Interactive Door Blueprint - Custom Meshes

You may want to add your own set of doors or door handles to the door blueprint. This page explains what you can do.

I downloaded this free set of door handles from 3D Sky.

Door Handles Set - 3D Sky

Best to place their origin at 0,0,0. You can also use the Transform in the setting to align them, but you would have to do this every time you use the new handle.

There are 2 meshes now that can be imported into unreal

• SM_3DSky_Handle01
• SM_3DSky_Plate01

I did not import Materials from the 3DSky package. There are already metal materials in the project.

A few tips:

• The handle is quite thin. Arch Viz mesh details tend to be a bit on the thinner side and can look flimsy in Unreal.
• Small detail gets lost. You have to exaggerate small details to be visible or use normal maps.
• Everything needs a chamfer. But it will be invisible if too small.
• Rely more on geometry instead of smoothing groups. Add lines on edges where it matters. Dividing a flat plane multiple times in the middle doesn't improve anything.
• Use Nanite whenever you can.

Optional, the glass can be separated into a Glass Mesh to make the door mesh work with Nanite prior to version 5.4.

The door mesh ideally should be located with its right front bottom edge on the 0,0,0 origin and rotated in negative Y position.

There is an auto fit option for doors in the blueprints.

Auto Fit Doors

• S (small) 720 x 2040 x 40 mm
• M (medium) 820 x 2040 x 40 mm
• L (large) 920 x 2040 x 40 mm

• S (small) 720 x 2340 x 40 mm
• M (medium) 820 x 2340 x 40 mm
• L (large) 920 x 2340 x 40 mm

The door blade width is listed in brackets in the drop-down list. The identifier (MH = medium high) is part of the mesh name, for example SM_MH_DoorA. I recommend naming custom doors the same way.

Sizes can be Nominal and the actual size may be slightly different than the nominal size. You or the user don't need to care about those details. It works under hood.

Step 1 - Enum_DoorType

The enumerator has the list of door type names in it. You can either use Door X which is an empty element, or you can add your own enumerator by clicking on + Add Enumerator

Be careful not to delete, rename, or move any of the existing enumerators. Best to just add a new enumerator at the end.

Every door type has a function in the BPL_UniDoors library. The Get Door X is an empty function you can use. Or duplicate the function it for a new door style. Door types 04 and 05 have a glass mesh which can be ignored at this time.

• Duplicate the Get Door X function and rename it.
• Import your set of 6 doors into a folder for the type
• Add the doors to the slot for the size S, M, L, SH, MH, LH
• Make sure the function is set to pure
