Wireframe on shaded, how? Jan. 18, 2018, 9:45 p.m.

anti aliasing are in the display settings, scene tab.

you can set wireframe over shaded from the display drop down above the viewport.

(this screencap looks crunchy due to gif resizing, the viewport looks buttery smooth).

For loops and timeshift Jan. 10, 2018, 6:41 p.m.

I can timeshift things in a for loop if its in ‘by count’ mode, but not in the other modes.

Either I'm missing a trick, or there's Reasons that I don't fully understand. Anyone have some insight here?

Adding new packed prims to an RBD sim Jan. 6, 2018, 7:12 a.m.

Here's a fix, feels like some optimisations could be made to the rest of the setup, but I only had the energy to tackle this much at this hour.

You can use a pop source to feed geo to rbd, much easier for this sort of thing. More info here:

For this to work in your case, in sops the shavings should only exist on the frame they're created. I made a wrangle that looks at the previous frame, and if the piece exists there, remove it.

In practice, it didn't work. A closer look revealed that the names are jumping all over the place every frame (look at the split node that should be isolating piece2, it acts crazy).

To fix I had to insert a little network above the one I just made. It freezes on the last frame of your shavings, so the names are definitely consistent, and looks at the distance to the nearest packed prim in the animation sequence. If the distnce is within a very small range, keep it, otherwise delete it.

The dopnet itself is pretty straightforward.
