Flin x Kelly (animation) (Patreon)

Using the "butt jiggling" animation from the last post as a starting point, I made this new animation (for both Kelly and Samantha). As I've said, the two will recycle a lot of work from each other, which will really help me square away Kelly's content once I'm done with the Samantha sequence I'm working on.

Just as that last animation was the first-ever butt jiggle, this one is the first-ever ass grab (which also jiggles, which I like).

This is also the first time an animation with outlines has featured a "grab" of any sort. I mentioned in my last boob grab post how I've gone back to using 3D models to form the "flesh between fingers" bit, just with a separate mesh instead of Kelly's mesh.

However, I mentioned needing to still do some touch-up in Gimp in order to make sure it still draws outlines properly. I can't draw new outlines for every frame of an animation, so I needed Blender to handle it.

The PROBLEM is, Blender's outline rendering currently doesn't have a means of handling mesh intersections as a place to draw outlines, and the workaround solutions are pretty clunky (also, I don't necessarily want everywhere that meshes intersect to draw outlines).

My solution was basically to perform a Boolean operation on the "flesh mesh" (lol) that subtracted Flin's hand from it, creating a cutoff right at the intersection. Here, I'm pulling back a piece so you can see.

I needed to give the mesh a tiny bit of buffer room between it and the hand, but then it started drawing outlines nicely (I kind of ignored the area where the thumb is clipping into the flesh because it was coming out messy and I thought it looked fine without outlines). It isn't flawless every frame, but it doesn't need to be, and I think the result worked well for the animation.

Boolean operations, where you "add" or "subtract" meshes from each other, are generally avoided because they totally fuck up your topology. You can see in the above image, those little pieces have TONS of vertices dotting the outer perimeter where they had intersected with the hand. It's terrible. But, sometimes you can determine a situation where it's not going to matter in the long term and will save you a lot of time in the short term. It's worth it here.

Anyway, definitely going to do a boob-grab animation with outlines at some point as a result of this working.

Overall, things are going really well. I think I'm going to make one more Samantha animation (a mostly recycled version of an animation all the girls have), and then I'll patch up the rest of her sequence with a few CG's. Getting somewhere!
