Does anybody know how that wash effect to the sides of the ships is created, that is the cause of the problem and the file name would be a good place to start if anyone knows.
Thanks for your help Erg - it has not solved the problem, but nice to see what you are doing and there are things in there I will try.
I don't know RadPig. I've seen individual mods that are not rendered well with certain graphics settings. It's rare, but it does happen.
Sorry guys, different time zones, just got up and picked up on your replies, will have a look at hat later but one thing I noticed last night was if you look at that side wave effect it comes in 3 zones, one just after the bow wave, one in the middle of the ship and one towards the back. That's how it works on all models I think, except on the 2 tankers above where the forward one is about 3 mts ahead of the bows and the middle one appears to be almost on top of the rear wave effect, big gap in between.
I do not know how this works but assume it is something to do with the 2 models, a water mesh file or something is corrupted or not placed correctly, it looks ahead of where it should be on the model.
