Thank you soo much . Going with you.

Thank you again. I notice you didn't add DisplacementGrid, so my previews looked a bit different, but they still matched the written tutorial.

Hi Jourverse, im very excited about your tutorial had some weird problems at 22:00 but it was possible to rebuild some user exposed parameters and it was fixed.

You may have some mistakes. In your FX_OceanWater_SetRenderTargets, you should check your RT_PixelAttribsB_Casc0 and Casc3 module input's type, it is Render Target 2D type. Or you might forgot to add RT_PixelAttribsB_Casc0 and Casc3 (USER) in your user parameters of your FX_OceanWater or you added but wrong type. If you can't find the error, you can always download the finish project: drive.google.com/file/d/1IqdZL2nC5cH1M_l-xp6NWJVhBwmNXvOv/view.

Hello! Does anyone know how to unlock the "Set Num Cells" node?(6:10) My editor doesn't even show the Grid 2d collection category. I've tried enabling the niagara fluids plugin but to no avail.

Drag from FFTGrid and search for Set Num Cells. This node is in this FFTGrid.

@@jourverse I tried, it doesn't work, I'm guessing my installed files are broken in some way, I am even missing the grid 2d presets when I create a new niagara system
