如何使用 Python 在 Blender 2.49 中设置世界背景纹理？

我正在尝试在 Blender 2.49 中设置背景世界纹理。

我制作了一个纹理：

import Blender 
from Blender import * 
import bpy 

world = World.GetCurrent() 
worldTex = Texture.New('worldTex') 
worldTex.setType('Image') 
worldIm = Image.Load('//blender_scene/tex/bg 001.jpg') 
worldIm.source = Image.Sources.SEQUENCE 
worldTex.setImage(worldIm)

当我尝试应用于世界时，会抛出错误，因为默认情况下 world.textures 包含一个 None 元组。所以这是行不通的：

world.textures[0].tex = worldTex

我已经制作了一种材质，这样我就可以获得一个 MTex 实例：

worldMat = Material.New('WorldMat')
worldMat.setTexture(worldTex)

如果我尝试设置第一个纹理：

world.textures[0] = worldMat.textures[0]

这将引发错误，因为我无法为已初始化的元组分配值。

如果我尝试替换它：

world.textures = worldMat.textures

我会收到另一个错误：

TypeError: expected tuple or list containing world MTex objects and NONE

“world MTex”对象让我思考了一下。还有另一种 MTex 对象吗？世界MTex？它在哪里定义的，如何创建实例？

或者正如标题所述......我如何为世界设置纹理？

谢谢

I'm trying to set a background World Texture in Blender 2.49.

I've made a texture:

import Blender 
from Blender import * 
import bpy 

world = World.GetCurrent() 
worldTex = Texture.New('worldTex') 
worldTex.setType('Image') 
worldIm = Image.Load('//blender_scene/tex/bg 001.jpg') 
worldIm.source = Image.Sources.SEQUENCE 
worldTex.setImage(worldIm)

When I try to apply to the world, that will throw and error, because, by default world.textures contains a tuple of None.
so this wouldn't work:

world.textures[0].tex = worldTex

I've made a material so I can get an MTex instance:

worldMat = Material.New('WorldMat')
worldMat.setTexture(worldTex)

If I try to set the first texture:

world.textures[0] = worldMat.textures[0]

That will throw an error, since I can't assign a value to an already initialized tuple.

If I try to replace it:

world.textures = worldMat.textures

I get yet another error:

TypeError: expected tuple or list containing world MTex objects and NONE

'world MTex' objects got me thinking a bit. Is there another kind of MTex object ? a world MTex ? Where is it defined, how can I create an instance ?

Or as the title states...how do I set a texture to a world ?

Thanks

Blender 2.5x 拥有更好的 Python API。我真的建议观看来自 PyCon 的视频演讲克里斯托弗·韦伯对此进行了介绍。

在 2.5x API 中设置纹理：

import bpy
# create new clouds texture
bpy.ops.texture.new()
t = bpy.data.textures[-1]
# set World texture
w = bpy.data.world['World']
slot = w.texture_slots.add()
slot.texture = t
slot.use_map_horizon = True

Blender 2.5x has a much better Python API. I really recommend watching this video from PyCon talk by Christopher Webber about it.

Setting texture in 2.5x API :

import bpy
# create new clouds texture
bpy.ops.texture.new()
t = bpy.data.textures[-1]
# set World texture
w = bpy.data.world['World']
slot = w.texture_slots.add()
slot.texture = t
slot.use_map_horizon = True
