I'm having an issue with "bleed-through" problems with transparent meshes (glass), and objects with two mesh parts where one is supposed to always be visible and the second is meant to have recolors where it's possible to hide parts of the mesh via the texture, kind of like cutouts for leaves and such (it's a conversion from TS2, where this trick works fine).
Technically, it works, but the second mesh part keeps bleeding through and acting strange (something I'm familiar with from using the Blend setting in TS2, if anyone is familiar with those issues - but in TS2 this Blend setting can be disabled and another setting can be enabled to allow for visible/invisible alphas, for instance leaves and such).
The problem is especially annoying if the transparent item is combined with the alpha'd item (the one with glass has a slot, the other is a deco mesh). The issues only appear ingame.
In TS2 I could fix it by changing the mesh order (but this seems to be fine), or fix settings in the textures (which I did wherever possible) - but I have no clue how to fix this for TS4.
I'm also having some very annoying shadow issues. The items have "meshed" shadows instead of floor shadows, and these make very ugly blotches on walls and other items. Any tips on how to reduce those? It's probably half due to lowered settings, since it also happens with other objects.

If you've got pictures of these issues and your files that you can be share it would be a lot easier to offer help.

One of the files: simfileshare.net/download/1580410/ (there are 39 altogether, and I'd like to use the same trick later, so I really need to figure this one out)    The second mesh group has a bunch of "accessories" which can be added or removed with the texture (I think I used a plant for this item to get the cutout effect, but it's been almost a year so I can't quite remember). The same trick works fine for the original TS2 mesh. For TS2 I've seen this issue happen with the wrong texture settings, but there it's just an easy fix (turning off the blending on the alpha, instead only enabling cutout). I don't know much about how to edit texture settings in TS4, but I kinda hoped there was a similar fix... It's the second mesh group with the "accessories" where the mesh doesn't seem to make sense or seems to "jump" in front of the glass. particularly where they intersect with see-through items like glass. The problem kinda flickers in and out depending on viewing angle. There's also some weird shadows going on. I kinda solved this by only leaving the "skin" mesh in the shadow group, but it only reduced the shadows a little bit. I get ugly shadows everywhere, but it could be the graphic settings. While I'm at it, is there a way to convert from the meshed shadows to the flat ones without having to start over with a different mesh? |

Could you share an un-zipped package?
I'm trying to understand the picture. You are saying that in sims 2 the baby wouldn't have a hat on, and therefore it wouldn't poke through the glass?

www.simfileshare.net/download/1581631/(the earlier zipped version was packed with 7-zip) No, I'm saying the TS2 version works exactly like they're supposed to, but in TS4 the "accessory" part of them (hat, blanket, etc.) kind of bleed through anything made of glass, or become see-through when they're not supposed to. The body part seems to work fine, though. It's a mesh with 2 groups, the body on one and the "accessories" on another. I think the file perhaps explains better how it's supposed to work, because the issue isn't visible in S4S, only ingame. I think it may have something to do with the alpha settings. I want the "cut-out" function like leaves and such, but not the "blend/transparent" function like glass has because I think this may be what's causing problems.

^ Not really. Looks like it's more on transparency as in see-through materials and for outfits. Mine is a deco object and already set to some sort of transparency, but it's not behaving like I want it to when interacting with other items. Is there a tutorial that explains how different types of transparency, cut-outs and so on works for objects? Maybe one that explains the different types of shaders? I had a look at this one but it just shows how to switch from opaque to transparent textures, and the part of my mesh I wanted to edit didn't seem to have the same instances - but there's a lot of clicking and opening various tabs to do one simple edit, so it's a bit difficult to figure out where to edit things. (I'm new to the Warehouse tab in S4S, but I have made TS2 items for a very long while with SimPE, so it's more learning the interface thing, what's possible, and how to do what and where). |

I am a little confused, the baby is also an object right? the blanket and the hat too? if so you just need to enable alpha blending, just like the tutorial says, if you can share the package I can show you how to do it for your object

The package has already bee shared three posts above yours sigma1202 I took a look but I don't know enough to help. The baby and the clothing it wears are all a single object. There are two mesh groups. One for the baby which is set to Phong, and one for the clothing and accessory parts which is set to PhongAlpha so that they can be added or removed via swatch options with different alphas. When the baby is placed inside the hospital crib in the pictures, the game doesn't seem to know what should be rendered closer to the player; the baby accessories or the crib. |

Yup, that's the main problem. It's the "PhongAlpha" group that's causing problems. Anyone knows why it happens, or if there's a way to fix it?
I'm honestly not sure if it's the baby or the crib that's the problem. I think I used one of the deco objects with glass groups to make the crib (the jewelry bust in a glass display, or some such - it's been a while), so the settings for the crib are most likely similar to those.

I've had a look around, but still can't find anything useful. Does anyone have an idea how to fix the transparency issue?
