Lag intersection problem.

[mightcouldb1]

Hello all,

I have created an intersection between an object and a moving object. The moving object pushes the surface up to give the appearance that it is coming out of the ground. I like the effect, but since I am using a bounding source to group points that are soft transformed, as a point leaves the group, I get a popping effect in my transformation.

I wanted to use a lag CHOP to smooth the effect of the points leaving the group instead of them changing so abruptly. I thought that I'd have to use the animated method instead of static method in my geometry CHOP but the cook time becomes ridiculous and I get odd results. There is a switch at the bottom of the network to see before and after the chops effect. Any help is much appreciated!

Thanks,

Jason

I'm attaching an video of what I've described above. Note the popping and abrupt changes on the ground geometry.

you can use magnet SOP to achieve that effect

Ah thanks anim! For some reason I was getting weird transformations when using the magnet SOP. I see that you turned off a few parameters in the copy SOP and that seemed to do it for me.

I am still interested in finding how to make those points lag if anyone can help me out with that.

here is lag version

you need to use geometry chop in animated mode

but as soon as it caches the curves, you can lock it down, it's like the pointcache

then you can modify the channels (lag) and apply to object

thank you so much!
