MQOZ (Metasequoia)

This is an original file format of Metasequoia and supports all functions.

Triangle	Quadrangle	Polygon	Normal	Material (Color)	Mapping	UV value	Vertex color	Blob	Bone	Morph
ok	ok	ok	ok	ok	ok	ok	ok	ok	ok	ok

SUF (DoGA CGA System)

This is the format used in DOGA-L series or PolyEdit.

It is mostly available with all functions.

Triangle	Quadrangle	Polygon	Normal	Material (Color)	Mapping	UV value	Vertex color	Blob	Bone	Morph
ok	ok	ok	NG	ok(*1)	ok(*1)	ok	-	-	-	-

(*1) Attribute (Material) handles the file which has the same name of extension, ATR.

DXF (AutoCAD)

This can load only files mentioned in "3DFACE". If DXF file cannot be loaded, please confirm what information the software of the exporting side is exporting.

I cannot highly recommend the exchange in this format because it can hold only data of shape, for this is the format not only for CG but also for CAD originally.

As the format does not have the direction of faces, it is not guaranteed and sometimes needs to be mended.

Triangle	Quadrangle	Polygon	Normal	Material (Color)	Mapping	UV value	Vertex color	Blob	Bone	Morph
ok	ok	-	-	NG	-	-	-	-	-	-

LWO (LightWave3D)

It is available with LWOB format up to LightWave3D 5.6 and LWO2 format after LightWave3D 6.0. The file saved the format with a layer of 5.x cannot be read.

	Triangle	Quadrangle	Polygon	Normal	Material (Color)	Mapping	UV value	Vertex color	Blob	Bone	Morph
LWOB	ok	ok	ok	not good (*1)	ok	ok(?)	-	-	-(?)	-	-
LWO2	ok	ok	ok	NG	ok	ok	ok(*2)	ok	NG	-	-
LWO3	ok	ok	ok	NG	not good(*3)	ok	ok(*2)	ok	NG	-	-

(*1)It is only supported to import smoothing angle.

(*2)When some UVs by multi-texture are assigned to one face, only one of them can be read.

(*3)If node-based shader is used, it may not be imported correctly.

3DS (3D Studio)

This format was used by 3D studio for MS-DOS (3ds Max's antecedents).

The format is very old, and it contains triangle faces only. And a maximum number of vertices and faces are 65536. There are many restrictions, and it is not recommended to use currently.

Triangle	Quadrangle	Polygon	Normal	Material (Color)	Mapping	UV value	Vertex color	Blob	Bone	Morph
ok	-	-	NG	ok	ok	ok	NG(?)	-(?)	-	-

ROK (Rokkaku daioh)

As the direction of faces is not defined in the format itself, it is not guaranteed and needs to be mended in cases.

Triangle	Quadrangle	Polygon	Normal	Material (Color)	Mapping	UV value	Vertex color	Blob	Bone	Morph
ok	ok	-	-	ok	-	-	-	-	-	-

COB (trueSpace)

The file saved in ASCII (text) format cannot be read.

As the hole opened by like Boolean cannot be handled, it will be closed. Please triangulate polygons on trueSpace beforehand in this case.

Triangle	Quadrangle	Polygon	Normal	Material (Color)	Mapping	UV value	Vertex color	Blob	Bone	Morph
ok	ok	ok	NG	ok	ok	ok	NG	ok(*1)	NG	NG

(*1)Blobs with simple shape and polygonization are loaded as polygon objects.

OBJ (Wavefront)

Invert V of mapping

As how to arrange values of V(vertical) direction in UV mapping becomes upside down, it becomes necessary to choose the applicable one.

Join closed vertices

It joins the closed vertices in the same object. It is mainly used to join vertices which seem to be close by appearance but really are separated.

Use groups

If you check it, groups of objects can be imported.

Import vertex colors (*2)

If you check it, you can import the vertex color setting.

