I started with datasmith, mainly because vray materials converted to UE, but only good thing is converting bump material, so I guess I can create all materials in UE still. When I import model from max to UE over datasmith everything is fine, but then when I import some missing model over FBX i have to scale it i think 10 times? So I guess I have to go again over datasmith for importing forgotten or missing models. Also I was experimenting with LOD (great stuff by the way) and datasmith doesn’t import LOD from max, just import group, so i guess i have to do it manually again (can somebody help me on this)? What do you think what is better pipeline 3ds to UE, what do you use, your thoughts and experience ?
Hi Kratos.
Have you tested the Datasmith workflow from 3ds Max on the new UE 4.20 Previews? 4.20 has a number of improvements over the 4.19 release, including better LOD support. See the below note from the 4.20 Preview announcement thread.
can you please tell me difference between 4.19 unreal studio and 4.20 unreal studio Preview? what this preview mean is that beta version ? also i still cant download unreal engine 4.20 ?
Any directions on where to find this neat little script ? Been playing with the samples for a few days for data prep and I have to say it works quite well (when you succeed in getting through the command window docs 
)
4.19 and 4.20 are major engine versions. You do not update 4.19 to become 4.20. They are separate installations. To install 4.20, on the “Library” page, click the +] button to add a new engine slot, and choose the 4.20 Preview from the list of engine versions.
Each major engine release has new features, and fixes, that the previous did not. For a summary of what is available in 4.20, see here.
With every major engine release, we always perform Previews for a few weeks before the official release. We know that the Previews have some bugs, but this allows users to test the release, and find and report bugs that we might not have seen.
so that is something like beta version ?
Yeah. Same idea.
I am trying to solve this problems for days is it solved in 4.20 preview, also i have one mesh that i change UV to other and apply it brings some other UV… and they are overlapping all the time…
