Known issues¶

Format	Output software	Issue	Cause
Wavefront	3ds Max Wavefront OBJ Expoter v0.97b	Conversion of materials may be fail.	Output software may output invalid file format. See also spec
Wavefront	3ds Max Wavefront OBJ Expoter v0.97b	Textures may not be recognized.	Output software may output invalid file format. See also spec
DirectX	ToyStudio 1.6.2.6	The model file may not be recognized.	-

Common specifications in all model formats¶

Coordinate system (OpenGL compliant)¶

3DCGARTS assumes 'Right-handed coordinate system'.
But, 3DCGARTS converts coordinate system internally, so you don't have any configuration on your software.

Shader¶

Method	Supporting status
Constant	o
Lambert	o
Phong	o

Texture mapping (Expansion method)¶

Method	Supporting status
UV	o

But, 3DCGARTS does not support Multiple UV Map (Multiple textures are mapped to a material).
When you use Multiple UV Map, the texture will be uncertain.

Texuter mapping (Representation method)¶

Method	Supporting status
Diffuse Mapping	o
Normal Mapping	o
Specular Mapping	o

Drawing texture includes transparency¶

Z value of textures will be ignored.
To set transparency, see here (Japanese only).

3ds Max¶

The restrictions of 3ds Max file.

• Max vertex numbers of a object
  • around 60,000
• Max polygon numbers of a object
  • about 20,000
• Texture file name
  • ASCII character
    • Less than 8 characters

Autodesk FBX¶

• 3DCGARTS supports both ASCII and Binary format of FBX 2011 or later.
• When you want to output as FBX 2011 or later, download plugin from the following site:
  • http://usa.autodesk.com/adsk/servlet/pc/item?id=10775855&siteID=123112
  • After installed the plugin, you can choose output file format as follows:
    • 

Blender¶

• Shadeless Enable
  • Constant
• Shadeless Disable
  • Phong

Metasequoia¶

Visible¶

• The viewer show visible objects only.

Vertex¶

Method	Supporting status	Memo
Bertex	x	Binary Vertexes（Metasequoia 1.0 〜 2.1）
Vertex	o

Vertex color¶

• Unsupported

Field¶

Method	Supporting status	Memo
Side	x
Triangle	o
Rectangle	o	A rectangle will be divided into triangles forcibly.

Smoothing¶

Method	Supporting status
Smoothing	o
Smoothing angle	o

Object¶
