Hi, I’m creating hair strand assets with multiple groups (0, 1, and 2) and I want to be able to control the card generation for each group but these options seem greyed out or just unavailable in the generator.
If I turn off ‘Generate Geometry for All Groups’ nothing new becomes editable.
I can’t “add” a new Setting Group at the bottom so I’m confused as to what’s happening there? It seems like you should be able to add multiple setting groups and have them set for each groom group ID, or am I reading it wrong?
was there ever a solution to this? I’m at 5.7.2 and the Generate for Groom Group is still greyed out. I can only ever generate for everything at once, or just Group 0
You need “groom_group_cards_id” attributes in your groom (for whatever reason) then they would be visible automatically at the bottom. If you only see [ ] then you miss that attributes.
If you have those attributes then you can click on advanced and remove unwanted groups for generation. I’ve added that attributes to the Blender exporter i use (just copy of the group name) and it works. But the hair card groups are still experimental in UE at least. You can generate a few LODs for group 0 (e.g. top) and seperate the texture atlas for that group. Only the strands of that group are used for generation which is fine if you simulate one group but not another (so far so good). But as soon as you pick the second group (e.g. bangs) it would overwrite the atlas of the previous group (top) if you are not very carefully (default is wrong) and don’t pick a different folder and even if you pick a separate folder then the following groups are still somehow referencing to the first group. If you reimport the groom after a change in group 2 (and strands look completely different now on group 2) nothing would happen at generating group 2 again until you generate (completely different) group 0 again.
