Hi! first post here. Starting with Houdini as well.

Im creating a scattering tool for Unreal using an HDA. I would like to know some recommendations for the following two questions.

Im using the mask_by_feature node to get the area i will scatter the geo onto, but i was wondering what kind of image processing nodes Houdini has to create more options to edit the mask. For example, is there like a “contract” selection node or something (as in PS)? so i can make the mask thinner.

I would like to know how we can be more specific in the scattering. For now, i think the node follows a uniform distribution algorithm, but i would like to for example, have more control over the scattering (im using the heightfield_scatter node).

Thanks.
