Bodyslide mesh doesn't match ingame

[NachoTaco]

Hello everyone,

I'm having some troubles with making 3BBB compatible outfits with belly node. I was converting farmclothes01 from vanilla game, and after copying bones, masking body textures (zap sliders) and doing necessary adjustments, the outfit looks good enough in Bodyslide preview window as shown:

With pregnancy slider maxed in Bodyslide

However when I build meshes and test it ingame, the outfit doesnt remotely match what it looks like in Bodyslide. (Testing pregnancy)

Any help would be appreciated. I am using 3BBB body, HDT + CBPC and Hentai Pregnancy. Thanks in advance