Import vertex normals

If you check it, you can import the vertex normals from the file.
When the vertex normals are imported, the vertex normals of objects are fixed. If you want to edit shape of objects, you may not need to check this item.

utf-8 encoding

If you check it, the character code in the file is read as utf-8.

If there exists data written in some lines, it sometimes fails to load them.

Triangle	Quadrangle	Polygon	Normal	Material (Color)	Mapping	UV value	Vertex color	Blob	Bone	Morph
ok	ok	ok	ok	ok(*1)	not good(*1)	ok	ok(*2)	-	-	-

(*1)A material library(MTL file) is loaded automatically if it exists in the same folder of OBJ file. It can only keep the name of material assigned to faces if there isn't the MTL file.

(*2)Since the vertex color of OBJ is a non-standard specifications, only part of the software is supported.

DAE (COLLADA 1.4/1.5) (only EX edition)

Coordinate

It specifies which a right-hand coordinate or a left-handle coordinate is used.

Invert faces

It reverses a direction of a face.

Scaling factor

It specifies a scaling factor.

Invert texture V coordinate

As how to arrange values of V(vertical) direction in UV mapping becomes upside down, it becomes necessary to choose the applicable one.

It supports COLLADA 1.4 and 1.5. Other versions of COLLADA cannot be loaded.

FBX (Autodesk FBX) (only EX edition)

Write embedded texture files

If a texture image is embedded in the file, the texture image file is export to the same folder as the loaded file.

Load Normal

You can import the vertex normals from the file.
When the vertex normals are imported, the vertex normals of objects are fixed. If you want to edit shape of objects, you may not need to load normals.

Remove unused nodes

If there are unused nodes in the file, exclude them.

When the division level is set, the type of the patch becomes OpenSubdiv and weight of vertices or edges are loaded.

PLY (Stanford Polygon Library) (only EX edition)

Faces ('face') or points ('range_grid' or vertices coordinate) data are supported.

STL (Stereolithography) (Standard/EX edition only)

Both ASCII and binary files are supported.

SVG (Scalable Vector Graphics) (only EX edition)

You can import a vector image that was created in a vector graphics software.

Creation method

• Path only: It is to import the path only as a line.
• Outline: It is to import only the outline of the line and surface. The color is ignored.
• Fill: It is to import the line and surface as a plane. Materials are divided into each color.
• Solid: It is to import the line and surface with a thickness on the surface. Materials are divided into each color.

Clip overlapped area (Takes time)

(*Only when you select [Fill] or [Solid] in [Creation method])
When checked, it is imported by calculating the order of the overlap of the closed path.

None	Checked

Thickness

When you select [Solid] in [Creation method], you can specify the thickness of the object.

Change thickness by brightness

When attaching a thickness, if the check, the thickness is increased or decreased depending on the color of the surface. Color high brightness is thick. Dark color is thinner.

Curve precision / sampling #

When you import a path with a curve, the reproducibility of the curve is specified in the accuracy(25-1000) or the number of divisions.

When output the SVG files from Adobe Illustrator, specify "SVG Basic 1.1" in SVG profile. And convert fonts to outlines.

(*1)Part of the specification of SVG is not supported. For example, gradients and textures and clipping are ignored.

PMD (MikuMikuDance) (Standard/EX edition only)

Load Facial

Select whether or not to import the morph information.
If you select [Enable], morph part is divided into different objects as "MorphBase".

Load Normal

You can import the vertex normals from the file.
When the vertex normals are imported, the vertex normals of objects are fixed. If you want to edit shape of objects, you may not need to load normals.

glTF(glTF 2.0) (Standard/EX edition only)

It is supported to import JSON format(.gltf) and binary file(.glb).

Use glTF shader

If this item is checked, materials of this glTF file object are displayed by glTF shader.

Write embedded texture files

If imported glTF file has texture image, checking this item, texture image files are written to the same folder that imported glTF file is in.

Remove unused nodes

If there are unused nodes in the file, exclude them.
