "FX FILES CONTENTS.txt" have long list of Shader's codes, consdier it as 'hand book" for quick references to any shader codes.

RIght now I am continuing to experiment with many thories I have about sampling techniques to turn TV into grayscale for early CRT TV in early cold war aircraft.
