Coordinate Method: Grid - Artifacts

[kurt-harriman]

Hi guys,
When I apply texture to opacity on dynamic fluids, and switch Coordinate Method to Grid, I receive smearing lines coming along the fluid motion. I changed the speed all possible ways, play with texture but it's still appear. Any Ideas ?
Thanks . (sorry cant post the picture)

is it also in the render ? it happen often that the fluids look weird in the hardware viewport.

it can be a cache problem, if you fluid is cached, it don't understand your methode change

if not, well, crewate an new fluid with all your parameters the same, just be sure having the good method grid before doing something
it should be all right... if not.... something wrong in your transparency texture or somewhere else ...

cheers

it defenetely because of texture, it just bend because of fluid swirls, but this bending looks very unnatural for smoke simulation for example . Maybe there is some tricks in fluid texture when I put it on opacity. In maya documentation they mention about smearing texture if the Grid speed is hi, but the main question what to do, if its happened . Any ideas. Thanks

Well, i would try to change few parameters in the texture to see if there is a point where it stop to create problems.
Maybe increase a bit the fluid resolution.

In fact, just try to twick little things to see if you can get rid of the prob.. i could see fluid opacity curve offset, texture resolution
Have you reset the cache ?

Check only the render, i don't really trust the viewport

hope that will fix it
