I investigated this problem and it come from mod file:

"data\Shaders\Wakes\ShipWakePS_SH5.fx"

As far as I understand this mod, in version 4.0 and probably since many previous versions, maybe even since ever (date of the file is: july 9, 2010), this ship wake modification was simply NEVER ACTIVE, because the file had the following INCORRECT NAME:

"ShipWakePS_SH5.fx.txt"

In mod 4.1 and 4.2 you have two files:

Still our "ShipWakePS_SH5.fx.txt" (dated july 9, 2010)
and a new one: ShipWakePS_SH5.fx

Something I have already mentionned twice, but as usually, Mister W_clear do not reacted to my attempt to help. :hmmm:

This is a mistake, it will adjust in 4.3, please delete this file。thanks！

Be kind and remember language barriers please .

Thanks Understand me。My English isvery poor .So I answer the question really tired, need GOOGLE translation, but basically to understand vague.

请 ACSoft理解，如果你会用中文问我问题，我一定会很详细的回答您。

Sober,

I have just realized some minutes ago, that W_clear had a language barriers problem. It is now 2 weeks I tried to communicate in private with him, to offer my collaboration, in order to more improve climate zones. But I was disapointed to receive very short negative answer or no answer at all.

As W_clear do not mention his country in his profile, I had no clues to guess this problem. This is why I asked to him yesterday, by private message, if he has this language problem, because I stated to suspect this.

I just received his answer a few minutes ago, that he confirm now in chinese here.

To W_clear:

W_clear, I am very sorry you have difficulties with English language. I would have loved to collaborate with you, in order to help you to improve your beautiful work.

W_clear，我很抱歉你有英语的难点。我也喜爱与你一起合作，以帮助你提高你的美丽的工作。 -


ACS

To all: use only simple / easy english and short sentences.
:03:

Simple and easy english: Thank You for this mod !

Also, thank you ACSoft for your patience and for correcting/helping on bugs, very much appreciated!

Thanks W Clear. Great work :yeah:

W clear, I also want to thank you. Your work is simply amazing!:yeah:

does v4.2 fix the wake problem? :06:

No, but the culprit seems to have been located.
It's probably the content in data\Shaders\Wakes.
Waiting for fix in 4.3.

As the man said:

Hi Mr TDW
This is a mistake.
I wanted to solve the problem of white foam. Wake and foam is to use the same parameters。But no solution, I really hope you can help me，Wake and environmental impact of the bubble are very strong, this has led to a bubble of infection when you set the other colors。:salute:

I do not know can you understand my Chinese English?:cry:

Is possible to decrease a shadow effect at bad weather?
Now the shadow looks like in a sunny day, but this is storm...
Storm -> no sun shafts / no sun light -> no shadow
