Deep breath guys!
Just want to clear a few things up. I made this mod EVL compatible for a few reasons:
I am lighting freak and I really like flexibility a mod like EVL affords. I've been dying for a traffic adviser, and now i am have one that is close.
It is much easier to setup (for the mod maker anyway) than using the stock sirens. No trying to guess where the siren will pop up, or whether you got the scale and offset correct, not messing with the siren settings lines in meta files, etc. You put the flash object in the correct spot in it's actual size, group it with others that you want it o flash with and boom, it works.
I knew i was going to make the jump ELS as soon as it was released, so experimenting with EVL should allow me to transition, with little effort, to ELS as soon as it arrives. EVL is a stopgap.
That said, i realize that ELS and EVL is not everyone' cup of tea and the approach it takes certainly has it's drawbacks. Perhaps it's biggest Achilles heel right now is that there are currently only 9 extra slots are accessible to use. That sounds like a lot, especially since you can put many flash objects in each extra (unlimited really), but each flash in an extra all have to share the same local pivot, as far as i can tell. Why is that a limitation you ask? well, its only really a problem on parts that move. Take the doors for example, you'll notice i no longer have lights on the door mirrors. Well that is because the when the light was flashing and you opened the door, the light would still flash as if it was closed. To make it work, i would have to nest the extra to the door as child object, so that when the door object rotates, so does the flash. But that would force all the lights being used by that extra rotate too,which of course would look odd. I could just use extra 1 and extra 2 only on the left and right doors, but that would leave only 3 and 4 for the primary pattern. and that may very well work, i need to try it and see. Another option i was toying with is using a combo of stock sirens and ELV, use the stock sirens on the door mirrors, and other parts that open (boot for example, but since that is opened much less then doors, it's not as bad) ELS may very well have a way around this problem, and i hope it can use more extra slots, but time will tell.
Why am I telling you guys all of this? well, i guess to let you know in the world of modding, just like real life....everything is a compromise personally i choose the path that gets me as close to my vision for a vehicle as i can get.
But to answer the question asked, i will certainly consider making a non EVL/ELS version after i get this version out. But it will probably be a slick top ;)
