Ship trail cutted at render time

[motik]

Hallo, our ship trail get cutted at render time, although the foam particles are visible in the preview, and outside life param is set to 20. We are running phoenixFD_adv_31200_max2019_vray4_x64.
Plese give us some help, thank you!

Hello,

Do you have a closing geometry under the ocean? If you don't, particles under water will not render correctly inside the material's fog because V-Ray needs a closed volume where the fog resides. Since the ocean is just an open sheet of geometry, it needs to be capped off, by using e.g. a vrayplane (we updated the ocean toolbar preset with a v-ray plane as well).

Thank you Zhekov, adding the vray plane solved the issue. Thanks a lot and have a great day!
