Thanks i did all this but is was a waste of time as I wanted a 3d text domain object that blender would fill with liquid, however domains apparently have to be cuboids and simple so the program just crashed XD
You don’t control the shape of your fluid by the domain object, you use obstacle objects. Ensure to read the fluid documentation so you understand the difference between a shell and a volume. There are many threads on these forums discussing fluids and how to get then best out of them.
Also, where are blender boolean operations located. That help doc is from 2.6 and doesnt explain where to find them. Just what they are.
under the modifiers button (spanner icon) in the properties window. I’d suggest you start from the very basics to understand the window layout and how blender works before using fluids. In one of your other threads I’ve given links to varous help/tutorial sites, make use of them.
Or can blender no do anything with fluids and complex shapes at all?
Yes it can (but don’t expect miracles), but you need to know what you are doing, this is where you are tripping up. I suggest you do some initial research on how things work, then it will be clearer when you start setting up your fluid sim and how to get then best results
