[SA] How is particle.txd handled?

[S_G]

I'm trying to see if there's any way to increase the size of certain particle effects, such as the one in particle.txd called "headlight", which represents the light texture emitted onto the ground from vehicle headlights.

 

Changing it in the TXD seems to have no effect on the overall size of the texture in-game. So, I noticed effectsPC.txd has effects.fxp, which is a text file that contains a lot of information about the TXDs and options for rendering them. However, I cannot find "headlight" to be referenced ANYWHERE except in the SA EXE. Does this mean the only way to change the particle size is to edit the EXE?

As it is displayed as a set size on the ground, changing the size of the headlight txd does not make the light pattern bigger. You can "optimize" how much light is projected, but there is only a certain amount of space for it. This is one I made, that makes better use of the space.

Ah, I see, thanks for the info. Might have to give your method a go for now.

 

Is the fixed size in the GTASA executable itself? Also, how does the game know to access get the "headlight" texture from particle.txd? What I mean by this is that I'm thinking about some method to increase its drawing distance, if not the size. So, if it could be moved to effectsPC.txd, I could use effects.fxp to attempt an increase in its draw distance. Otherwise, it seems that the game itself would have to be hacked to somehow (probably in memory) increase vehicle/light draw distance. Might even be linked to the vehicle spawn/delete radius.
