Problem with Merge Actors and Textures

Hello. I’m trying to merge two objects with differents material and textures. I don’t know why, but there is some textures that doesn’t work well. It looks like in a box I have two different textures in both sides, and when I do the Merge… then is the same texture in both sides.

Thanks in advance.

我也遇到了这个问题 但是用另一台电脑却解决了这个问题 偶发性很强

确认了一下引擎就好了 可能是临时文件引起的 希望下个版本可以修改
