The OpenGL problem is duplicate of bug
4829458 - Some Texture stage fail to disable in accelerated mode for multiTexture apps
which is filed on behalf of Justin's demo earlier this month. This is not a switch problem.
For DirectX version, bug
4838311 - D3D: TextureAttributes in texture stage need to reset for multitexture
is filed for this. Here is the evaulation of this bug :
When using multitexture in DirectX version of Java3D, it is expect that the texture stage set in stage 1 can be disable by setting null texture
device->SetTexture(1, NULL);
so next time texture attributes in stage 1 will not affect stage 0.
However, it turns out that this is not the case. In this example, 2 Spheres are drawn, the first one (bump) use texture stage 0 and 1. The second one (color) use texture stage 0 only. When rendering the second sphere Java3D set texture in stage 1 to null. But without reset texture attributes in stage 1 back to default value the image is shown as white.
It can be reproduce using DX reference device. I'm not sure if this is DirectX bug or not but we'll workaround this.
Both bugs are fixed in the upcoming v1.3.1 release.
Thanks.
