![]() Make sure all your bones in the rig are parented to a main bone that has the entire model assigned to it to avoid parenting issues when Sketchfab converts the model. Learn how to reduce the number of keyframes with this tutorial by Dennis Haupt: How to Export an FBX file from Blender with reduced keyframes. Sometimes the Blender FBX exporter can crash on long animations. Unchecking NLA Strips and All actions works best for solid animation or rigs with only one action. This tutorial has been adapted from the community generated Animation Wiki.Įxporting with FBX 7.4 Binary usually gives the best results, just make sure that you select the Mesh & Armature categories and check Selected Objects to avoid complications. ![]() Also note that modifiers used on objects with shape keys will lost their effect: if you can't apply modifiers manually, they will not be applied on Sketchfab.An object animated by more than one armature.Another example: if you Mirror an animated object, you will not get the same result on Sketchfab. Animations based on modifiers that are not Armature modifiers: if you use a Hook or a Mesh deform modifier, its effect will be lost or buggy on Sketchfab.As workaround, you can generate vertex_groups from envelopes. Deformation by bone's envelope is not yet supported.There are still some of them that will have no effect on Sketchfab: All actions are baked using your current scene fps setting (so that the speed in the same within Blender and on Sketchfab)Īt the moment, we don’t support all Blender’s animation features.The duration corresponds to the current Blender scene duration If your scene has several animated objects : you get one single animation, where all objects are animated by their current active action.If your scene has only one animated object (action, nla_tracks): each available action leads to an animation with the same name.This is something we will improve in the future. Cardinal ), your animation will not look exactly the same once uploaded. So if you use other interpolation type (e.g. Note that the interpolation for absolute shape keys is not taken into account for now, it will always look as if it was set to Linear. Shape keys : we currently support relative and absolute shape keys.Constraints : objects moved by constraints in Blender will also be animated on Sketchfab.Armatures are animated by both solid and bone animation. ![]() Object are animated with solid animation.We are actively working to make this feature more robust and reliable, and we would love to get your feedback. Just make sure that the Import Animations checkbox is checked in the FBX Import Options dialog box.We support animations in the native Blender. The FBX can be imported into UE4 as usual. ![]() Enable Baked Animation, Key All Bones, NLA Strips, and Force Start/End Keying.In the Nonlinear Animation editor, make sure the checkbox of each action strip that you want to export is checked.We can export multiple animations by exporting NLA action strips. NOTE: Sampling Rate and Simplify are being set in order to improve the precision of the animation and avoid bone jitter or "swimming". Under the Animation tab, enable Baked Animation, set Sampling Rate to 0.1, and set Simplify to 0.0.Under the Armatures tab, disable Add Leaf Bones.Under the Geometries tab, set Smoothing to Edge or Face.Make sure only Mesh and Armature are selected.In the Export FBX options section, set the following options and then click Export FBX. Select the mesh and the armature (if there is one) that you want to export.Make sure the Start and End frame numbers are set correctly in the Timeline editor (or in the Properties editor, in the Scene tab under Dimensions).To export just the active animation (and include the mesh and armature): Make sure the Start Frame and End Frame of each animation are set correctly here, because these are the values that will be used when exported. You can use the Nonlinear Animation (NLA) editor to push the current action down into the NLA stack as a new strip. In order to export multiple animations in an FBX file, the animations will have to be stored as NLA action strips. If you plan to have more than one animation in your blend file, use the Action Editor context of the Dope Sheet editor to name each animation (called Actions in Blender) and to create new ones. ![]() You can find this setting in the Properties editor, in the Scene tab under Dimensions → Frame Rate. When making animations in Blender for UE4, make sure the frame rate is 30 fps because that is the animation frame rate that UE4 supports. The software versions used here are Unreal Engine 4.24.2 and Blender 2.80. Here are some basic notes and settings that I use for creating animations in Blender and exporting them for use in Unreal Engine. ![]()
