Libgdx 如何将blender 2.8制作的FBX转换为“g3db/g3dj”文件？

我尝试用libGDX转换一个简单的立方体，但立方体没有显示在我的游戏应用程序中

FBX文件是使用blender 2.8创建的

另一方面，如果我使用blender 2.76制作一个FBX文件，然后将其转换为g3dj文件，它将成功显示

工作与不工作之间的唯一区别是属性

TEXCOORD0

这里有2个g3dj文件，一个是用blender 2.76制作的，另一个是用blender 2.8制作的

这是一个有效的方法，使用blender 2.76创建FBX，然后转换为

g3dj

这是一个不起作用的，FBX使用blender 2.8创建，然后转换为

那么有没有办法在blender 2.8中省略这个属性呢？或者更好地让libgdx考虑这个属性

---

我在blender 2.8中使用漫反射BSDF材质

将不透明度设置为1而不是0。@Xoppa是的，我在发布后的几分钟内发现了，但为什么转换器将不透明度设置为

0

？我需要一个不需要编辑

g3dj

文件的解决方案，因为我使用它只是为了调试，我计划使用

g3db

尝试在blender中将不透明度设置为1，它可能被称为alpha，可能是材质透明度设置的一部分。@Xoppa我已经尝试过了，即使alpha已经设置为1，不透明度将设置为0，如果我在blender中将alpha设置为1.1，它将在

g3dj

中将不透明度设置为

-0.110000

如果我在blender

g3dj

中将alpha设置为

g3dj

文件不透明度将

0.799920

这是如果我使用纹理，如果我使用漫反射BSDF材质，它将不会在blender中显示alpha选项
