Why Cant I Upload a Mesh Roblox

This article summarizes how to upload meshes to Roblox from models created in Autodesk Maya, Blender, etc.

Uploading Meshes

The easiest fashion to upload meshes is through the Import push button of the Asset Manager window (View tab → Asset Director).

Upon completion, this will create one or more mesh assets in the Meshes folder:

By default, a file consisting of multiple meshes will import into Studio every bit dissever meshes. If this is not your desired outcome, check Import file as unmarried mesh when importing the file.

• If any kid mesh contains more than than 5000 polygons, the parent mesh will be rejected.
• If a parent mesh contains more than than fifty child meshes, all children meshes will be rejected.

Inserting Meshes

To insert a mesh into your game, right-click it and select Insert. Alternatively, if the mesh contains location data, you may preserve it upon insertion by selecting Insert With Location.

This volition insert a MeshPart case with your mesh applied:

Applying Textures

A mesh file can ascertain a path to a texture for a mesh. If this is set and the path is valid, the texture will automatically exist practical when the mesh is inserted.

If the texture is non inserted automatically, one can exist practical to a MeshPart past setting its MeshPart/TextureID|TextureID, either in Studio or at runtime through a script.

To apply a mesh texture in Studio:

1. Select the MeshPart object inside the game editor view or Explorer hierarchy.
2. In the Properties window, click on its TextureID field.

In the context popup window, the texture tin be applied in diverse ways:

• Select any prototype (texture) that you previously uploaded.
• Upload a new texture by clicking the Add Image… button nearly the lesser of the popup.
• If yous know the Roblox asset ID for the texture, for instance rbxassetid://0123456789, you can paste it into the URL field at the elevation of the popup.

Collision Geometry

Similar UnionOperation|UnionOperations, MeshPart|MeshParts take a CollisionFidelity property. This setting determines how closely the visual representation of the object matches the physical bounds of the object. See MeshPart/CollisionFidelity|CollisionFidelity for more information.

Level of Detail

By default, meshes volition always be shown in precise fidelity, no matter how far they are from the game photographic camera. This improves their appearance when viewed from whatever distance, simply if a place has a large number of detailed meshes, it may reduce overall game articles/Improving Functioning|functioning.

To dynamically command a mesh part'southward level of detail, alter its enum/RenderFidelity|RenderFidelity property to Automatic. This will cause the mesh to be rendered at a different level of detail depending on its distance from the camera:

Altitude From Camera	Return Allegiance
Less than 250 studs	Highest
250-500 studs	Medium
500 or more studs	Lowest

Troubleshooting

With mesh importation, certain issues tin occur. Well-nigh of these are caused by a misunderstanding of what Roblox allows on importation. The following are some common issues and an overview on how to prepare them.

Scenario	Solution
Import Issues With Complex Multi-Mesh FBX Files	Complex .fbx multi-mesh files may not import correctly, causing unexpected mesh positions or rotations. One workaround is to use the Wavefront (.obj) format instead. If you're exporting from Blender, make certain each mesh is exported as a group: Uncheck the Objects equally OBJ Objects checkbox. Check the Objects every bit OBJ Groups checkbox.
Model Contains Rigging or Blitheness Data	Studio does not currently support blitheness or rigging data importation. If your mesh is reliant on an initial transformation based on blitheness/rigging data, it will not be preserved and your mesh may expect wrong. To fix this, remove the blitheness/rigging nodes and upload the mesh again.
Extremely Large FBX Files Exported From Blender	Blender may apply a scaling factor when exporting a mesh equally an .fbx file, depending on its settings. This may result in oversized meshes when importing into Studio. At that place are at least two ways to prevent Blender from applying the scaling factor: Export every bit Wavefront (.obj) instead of .fbx. Blender will not apply whatever scaling factor, so one unit of measurement in Blender will equal one stud in Roblox. Use centimeters as the default unit instead of meters (this tin can exist changed in the Scene properties of Blender).
Out of Bound UVs	UVs map the location of the texture to a position on the mesh. UVs exterior the bounds of the texture are drawn as if they're still within the texture, resulting in a tiled texture. This can be fixed by remapping the mesh with UVs inside the bounds of nada and one.
