Ursina-自定义模型拒绝纹理

Question

我在Python 3.8中使用Ursina，

我有一个为实体制作的自定义模型。我对该模型有一个纹理，从我的3D建模工具导出为.png图像。我尝试使用这样的纹理： entity（model ='monolith'，比例= 0.2，name ='monolith'，position =（50,0,100），collider ='网格'，color = color.dark_gray，texture ='/models/monolith'）

在游戏中，模型只是黑色。我尝试使用不同的模型，相同的结果尝试了这一点 - 自定义模型没有任何东西显示其纹理。

如何让Ursina纹理我的自定义模型？

对于这个具体示例，我正在使用.OBJ文件，但是我已经看到了.fbx，.glb和.stl 3D对象

如果有帮助，我用

您可以尝试entity.flip_faces（）在Ursina中添加此代码后，您的代码将看起来像这样：

fsmode = getinput("Fullscreen? [Y/N] > ")

if (fsmode == "Y"):fsmode = True
else:fsmode = False

以前的解决方案对我不起作用，这对我有用，我使用了底漆Panda3D库来处理正常方向的反转。

from ursina import *
from panda3d.core import GeomNode

app = Ursina()

# Laad je model
entity = Entity(model='your_model.stl')

# Toegang tot de onderliggende NodePath
nodepath = entity.model

# Normals omdraaien
for node in nodepath.find_all_matches('**/+GeomNode'):
    geom_node = node.node()
    for i in range(geom_node.get_num_geoms()):
        geom = geom_node.modify_geom(i)
        # Draai de geometrie om
        geom.reverse_in_place()

# Start de Ursina-app
app.run()
