3ds max 2020 tutorials Scene Layout – Referencing scenes with Xref objects So external references are a way to minimize the disk footprint of a project. They also make it easier for you to do things like load and unload models. So that you can maybe save on memory or performance. So Xrefs are very handy and especially if you’re building large architectural scenes or environmental scenes you’re going to be working with Xrefs quite a lot. So I’ve got some plants that are relatively heavy models that is they have a lot of polygons. I’ve placed them into my current project in the scenes folder, in a custom subfolder that I created called Xrefs. So go into the Xrefs folder and I’ve got some plants here and we can see there are 13 megabytes and 12 megabytes.
3ds max 2020 tutorials Scene Layout – Referencing scenes with Xref objects Go back up to the scenes folder and here is my master scene. The one that I’m going to reference those files into. It’s O, 3, 10Xref. So I’ve already got that loaded in 3ds max. So let’s bring that up on the screen. And then I’ll just reference those plants in. And that’s done from the file menu, reference, Xref objects. And you want to choose Xref objects, it’s going to give you a lot more control. Xref scene is not really applicable in this situation. So I’m going to choose Xref objects and in the dialog I want to create a new reference. And that’s what this button is here. Create Xref record from file. Click on that button and then you may need to navigate, right now I’ve been taken directly to my Xrefs folder but you might be in your scenes folder. But I do recommend that the scene that you’re referencing should be somewhere inside your current scenes folder.

3ds max 2020 tutorials Scene Layout – Referencing scenes with Xref objects I’ve just put it in its own subfolder here. So I’ve got plant house O, 3. Select that and click open and it’s listed here and it also appears in the scene. It’s not actually selected even though it’s highlighted. So if I click off of it and click back on it. Then I see a list of all of the entities that are loaded in from that scene. In this list we’ll see three types of entities, objects materials and controllers. So the materials are imported if they exist and if we want to we can use those materials in our scene or we can override them.
3ds max 2020 tutorials Scene Layout – Referencing scenes with Xref objects Let’s load in another one. So click on the create Xref record from file button again and choose plant house O, 6 and click open. And now I’ve got two plants. I’ll close the Xref objects dialog, grab the move tool and we can position these. Now if they’re both selected we might need to deselect and re-select, there we go. So I’ve got those two plants in there and they are referenced into this scene and I’m going to save the scene in the current state. So we can compare file sizes. I’ll go up to the file menu and choose save as O, 3, 0, 10Xref, finished. And click Save. Now let’s go back to Windows Explorer and investigate. Here’s O, 3, 10Xref, that was the file before we referenced anything in. And then below it we have the one we just created O, 3, 10Xref finished and it’s almost exactly the same size. 3ds max 2020 tutorials Scene Layout – Referencing scenes with Xref objects
