I wanted to implement a runtime 3D texture to splat moss/grass/snow etc on to a variety of geometry in our procedural levels. I ran into a few problems:
- There is no support for 3D textures or 2D texture arrays at all
- There is no good way of supplying a “global” texture to several materials.
We would very much appreciate 3D texture support and the ability to update (c++) them during runtime. I did not spot this on the roadmap,
but it seems like a pretty basic feature for a 3D engine in 2016.
If this is not something that is on the horizon, then including this texture array implementation in the next release would be epic :
