for info, by default, exporting from blender, there is an option Root Prim set to /root (when I keep this option, in UE, I'll have only one actor Root, showing in outliner)
Hmm ok ok, I’ll play with the different parameters this weekend, to be honest I just leave the default and only use this workflow if the blender file with materials is given to me. If I start from scratch, I prefer fbx because I’ve got a library of assets in that format and is easier for me to just drop them in the scene.
I usually turn off root (delete the text), so my objects don’t have an extra parent inside UE. Just for personal preference. Also, I noticed that emissive materials do not transfer over from blender to unreal engine for me. I have to re-create those in unreal
I’m working on a client’s project using this method and what I’ve been doing is not doing the final import until the client makes up his mind, so I’ve been just using the usd stage and refresh each time there’s a change. I’ll keep testing workarounds and show what works for my workflow on the next video.
Thanks for the walkthrough Miguel! Very cool to see the ins and outs of this system. Is there a reference for your lumen glass material that you could share? I'm currently getting bizarre reflections/refractions of my scene and the sky in my ceiling-mounted windows and having difficulty finding a guide online for this architectural-type glass. Cheers!
Hi @tovermoran4360 thank you for watching the video 🙏 you can download the template from my video updating our archviz template, in there you’ll find the glass material I use for my archviz projects. In the video I’m working now, I’ll show how to make a simple glass for windows and doors and some tips and tricks to avoid those refraction issues.

Hi Miguel, great tips - I follow your tutorial and everything works great - but do you have any ways to enable collision for this USD type format ? Thank you
Thank you Tam! If you’re bringing collisions from your modelling software, you should have a tick for importing collisions when doing the final import. In my case I like to work with simple box collisions.
Is that the one from GitHub? By Andres Botero? I haven’t tried it to be honest, but it’s not an official one by Epic like the 3DsMax/Revit/Sketchup ones, that’s what I meant in the video. But thank you for sharing!
Because the usd stage editor allows you to be working on the model and make any adjustments to your models quickly. Once all changes are made and you are happy with the look of the model, then import it into your content browser. If you import the model and you want to make some changes, then it becomes trickier or might crash the engine (this feature is still in beta) hence I recommend using the Stage Editor as a temporary bridge to work on the changes and then import it at the end. It’s important to import them so you don’t have issues when building your game. I hope it makes sense.
Yeah I find it great when the scene is complete in Blender and then exported it to unreal, but when you start adding stuff or doing changes, sometimes it messes up.
After the final import, what is the best method of updating if there is a big change in blender? Would you recommend dividing the scene into several USDs to avoid too much rework?
Hi Graham, if I were to use this method and had to do a big change in Blender, I’d prefer to create a new level and import the updated USD onto that level. Personally I prefer to use FBX and I only use this method if the blender file has been given to me with all its textures and materials.
Simply export a new USD from Blender, import to UE, and delete the old meshes from UE. A better approach is to stage the USD from Blender to UE, check everything to make sure it’s good, then import only when all looks good. However, for big changes later, you’ll need to reimport and delete the old meshes.
Hi! Please try to export and import a simple cube and see if still happens. Also, please check if you moved files forums.unrealengine.com/t/bad-meshdescription-causing-crash/1199440/5 or I also read that exporting the assets again and reimporting them into unreal will solve the issue.
@@mdandrade yes I tried with a cube and haven't move any files, sometimes it crashes sometimes it don't I can't seem to get a regular pattern though, BTW I'm using blender to export and perforce as revision control
hey, i want to know what will happen with pivot points. will It be according to blender? i mean if i put the pivot point of individual mesh on the bottom in blender, is it going to be the same in unreal engine?
I've try exporting USD with blender 3.6 and 4.0, and have an error : missing plugin . don't know why it's working for some people and not for others (I'm on windows)
That’s strange, to be honest it never happened to me nor I paid attention to the extension of the file. Try with the 4.1 version to see if works. Also, try to export it to desktop.
after some tries, I've found that exporting on our server was the problem. If I export in FBX in the same location , all is good, but if I try USD, I have the plug... error
18:48 - Number one pet peeve of mine: when people don't model based on real world units. It's like they don't even care. This is actually really shameful for an _architect_ to make such a rookie mistake. Shame on _Architecture Topics_ for not using proper units!
Oh don't be harsh, it's the unit conversion and I just wanted to show what happens when projects' units are not sorted/converted. It's good to show when situations like this happens.
build in blender render in unreal, seems a game changer thank you
And both free, we’re so lucky for their approach in that regard.
Life saver! I used to use gltf but in unreal 5 datasmith doesn't support it anymore, this fixed my issue, thanks
I’m glad it was helpful! 😁

Hi! Does this happen with any mesh? Try to export a simple box. Also, which version of Blender are you using? Does it happen on all recent versions?

why do we need to import meshes at the end if all meshes are already in the scene?

This option stage usd did not appear to me in unreal I activated the plugin but in the virtual this option did not appear😢😢😢😢
Click on Window, and look for USD Stage Editor, I think it's different in version 5.4
After deleting the parent material, the material window disappeared in the mesh imported into usd. How can I restore it?
Hi @Hobijak I think you'll need to re-import the USD and then delete the duplicate meshes. You'll have your master material back.
Thats great! TY a lot!!!
Blender USD import is still beta. Fails to import blender camera animation it sucks … wait few more years till they fix the stupid plugin 😂

@@mdandrade In saying this would you rather put the scene together in Unreal Engine then Blender? " I prefer to use FBX "
@helix8847 indeed, that way I can manage my assets library much better.

That’s a shame, I think I’ve exported skeletal meshes maybe a couple of times and was ok so far but I mainly work with static meshes.

Yes, it should respect the pivot point you had in Blender.
