3ds max 2020 tutorials Scene Layout - Referencing scenes with Xref objects But remember we added these two Xrefs if we go into here their combined size is almost 25 megabytes. But the impact on the disk here was negligible. We did not actually add anything to our disk storage and if we want to we can unload those just as easily. We can go back to that window, file, reference, Xref objects select one of them and you'll know it's selected if you can see the entities listed down here. And we can simply click the X button to remove that record. Are we sure we want to do this? Yes, all right that's the basics of working with Xrefs. You may encounter issues if you make changes to the Xref file. Those changes will not be recognized when you load your master scene. In other words if I went into plant house O, 6 and made changes and then came back to this master scene those changes would not be visible. And that's a very, very strange effect because you would expect that if it's merely making a link that if you changed the contents of that link that will ripple through to here. But in fact that is not the case. So just before warned, if you do need to make changes to your Xrefs, it very important actually that you go in here and actually remove the Xref record. Actually delete it. Then you can make changes to that Xref file then come back into this master scene file and re-reference it. And that's really the only way to make sure that any changes will be updated. There is a button here that's labeled update but frankly it doesn't work, so I wouldn't trust it. So that's the basics of working with Xrefs in 3ds max and that completes our chapter on scene layout.
