Struggling with Flex [3DS Max]

MyLittleWeirdFriend

Hello, im trying to create a scene where a boat travels across water using 3DS Max flex modifier. 

I have managed to get everything to look the way i like and i started to render, after it was done i notice that the Water pulsates and creates more waves after the boat has passed which i do not want. as you can see on the gif below, it pulsates 7 aditional times. 



I have no idea why this occurs and i have tried changing the parameters with no success, this is the best looking wave i managed to make.

i tried changing the sway from 0.1 to 1 which resulted in weak waves but still pulsating.

i tried to change the samples from 5 to 1 which resulted in this



(i am aware that there is better ways to do this and im planning to try and recreate this in houdini with water physics in the future, but now as i am so close to the finnish line with this project i would love to finnish it!) 



anyone who knows how the flex modifier works and what could be causing this?

Here you can find the project file, if you want to take a look at the set up. 

you might have to recache and resimulate the flex modifier to see the results. 

thanks in advance for your help and have a great day!

Second gif looks fine

Seriously though, did you resolve the issue, if not?

this might help:

I've only had passing experience with Flex, from memory think it was a mechanical sim for tank tracks or somthing but yeah, there are alternate methods nowadays that'll output better results with minimum hassle.

Didn't check the file, but it doesn't look like you have some pre-animation for the boat coming in. Looks like the "impact" from the boat being calculated at that point for the first time might cause those big circular ripples.

Thank you for your help! The video did help the main problem was that flex standard setting is to have the corners to weigh more then the middle. causing the effect to really only happen and remain at the beginning of the boats path!

I had previously missed to make every vertex weigh equally and it solved the issue for me. here is the result if you are curious - https://www.artstation.com/artwork/L2Kzev
