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?

In order to see the particles in your render you have different options. You can

• connect the geometry you want to instancewith the "Fluid" node
• convert the fluid to →nParticles. Once converted to nParticles it is possible to use other third parties tools.

Everybody's talking about meshes, but 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.
