Hi if i select an emitter and click on create a mesh button in the toolbar.Im not able to see the polygon mesh for the fluid.. tel me whats my mistake and what should i be doing

There are usually a few reasons for this. If your sure it is attempting to mesh, perhaps you have set your polygon size too high?

u mean the scale of the scene..?? could u explain me in a more simpler way..

Sure. In your "Nodes" window, click on the mesh node. In it's parameters, you'll see the "Polygon size" attribute. The defaults to 0.0, which actually lets Realflow decide on the best polygon size (I think). However, my guess is that you might have set this too high? Try setting it to a smaller value.

However, this is a bit of a guess. There are many other reasons that it won't build a mesh!

Actually, I've just noticed that you specified you selected an emitter and hit the "Build meshes" button. Do you have any mesh objects in your scene? Hitting that button builds mesh objects, it doesn't put a mesh around a particle system for you. Sorry if this is obvious, but you meed to create a mesh object, then assign it the particle system that you want to build a mesh around (i.e. your emitter).

Cheers, Sam.

hi sam..
sorry am just a beginner.. its been only 2 days since i started learning real flow from the tutorials.. you have mentioned like "to create a mesh object, then assign it the particle system that you want to build a mesh around (i.e. your emitter)."

thank u so much

You can add a new mesh object just as you would add any other object to a scene (an emitter, a daemon, etc); There is button for it on the tool bar at the top, or right-click on a viewport, and got to Add > Mesh.

To assign your emitter to this mesh object, right-click the Mesh object in the "Nodes" window, and select "Insert fluids". Then select your emitter from the list!

... now try hitting the "Build meshes" button...

Sam.
