I was going to do some different photography today, but I had an idea for the water drops that I wanted to try.
This is not the result of that, since once again I could not quite achieve what I wanted, but I will get there soon.
So here is a normal collision, but this time with glycerin added to the falling drops, which does seem to give a better spread to the collision when they are square on. Liked this one because the red is so deep, but also have some from earlier in the session with a more pink tone that I may upload some time.
I did also play with a couple of other variables. The exact effect of those I am not yet sure if they were positive or negative, but still all form part of the knowledge base for these.
