Inside collision new pyro solver (18.0)

[bxz4]

 

Hi,

Anyone know how to create this effects with the new pyro solver (geometry node)?

On the static Object you had to click on "invert sign" but I can't find that on the new solver

I just started Houdini sorry if my question may seem stupid

Thanks all

Maybe writing this in a volume wrangle could work: @surface *= -1;
