VaM 1.x Can you exclude penis size changes when replacing male characters?

Nope.
A morph is a morph, it's agnostic in a way that, if not tagged or not categorized properly, you can't tell what it does. A morph called "Uber noice" could be a penis morph or anything else. Which, prevents to know exactly what to exclude unless you'd have a database of that information.

On top of that :

• You'd need a plugin handling that (and good luck coding that :x)
• You'd need VAM to be able to load appearances without specific morphs (which is not the case)

All and all this is why I never added male customization in scenes. Female have a 95% chance to have their genitals somewhat at the same place. Male on the other hand, even if it's alway at the same spot, length, diameter is basically never good. Which would end up breaking the scene pretty much all the time.

Save the character preset with the penis as the default morph always. Resize when needed.

Hi my plugin (RealisticErection) offers a way to load a person atom's previous penis morphs before loading the plugin. This is intended to restore an appearance preset's penis morphs. I think this could be used in your case.

1. Before loading your appearance preset over the existing atom in the scene, add the RealisticErection plugin, click on "Restore Previous Morph Config" (in the Morphs -> Reset & Restore tab). From now on, the plugin controls a lot of penis morphs (not all though).
2. Now load your appearance preset on the character with the RealisticErection plugin. The plugin will keep the penis morphs.

Let me know if this works please. Its intended for this purpose.
