The release focuses heavily on visuals and material control. Key changes include a new Jake body skin, new normal and specular maps, plus support for PBR and Blinn materials. There are new material controls meant to give users more customization over how skin and surfaces render in-world. The HUD was redesigned and provides both light and dark themes.
Jake V4 adds practical fit and animation tweaks:
- Five foot shapes and five fingernail shapes.
- A toe cap option so toes don't poke through socks.
- An ankle lock and foot-height adjustments.
- An asymmetric left arm option and a hand animation cycle added to Bento hand poses.
- HD mesh nipples with flat, normal, and hard options, plus color choices.
The blogger highlighted the hands as no longer appearing robotic, the improved skin with realistic elements, and optional nail polish for cosmetics.
Compatibility with heads, shapes, and older clothes The author used the Jake V4 body together with a LeLUTKA Rune head and a Tivoli inc Lawson shape. A new neck blend makes Jake V4 work with LeLUTKA Rune Hinti skin. The post confirms Jake V4 works with older clothing and items, so existing wardrobes remain usable.
Jake V4 increases compatibility with Belleza's Gen.X ecosystem. It supports Gen.X nail appliers and material appliers. New add-ons are available: a Gen.X Feet add-on and a Female Neck add-on for compatibility with standard female heads.
A new Auto Hide ON/OFF toggle lets users choose whether automatic alpha cuts apply for compatible clothing. That gives more control when mixing mesh bodies with fitted mesh or system clothing.
The blogger wore Jake Skin Soft Tone 08, the Cole Tank and Jeans, and kept the Tivoli shape, LeLUTKA Rune head, and Volkstone Austin facial hair. Boots exist for the body, but the blogger deliberately showed the bare skin close-up. The upgrade was tested on the remodelled Pususaari sim.
- If you already own Jake V3: use the Belleza redeliver button to get V4.
- If you mix heads and bodies: check the new neck blend and the Female Neck add-on for fit with standard heads.
- If you use appliers or Gen.X parts: confirm nail and material applier compatibility.
Jake V4 is an incremental but practical upgrade focused on visuals, fit, and compatibility. The changes make the body easier to blend with existing heads and clothing while offering more material control and cosmetic options like nail polish and nipple choices.
