VDM brush creation

[Jon_Lendrum]

Hi, I was wondering whether you can create VDM brushes from meshes that have already been made rather than sculpting from scratch? I use a lot of scan data that is approved sculpts/ characters. I would like to basically use these scans to create ears, noses etc that are approved shapes from scans rather than having to re sculpt the shapes because I would then have to get approval on them again. Is there any way of merging a mesh down to the plane to create a VDM brush or is the only option to create IMM and dynamesh them in ?

My plan was to just use the plane to intersect or trim the scan using the plane, or something like that. I’m very new to zbrush as you can tell. Any help would be amazing,

Cheers

Jon

Hi Jon.

I don’t believe you can change the topology of the grid during VDM creation ( I welcome correction). The brush has to be sculpted from that grid. Furthermore the VDM should be kept to low-medium poly which may reduce detail on your imported meshes, and may distort significantly anyway depending on the underlying target surface if shape fidelity is a concern.

For these reasons, IMM + Dynamesh fusion (or Live Boolean situationally) is probably the way to go for inserting a prominent feature here and there. VDM would be for simple non-critical shapes that you are going to be repeating many times.

That’s what I was thinking, thanks for your reply

Why wouldn’t you want to only use IMM than?
