[英]How do I set a world background texture in Blender 2.49 using Python?
I'm trying to set a background World Texture in Blender 2.49. 我正在尝试在Blender 2.49中设置背景世界纹理。
I've made a texture: 我做了一个纹理:
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)
When I try to apply to the world, that will throw and error, because, by default world.textures contains a tuple of None. 当我尝试应用到世界时,会抛出错误,因为默认情况下world.textures包含一个None的元组。 so this wouldn't work:
所以这行不通:
world.textures[0].tex = worldTex
I've made a material so I can get an MTex instance: 我已经制作了材料,因此可以获得MTex实例:
worldMat = Material.New('WorldMat')
worldMat.setTexture(worldTex)
If I try to set the first texture: 如果我尝试设置第一个纹理:
world.textures[0] = worldMat.textures[0]
That will throw an error, since I can't assign a value to an already initialized tuple. 这将引发错误,因为我无法将值分配给已初始化的元组。
If I try to replace it: 如果我尝试更换它:
world.textures = worldMat.textures
I get yet another error: 我又遇到另一个错误:
TypeError: expected tuple or list containing world MTex objects and NONE
'world MTex ' objects got me thinking a bit. “世界MTex ”物体让我有些思考。 Is there another kind of MTex object ?
还有另一种MTex对象吗? a world MTex ?
世界MTex? Where is it defined, how can I create an instance ?
它在哪里定义,如何创建实例?
Or as the title states...how do I set a texture to a world ? 或者如标题所述...如何为世界设置纹理?
Thanks 谢谢
Blender 2.5x has a much better Python API. Blender 2.5x具有更好的Python API。 I really recommend watching this video from PyCon talk by Christopher Webber about it.
我真的建议您观看克里斯托弗·韦伯(Christopher Webber)的PyCon演讲中的这段视频 。
Setting texture in 2.5x API : 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
