hi i’ve got a probrem with my project every time that I render my liquid sim the bubbles and liquid sim are not appearing in the render
That is normal.
By default, particles rendering is set to Halos.
That is a render type, only supported by OpenGL render, now.
That was the norm to render particles, in old Blender Internal that was removed.
In particles tab, you have to change that from Halos to Object. And in Object subpanel, you have to indicate an object like a sphere, that will be duplicated at each particle position.
And you have to give a transparent material to that sphere.
