Hey mate!

For what it's worth, my recommendation is:
-GWX 2.0
-Combined Scene and atmosphere by Reece
-Realweatherfix

Reece's mod contains a SH4 scene.dat of some sort and a well done reworked atlantic ocean color, really nice...
Haven't noticed the effects from Realweatherfix yet, but apperantly it should be effective and be working fine together with both Reece's mod and GWX.
Lot's of great mods and WIP's out there! Gotta love the modders of this forum!

Following conferences with GWX hex editors Privateer and Ref, and in keeping with previous statements made by myself and Racerboy elsewhere:

The answer to your question concerning the SH4 effects for SH3 mod is most definitely "NO." It is not fully compatible with GWX and given the right circumstances may even cause CTD's when elements that are called on by the engine and/or the GWX mod are not found within the SH4 effects for SH3 mod.

The impression that some users may give, that SH4 effects for SH3 is indeed compatible, is erroneous and based on temporary luck rather than knowledge.

Users may of course continue to use the SH4 effects for SH3 mod enabled over GWX against our advice, and do so at their own risk.

OK.
Here are the facts.
You can run the Sh4 to SH3 effects if you wish.
Just like I can put Aviation fuel in my Dodge Pickup truck.

Sooner or later?
POOF!
CTD, lost Career, saves corupted, etc, etc.
Then you whine that GWX is screwed!!

I know for FACT what will happen.
And before you ask,
YES!!
I tested knowing exactly where and when this would happen.

I can reproduce it on demand!!

I say,
Roll the dice!!
But don't come crying when the DoDo hits the fan!!

If RB wants to fix HIS mod?
More power to him.
I offered to assist him and THAT is posted!
For someone who claimed to be so
"For the People"?
Where are you now?

SH4 SUX!
