That's worked!ThanksJuM wrote:go to material editor window there is a "Material" button next to "Modes" button. Click on it then it drops down. There should be a line Highlight assets in ATS dialog or something like that. Click on it and new window going to appear. Find the external file which is missing and relocate it with right click/set path. Press "OK" then close the ATS dialog window. Thats it.
