I'm working on a very large scale project and I want to try to make an object with Smoke Inflow but only from certain faces. How would I select or define those certain faces in Edit Mode?

Anand mbs is correct about selecting faces, but to use those selected faces in a Smoke Simulation, you need to do some more stuff.

Selecting The Faces

At the bottom of the 3D Viewport and while in Edit Mode, you can click a button that looks the following to switch into Face Select mode.

However, also while in Edit Mode, you can key Ctrl + Tab to open a pop-up menu like the following. You can then either click the bottom option (Face) or key 3 to have Blender automatically select the third option down.

Separating Faces

We're not quite done yet. RMB select the first face and then Shift + RMB select the rest that you want smoke to emit from. Key Shift + D to duplicate the faces. Key P to bring up the SeParation pop-up menu. It looks like the following. Key 1 or click on Selection to separate the faces from the original mesh.

Smoke Simulation

Tab back into Object Mode. Select the mesh that is made up of the separated faces. This will be your Inflow object. It is also probably wise to Parent the faces mesh to the original. Parenting will guarantee that the faces mesh follows the original during transforms. Select the faces mesh, then the original, then key Ctrl + P and either 2 or select Object (Keep Transform) from the resulting pop-up menu.

you can change the selection mode from the above option. 1) vertices, 2) edge, 3) face.

  • $\begingroup$ Your question doesn't provide enough information. If you want to set up those faces so you can select them easier, you can assign them to their own vertex group and then select that to get to them. $\endgroup$ Jun 2, 2016 at 11:29
  • $\begingroup$ Your answer talks about selecting faces, but not how to incorporate them in a Smoke Simulation. $\endgroup$

  • $\begingroup$ @ShadyPuck , at first I am sure that the smoke simulation was not mentioned. The question is edited $\endgroup$

  • $\begingroup$ @anandmbs You can check the editing history and see that it indeed was. $\endgroup$
