Hi everyone. First of all I'm creating this thread as I couldn't find an aswer for this "issue". Please redirect me if I'm wrong.  Well, here's my last creation, a Titan set from Destiny game. Some edges of the mesh get transparent as can be seen on top of the head or in it's eye hole (these yellow lines are seen as edges are transparent and shows that yellow part that's behind). It may be I'm doing something wrong while modeling on blender or anything else. However I could give it another coating, like adding a black plane, but I'd like to know why is this happening to solve it for future proyects. If this photo isn't clear enough tell me and I'll take another screenshot. Also, I'm spanish so please forgive me if my english is too bad. Thank you! |

Just a suggestion, did you try flipping the normal for the transparent bits(that you don't want transparent)?

It's hard to see from the size of your pic what is going. Also, is this a CAS or Object creation?. Something like this was reported while back with some objects cloned. I've fixed some of my using peacemaker's tutorial HERE. If this doesn't solve it please share the .package and .blend file. |

It is hard to see exactly what us going on here, but i think I know the issue. If it is what I think it is, its actually a graphics card problem which I experience with my GTX970 (common issue with higher-end nVidia cards when playing TS4). You can either fix your entire game for this issue with this tutorial but its quite advanced and you need to use a third party program. The other way i fix it in a similar manner to my glass tutorial which is go into blender and edit mode. Select the entire mesh and press crtl+T to triangulate (this is very important). Next make sure any edge split modifier is applied (if used) or that your mesh has all its hard edges in place. With the entire mesh still selected, press P then on the menu select "by loose parts". This separated all joined vertices into separate groups. To me, this works very much like assigning smoothing groups. Press tab to exit edit mode, then ensuring all groups are still selected and you active group is still selected (light orange and all other groups are dark orange) press crtl+J to merge them together. Import back into s4s and test ingame. Note, this technique works best on objects with at least a few split edges to get a few groups when separating. It sucks for things like fully smooth spheres. Hopefully that solves the issue. However, if it doesn't, could you post a bigger picture so we can see exactly what is going on? |

Thank you everyone. Sorry for that low resolution picture, here you have this one that I've just taken.  I hope it makes it clear. It's a CAS item as you can see here. I've given a look to those tutorials you've linked, and they don't solve this. Even so, thanks! Then I tried what peacemaker told me to do (separate and re-join the mesh) and this is what happened.  Now this happens on the opposite part of the mesh, it was at the top of the head before and now it's at jaw. I'll try a few more things. Thanks again to all of you and sorry if I'm making any trouble or time wasting. |

 Just a few minutes after the last post... I've tried what I said and it solved the problem completely. I selected the jaw zone, everything that had those "transparent edges" and did what peacemaker said, only with this part. This works as a provisional solution but it would be nice to know what causes this. The solution would be to select ONLY the part of the mesh that shows this error, separate it with Ctrl+P and "by loose parts" and re-joining them later, as peacemaker said. However this will help to anyone who has the same problem (if they find this site...). Many thanks to all of you for your help, specially to peacemaker , and if anyone is interested on this content please tell me, I've no trouble on sharing my creations. (I won't delete my last post, unless someone tells me to do it, so everyone can know clearly what's this thread about) |

I generally do the whole mesh as a precaution incase I didn't see an area that had the issue prior. Even EA's content does it so its not really a mesh issue, but actually an anti-aliasing issue with thenVidia cards when playing TS4. the tutorial by ivo-sims applying the antialiasing fix. As to the exact reason why, I am not sure but my guess is because blender doesn't support smoothing group functionality which seems to attribute to the issue. Good to know you solved the issue  |
