Nice job! looks nice.
Easiest workaround would be to combine all the sub-meshes before unwrapping, so that itās one model, instead of several.
Great work so far guys! Been keeping an eye on this for a while and itās really progressing along.
Actually I think I can merge them in blender after UV mapping. But I am not sure if this has any unwanted side-effects.

Thanks
:
Please notice the vertex-count. It has doubled because I exported it form blender with āFlat shadingā. Otherwise the model wont look nice. It will average the normals at each shared vertex and this results in a mesh that is too smooth.
Another problem. There is gap on the floor at the very back (near the pillar, behind the hut). Also there are plenty of hidden polygons and there, and some faces (especially the hut) has double faced polygons. I have not UV mapped those faces, so if the camera cuts into the mesh, the result is not very pretty 
@everyone else:
The model contains a hidden pillar inside the big tower geometry. I did not UV map it as it is never visible. If anyone thinks I should UV map it, please let me know.
7 materials is still 7 draw calls, doesnāt matter if they are sub-elements of the same mesh
When I merged, blender only shows a single material. It does not show multiple mappings in UV editor
so blender re-arranges all UVs into a single UV sheet?
in any case check in unreal, donāt trust only what you see in blender
Yes, Thats what I saw. I painted into one material using blenderās texture paint mode and it was applied properly to the entire model. Also I did not UV map each element separately and there is only 1 UV map. But it seems to work work fine in blender. I only noticed the 7 elements after importing into UE4.
Is master branch still crashing? I merged 's pull request but master branch is still crashing for me. 
Now iām confused. Master branch is crashing for me, but my branch isnāt, but shouldnāt they be the same since we merged them? Does my branch also crash for you?
When you do a merge, both branches are combined NOT overwritten. Also they consider the commit time of the branches to decide which change to keep and which to discard. I dont know how this is going to work in binary files. After all git is designed to work with text files
I expected that they would combine, but since almost all files (especially the ones related to the crashing BPs) got updated i figured it should work the same as my branch. I didnāt know about the keeping/discarding changes, thanks for explaining.
Today i loaded the project (master) and it worked fine
Github showed a lot of new files to commit but i discarded all of them and now this crashes
Nope. It works fine.
so you assign 7 materials to it, correct? this means 7 draw calls, even if itās the same material applied 7 times
Actually I am redoing it again. Lets see if I get it right this time 
Thanks for the pointers
Hello all,
Looks like the thread has been idle for a while.
I have good news! I have managed to merge the barrack model within blender and redo the UV mapping. Now Unreal shows only 1 element. So no more issues with 7 elements.
Also I have done the 4 stages of construction for the Barrack model and made sure they all share the same UV layout.
When you have resolved the issues with Git, I will push it there.
Great! I canāt wait to see the results. Iāve just pushed some changes to Master which should fix the problems, but you might want to test it before pushing something new.
The thread may have been going idle but not me, currently iām working on a way of managing upgrades for the player and the buildings & units. Iām also still figuring out the Godcamera since it needs to be fixed.
How is the construction system progressing?
I imported the 5 stages of Barrack into Unreal and the results are great!
You can see the results in the attachments.
The only real issue is on stage 3. As you can see the 4 pillars of the barrack building is made of single sided faces and so they will be invisible from one side.
I also tested them with the construction manager and the transition is perfect. I am having some trouble with video capture at the moment, but I will post a video soon
Awesome !
Since now 4.5 Preview is available has anyone tried this with 4.5? Is that bug fixed?
As promised, is a video of construction manager in action. AND you can see the different stages of Barrack building created by ://www.youtube.com/?v=ReAPBtAaqSk
Indeed very awesome , canāt wait to see it fully implemented.
And i have tried with 4.5 Preview and the bug was fixed.
