I packed and saved the textures. however, I may have to re-introduce some colors even on my own computer (it may not show the same file name because I copied it again after coming from the service). That's why I made a folder on the portable hdd as a solution, I choose from here during the project and after the project is finished, I package it and save it in the folder where the project is located. Otherwise, I'll have to do this over and over again. but I have seen it in the projects shared by you and some of your users. For example, I downloaded the kitchen project of Mrs. Wish. but some of the materials were missing. sometimes when I select these libraries completely and throw them into another project, when I enter the library properties, it says idecad architecture is closed. So what I don't understand is why I'm having these problems so much, is it me or is there a glitch in my pc? I haven't had luck with the pc anyway. When idecad gives an error like this and reproduces the shutdown, I format it. I'm struggling again. but I couldn't have so many problems when I used windows 7 64 bit ultimate. I don't know if I will have a problem if it is home premium or ultimate.
