I finally made all my hairbases Omega compatible! They are available at the mainstore and on marketplace now.
The vendor images show them on Lelutka Bento Simone – please note, they apply on the tattoo layer on this head, so you need to tint the tattoo layer, NOT the hairbase layer! They also work nicely on all Catwa mesh heads and on LaQ Trinity.
For all other Omega compatible heads, please try the demos! Not all UV maps are exactly the same, so they might not look nice on every head.

I bought Tintable updo Hairbase II after having tried the demo for the same product. Only the demo worked like charm but not the bought product!
Hi Apmel, please contact me inworld so that I can help you! The bought product should work exactly like the demo, so please let me know what’s wrong!
