Yes, this is the 88x64 8k tileset mentionned earlier, it takes 428 GB on disk.
The VT is built with a "Amplify Texture/Legacy Shaders/Nature/Terrain/Diffuse" material and Vt properties are set to the following :
- HW level = Ultra
- Virtual Size = 1024k x 1024k
- Tile size = 512 x 512
- Mip Filter = Box
- UV Coord Set = 0
About layers, I used Albedo only, lossless compression (quality 80), and disabled Alpha.
I need to find a bigger hard drive in order to build a VT without hitting disk space limitation. I'll let you know when I can try again on a bigger disk.
Thank you for the additional information, we really appreciate it. That's odd, the resulting virtual texture should be considerably smaller than the original assets, we will have to run a few tests on our side. If possible, I recommend dividing your collection into 4 terrains, it might be the best choice in order to avoid the current problem. We will keep you posted on any new developments.
