And here is the ending for the 2nd part. This one part of the animation is almost final, it will be improved at the polishing stage.
I've added little bumps to the main tentacle so it looks more alive and more... fluid? I'll later remake the material for this tentacle, something is wrong with the current material.
I`ll later try to add some physics to her body, so it would look a bit better. Can't guarantee that it will get to the final version.
Now it's time to start making 3rd part, the final one.
To be honest, I've mixed feelings about liquids and physics in animation. This is a very cheap way to improve any animation so that it looks, if not good, then god-like. Even the worst animation can become a decent one if you add some physics on thighs, ass, etc. Almost the same thing with liquids, but unlike physics on the body, they are a lot harder to setup (if you use built-in liquids in Blender). But worth mentioning that sometimes even the bad liquid simulation can improve a good-looking animation (looking at Sladdoska's animation with his Cobolt). In my opinion, it's better to leave the animation without any liquids instead of adding a weird-looking one.
And here is the other side of the coin, just as physics and fluids can improve bad animation, they can enhance a good-looking animation and make it A LOT better (looking at Ruaidri 3d animations with liquids).
Thx to Ruaidri for the tips on adding liquids to the animation
