Here is my first morphable model. Its a Beaker glass and here is a video demonstating it.
Now I am posting some images that demonstrates how I created and animated them.
This one shows how to make an animatable Beaker. How many Fills need to be added depends on how it needs to work.
To completely empty a Beaker in one go only needs 1 Fill. But like I have done in my video I use the white one to fill 4 other Beakers.
Getting the waters to flow properly in that way doesn't work well with only 1 Fill and that's why I added 5.
If you buy this you will understand what I am saying as you start using them.
By the way, I loaded each of them separately and joined them so I can then move and scale them to whatever size I want them as.

Here Is how I made the 4 smaller Beakers. The beakers are actually the same size. There are 2 just so it was easy for me to apply the send image for the smaller one. As said earlier. Need to load and join the models need for the animation we need to do with them. Then they can be scalled to whatever size is needed.

Here I am showing how I set the colors of the waters in the Beakers. Obviously there are lots of ways to texture them other than what I am showing here.
I added 2 10Fill's to each of them so their colors would change as I loaded the white water into them

Another demo of setting the colors

Here I am showing the morph settings in the Fill's and what they are used for different animations of them depending on what is happening with the Beaker as the character is working with it

This image demonstrates the water flowing out of one of the Beakers and falling into another.
It is kept as a seperate image and just hidden, moved and showed depending on what is happening as the character works with them.
I orriginally had it as part of the Fill's but it was too hard to stop it rotating as the Beaker gets rotated. Thats why I made it as a seperate model
