8k Texture import for Gear VR

Hello,

I'm having trouble importing an 8k by 8k texture to Unity. The import takes a while to process and when the import is finished the texture is purple like always when there is a texture import error. Importing the same texture with the same settings, but limited to 4k by 4k works fine.

The texture is a stereo 360 latlong image and is supposed to be used with the new panoramic shader on the Gear VR. So VR support is enabled and Texture Compression in Build Settings is set to ASTC as recommended in the Oculus Documentation. I also disabled MipMap generation since the texure is used on the skybox only.

I already tried a clean project as well with only the texture in it and also on Mac and PC, but I had the same problems.

Any help is greatly appreciated!

Thanks,
Chris

 

For everyone stumbling upon this post, I found at least a way to make this work. When Generate Mip Maps is enabled the texture is converted properly, but be aware: it takes ages with 8k textures and ASTC compression.
