Morning/Afternoon/Evening So, before this happens, I've been adding and merging and decreasing/deleting outfit mesh twice. But on the third one, I was going to add the wing(it was one packed with the armor, but the armor and the wing is in different shape) and I deleted the outfit(body outfit) and left the wing be attached Now, what I don't understand yet, this time when I add it, I didn't redo the whole thing. I just open CBBE body as reference, add the outfit, conform selected, conform all, save project, then build it through bodyslide. Materials are loaded(also I added a glowmap to it, although the wing doesn't seem to have spec texture and the armor came from Skyrim mod, which someone have converted to FO4 already) In-game, the mesh, material, texture loaded. But not for long. It only last 5-10 second then the game decided to ctd. I did a fix by removing the wing from nifskope, it fixed it. So my suspicion is on the wing, but I can't actually tell what's making the wing to be the cause of ctd What I haven't tried: 1. Removing the glowmap to see if it was the cause 2. Texture for _s.dds doesn't exist to this armor 3. This one is clueless... Opening nifskope to check if the nodes are causing it. But then again, I'm clueless on that part
