Dataprep only has a "filter by volume"... but how do you know the volume of your objects in the dataprep window?
I can only see an "approx size" for the entire import, and even then, I have to manually multiply those three value together to get a volume.
It would be nice to get the volume directly in the interface, and also be able to select and isolate individual objects in the view.
(Also, if it will end up with a blueprint paradigm, and not stacks, it would be nice to see what rules affect what objects, like you can with the line highlights when pressing play.)

Datasmith Feature Requests

pauljohnson repliedI have recently been working with some very large Revit files. My workflow has been to break the model into 20 sectioned views in Revit and export them individually to Datasmith files. I have then created an editor utility that imports each view to a new streaming level. These can then be streamed in and out at runtime in UE4.
Unfortunately, each separate Datasmith file creates its own Geometry, Materials and Textures folder. This means that even though assets are actually shared between views, each brings its own copies.
It would be great to have a feature to allow multiple Datasmith files to share the same asset folders in unreal. On Datasmith import it could skip creating any duplicate assets and use the existing ones from the folder. This would both increase performance and make further data prep much easier.
As a bonus, it would be amazing if the Revit exporter could export multiple Revit views at once (perhaps a gui to select which views to export?)

frost-xyz repliedOriginally posted by roberteker View PostDataprep Commit seems to add everything back into the current level, which is annoying if you've made changes. Datasmith has an option to not respawn deleted actors, but Dataprep doesn't seem to have this?
Also, the result from the Dataprep Commit does not have the white balls on empty actors that the result from a straight Datasmith import has (which is preferrable actually, so I'd rather hope that when you drag a Datasmith scene into a level in the future the white balls will be hidden for it as well).

frost-xyz repliedAre there plans to improve the Python API reference, to match the more recent features of the Dataprep asset? Would be nice to have those in relative feature parity. As far as I can tell the more recent features of Dataprep aren't covered by the API: https://docs.unrealengine.com/en-US/...s&area=default.
Also speaking of the Dataprep asset, attempting to view Metadata to filter assets is nearly impossible through the Dataprep window—UI needs some adjustment.

david.gillespie repliedOriginally posted by goodchild31 View PostHi, I need to read PDF files in UE4.
A data of assets contain the path to the PDF file and I need to watch it in the viewport.
Maybe it's already possible but it seems no.
Is it possible now and how?
Thks.

What you say is true. However if you want to use models in Max, Revit, Sketchup etc format then you need to own these applications. Unreal won't import their native file/project formats.

roberteker repliedI would like Dataprep to have it's merge functionality work similar to HLODs:
Define a radius, and check if the total bounds of each sub-hierarchy (ie CAD assembly) can fit within that radius, and if so, merge those actors.Last edited by roberteker; 01-08-2020, 11:13 AM.

Unless I'm mistaken, Unreal Studio included Datasmith functionality was included in Unreal Studio which has been wrapped into 4.24. Someone please correct me if I am wrong here.

Unfortunately this is not the case. You need to have a valid license for these products and then use the Datasmith exporter to output a .udatasmith file that you can subsequently import into Unreal.
This is for licensing reasons I believe and is not likely to change.
There is no reason why Unreal shouldn't support .blend files natively as Unity does however....

roberteker repliedDataprep should have a box mapping UV unwrap node, with real-world units as input for the tiling (yes, I know you can achieve it with materials, but not everyone using Datasmith is a shader wizard).

Here is the link to the current status of supported software... Autodesk Alias Wire, Autodesk AutoCAD, Autodesk Inventor have direct import support while Autodesk 3DS MAX, Revit and VRED need the export plugin so requiring to own the software packages.
If that was a license issue with Autodesk.. why would they allow Epic Games to create native direct import code for Alias Wire, AutoCAD and Inventor files but stop them from doing the same with 3DS MAX, Revit and VRED ?
And there is direct import support for PTC Creo Pro/ENGINEER, Dassault Systèmes SolidWorks and CATIA V5 which are far from cheap software... it just doesn't make much sense that only some Autodesk packages would never get direct import support.

Datasmith does this - it's been added to 4.24.

david.gillespie repliedOriginally posted by DarkS474 View PostI still hope there soon will be full support for native Direct import of Autodesk 3DS Max, Revit, VRED and Trimble SketchUp Pro files, so that poor indie developers could convert/import paid assets/projects bought on other marketplaces directly into UE4 whenever FBX or other exchanging formats are missing as well as not having to deal with materials conversions for expensive renderers like V-Ray and so on.
(Merry Christmas)
