In the Rendering module we will be able to establish visualization options for the viewport, since Flipbooks can be made, this is useful to make previous previews and to see the fluidity and final speed that our fluid is acquiring with the different settings, so that at the end we can use the last rendering section.
In the Rendering section we can finally configure how the final result of our scene will be, being able to generate videos or image sequences as we need the final material.
If we select Cycles it will try to set it to make use of the GPU.
In the World section we can add a new HDRI map quickly with only 3 clicks. It is important to choose a good HDRI so that our fluids look as good as possible in render.
In the Open button we can select the image we want to use for our scene.
We can also decide whether to show the background texture or to see a solid black color, or any other color, without altering the HDRI lighting.
