RealFlow Official Forum

I am running an ocean sim in realwave....everything looks fine using RF geometry...a capsule or a sphere

I size the capsule similar to a low rez boat OBJ I import....get the weight just right and object interaction strength...

The when I use the imported geo my water sim has crazy errors and spikes...instead of the smooth ripples I was getting from the capsule
The spikes and craters appear immediately when the boat touches the water...sometimes I will get a sharp little spike 5-10 meters from the boat just 1 frame after it touches down

The boat was just a few hundred poly's....I tried just a shell and using the open method....and the regular closed geo method...
I increased minimum substeps to 100, and reduced poly size to 0.05....

Nothing made a difference....I spent maybe 6-8 hours tweaking either the model or the object interaction settings with no difference...

I can get exactly what I want with realflow geometry....but not with imported geo

anything I am missing here...as far as best practices for realwave and imported GEO?

Hello,

could you try to deactivate the choppiness and let me know if it is working now?. There is a bug when using the choppiness in realwave due to it is affecting the interaction between objects and RW.

I kinda worked it out before you answered....it seemed to be ok without any wave modifiers present....once a wave was present it went crazy.....so ya choppiness could be it

I changed statistical spectrum scale to repeat U,V @ 1.25 and some other changes and it eventually seemed to go away....

Thanks for the info. We'll check out that.
