To finish our chapter on integration with animation, we'll look at painting cache…weights. This is a really interesting idea.…We can have more than one cache per object, and we can paint where we want a…particular cache to have effect.…In this scene, I've got a scarf that's got two caches on it already. Just…carried that over from the previous exercise. There's a cache that has wind, and…a cache that has no wind.…If I select it, and go to the Attribute Editor, Control+A, we can look through these…tabs here, and here it is: cacheBlend1.…
And you'll see they're both up at full strength, with no keyframes on them. And I…know that, of course, because these fields are in white, indicating there is no…incoming connection.…Now we want to open up this tool in the nCache menu, Paint Cache Weights Tool,…and we need to go into the Option box to get those tool options up.…So we've got our caches listed up here. We've got WindCache1, and noWindCache1.…Currently, they both have full influence, and I know that because they're both…
