Punk Fox Avatar for VRChat with Weight Gain and other kink systems · By
The timing depends on the size of the internals, but broadly speaking, you'll accumulate weight constantly while someone is inside. The weight gain speed is about equivalent to a round of food-digestion (4 pieces of food, or 2 slices of garlic bread) every 145-220 seconds, depending on the prey's size.
It's not fast, but it's enough to make a noticeable difference when someone stays in there a little while.
Eating food and rubbing the belly doesn't change the vore digestion, but you'll also gain weight from the food you eat- the feeding and vore weight gain systems can both work at the same time.
Also to be clear, there's no concrete "end point" to the digestion- it just lasts until you decide to spit the prey out, or they decide to hop out of the chair. If you want to play with the sentient fat/ ghost hands system, the prey can just change into the ghost hands avatar and hop out whenever the two of you feel like it's been long enough.
I'm afraid i don't currently have plans to do so. To be honest, the flat chest blendshape on the body got left in there from early testing, it wasn't an intended feature in the published version. My sense from working with it was that I wasn't satisfied with the flat chest for a "masculine" option- the shading and topology still felt like breasts, and the breasts returned as soon as any level of weight gain or feeding blendshapes were applied. So I abandoned the option and committed to doing strictly feminine shapes.
That said, better support for flat chest/ masculine shapes is one of the more popular requests I've gotten, so it's on my radar as something that a lot of people would like, and I might revisit it down the line.
Not a silly question at all, that sounds like unintended behavior. The .psd files should have a similar lightness to the .png files of the exported textures, so yeah, I'd try messing with adjustments until you can get similar results.
I wonder if the color differences might be your image editing software encountering some kind of version or setting mismatch with the .psd files- I haven't been able to test them myself in photoshop, but when i open them in krita it displays similar overall lightness to the exported .pngs.
I'm glad you've been finding the file layout easy to work with, I hope you can get the results you're going for!
It must be a software thing then. That's bizarre! I've attached a comparison between Krita (left) and Clip Studio Paint (right) and it's literally night and day. Both versions (IronRust & Firefade) are the exact files are from the most recent update. I don't think there's anything you can do on your end, since the files aren't broken, it's just CSP I guess? Wild. 
It's not very quest compatible, I'm afraid. The weight gain and vore systems use a lot of features like custom shaders, constraints, and audio sources that I think are completely incompatible with quest in standalone mode. Making a quest compatible system would require pretty significant alterations to the basic gameplay and functionality.
