You just have to unlock the wanted view-port from the scene’s Active Camera by de-activating this button: In short, by default, it seems you can’t assign different camera views to different view-ports.
BLENDER IMPORTING ANIMATION FROM 3DS MAX 8 UPDATE
If you split the view and in the new view select a different camera and set it as the Active Camera, the view in other view-ports set to camera view will update to display the new Active camera. * In Blender’s NLA editor, activate the actions you want exported to the FBX.ģds max & V-Ray to UE4 Datasmith workflowīy default, the view-ports Camera view in Blender displays the view from the camera that is set as the scene’s Active Camera. The “NLA Strips” option is useful for exporting a library of animations with the skeleton. * Un-related animations in the FBX can also corrupt the character rest pose in UE. Uncheck “All Actions” to avoid exporting actions that don’t actually belong to the skeleton. Set bones primary axis as X, and secondary axis as -Z. Uncheck the “Add Leaf Bones” option to avoid adding unneeded end bones.

In the UE4 import settings, choose the “Import Normals and Tangents” option in “Normal Import Method”: * For this option to be supported, the mesh geometry must have only triangle or quad polys.
BLENDER IMPORTING ANIMATION FROM 3DS MAX 8 FULL
This will make Blender export the full tangent space to the FBX and make UE4 read it from FBX instead of generate it automatically. You may want to check the “Tangent Space” export option, Make sure either “Edge” or “Face” is chosen in the “Smoothing” option to import the mesh’s smooth shading correctly ans avoid a smoothing groups warning on import:ĭepending on how much control you need over the mesh’s tangent space, Maybe the FBX exporter writes these settings to metadata that the UE4 importer doesn’t read.įrom my experience, what’s important is to orient the model correctly in Blender (see above), apply the transformations,Īnd in the UE4 import menu, check the “Force Front XAxis” option: However, in tests I did, The axis settings made no difference when importing to UE4, even when setting intentionally incorrect upside-down axes. There are axis settings in Blender’s FBX export module, that theoretically, should be set like this: UE4’s native model/world orientation is model’s forward facing the +X axis, left side facing -Y and up facing +Z. If you want to export Blender custom properties with to the FBX check the “Custom Properties” optionīlender’s native model/world orientation is model’s forward facing the -Y axis, left side facing +X and of-course up facing +Z. * It’s more efficient for me to select the specifics objects I want to export into a single FBX file prior to export, than to delete all the temp / reference / draft objects from the scene. I prefer the export settings to include only selected objects. I recommend saving an FBX export preset with these settings. * This is not critical at all because if baked as +Y it can easily be fixed in UE4.īlender custom properties import as UE4 asset metadata that can be read by editor scripts for automation purposes.įBX Blender export and UE4 import settings:

Set the normal map’s green channel to -Y. the Armature object is the root of the bone hierarchy. No need for a dedicated root bone in the hierarchy. * Also remember some weird related bug with animation scale incorrectly imported, but can’t confirm this now. Naming or leaving the Blender skeleton named “Armature” will cause the UE4 importer to fail due to “multiple roots”. Make sure the Armature object isn’t named “Armature”. Make sure to apply your model’s transformations before export. * This way the model is aligned to Blender’s views so the front view displays the model’s front etc.

Model your model in Blender facing the -Y world axis, +Z obviously being up (obviously for Blender). * Modeling in 1 meter units may seem to be imported correctly into UE4 but will cause unsolvable problems like a skeletal mesh physics asset having incorrect auto-generated shapes, a problem that in my experience can’t be fixed manually. Metric unit with 0.01 scale (centimeters)Īnd model your content correctly using centimeter units. * Some of the issues listed here may have already been solved It’s a list of tips I found to work well in my own experience. The following is a list of guidelines for preparation and export of 3D content from Blender to Unreal Engine 4 via the FBX file format.
