Ask : Rendering

Why is the render process so slow?

Make sure that your simulation has been  cached before you trigger the render process. Without cache files a frame has to be simulated and perhaps even meshed before it can be rendered.

If you did not cache the simulation and want to render a certain frame, let's say frame 90, the simulation will be performed from frame 0 to 90. Once the missing part is simulated, the render process will start.

I can't see particles when I render. Why?

Particles are nothing more than points without a dimension. In order to render them you have to connect the geometry you want to instance to the "Fluid" node.

Where are the meshes? I can't see them in my render. What's going on?

The creation of meshes is a separate process. If your scene does not contain a mesh node you have to add it, adjust its parameters and create the meshes for the entire simulation range. We recommend adjusting and simulating the particle part first and cache it. Then, in a second step, you adjust the meshes and cache them as well. This split workflow is by far more economic.
