How to Upload Custom Skeleton to Blender

For Waystation Echo, I am using a custom armature based off of the UE4 mannequin. Since I want to do making FPS arm animations, I decided to abandon any delivered stuff designed for the mannequin and brand my ain armature. Since this is a unique skeleton, I wanted to go over how I exported it from Blender and then successfully imported it into Unreal.

In Blender

I'm assuming you already have a mesh that you added bones to.

Consign your mesh and your bones together every bit selected objects. Don't select anything else:

In the Export FBX panel in your sidebar, set your Forwards vector to -Y Forward, which automobile changes your Up vector to Z upwards:

Note that I selected onlyArmature in the to a higher place screenshot. This is because I am intending to consign the **animation **I made for my artillery–an idle break animation.

If you are exporting your fbx for the first time, then this is likely your base of operations pose. In that case, you'll want to ensure you lot select the Mesh tab is also selected:

In the Geometries tab, I always prepare Smoothing to edge:

In the Armatures tab, I ensure thatAdd Foliage Bones is unchecked. I don't want actress bones in my bones:

In the Animation tab, what you lot select will be dependent on what state you lot are exporting.

If this is a base pose, not but do you desire to ensure that you selected Mesh in improver to Armature from the Main tab, you also want todeselect Baked Blitheness, which will uncheck the remainder of this tab's elements:

If this is an animation for your base pose, ensure that your Baked Blitheness is selected–otherwise you'll just be exporting a static pose:

At this betoken I'll assume you've exported your FBX at to the lowest degree twice: one time for the base pose with the Mesh and no animation, and once more than with no mesh merely baked animation.

Let's at present await at bringing it in to Unreal.

In Unreal Engine

I saved my base pose every bit WeFPS_Arms, and my fbx containing the blitheness WeFPS_ArmsAnim_IdleBreak.

The first affair to practice is bring in your base of operations pose. Go to your content browser and click Import, then select your FBX containing the base of operations pose that has no broiled blitheness. In Unreal's FBX Import Options, ensure thatskeleton is None (which will crusade Unreal Engine to generate a new skeleton based on the one in our FBX) and that Import Animations is unchecked. Overall, your import should look something like this:

One time Unreal Engine is washed importing the FBX, y'all should see 3 new things in your content browser: The Skeletal Mesh, The Physics Asset, and the Skeleton:

If yous have animations, Import the FBX in the aforementioned mode. Notice that Unreal'south FBX Import Options looks unlike: kickoff, the Skeleton is auto assigned to the 1 it just generated before, and 2d, in that location's no option to not import the animation–since that wouldn't brand any sense:

Once you're done importing the animations, your content browser volition show you two new things: your blitheness + "root root", and your animation + "root rootAction." The erstwhile is your blitheness asset's commencement frame; the ladder is your blitheness nugget's animation:

Nosotros can test this by modifying our current blitheness patternor just creating a new 1. For the purposes of this article, I just created a new one, then modified the design I employ to govern my player to use the new anim blueprint–and to use the Skeletal Mesh that we created when importing our FBX:

For this example, I went to that custom anim blueprint and but had it loop the idle loop blitheness:

The last thing yous need to remember to practise is SAVE EVERYTHING, then Compile your anim design. Yous demand to save the skeletal mesh, the skeleton, the animations, and the anim design. One time they're all saved, hit Compile. Once your player'due south BP is in the game, give it a become. Here's the commencement circular of my tests:

The animation loops expect neat. I have some placement tweaking to do (see that behemothic shoulder upward there?), but overall, I would say it'due south getting closer and closer to the final product.

I hope this article was helpful to you lot! Adept luck and stay productive. ♥
