Volumetric Billboards, and Grass Override
Hi,

These two would be great for my game. Can they already be done? If not, they can be low priority feature requests.

1. Add support for volumetric billboards, as here: http://www.antisphere.com/Research/Volum...boards.php

2. The option to improve (override or replace) the current grass & leaves system with volumetric billboards, or (in the case of grass only) just shell texturing/fur: http://www.youtube.com/watch?v=Hwxg59rdxeE

E.g. Realtime Grass using instanced Volumetric Billboards, for mid geometry, and full geometry for nearby, a Youtube video here: http://www.youtube.com/watch?v=8JQ--yA8i...re=related

3. Are these feature requests too time-consuming, or not feasible? I'm interested in your roadmap. I see you have some cool stuff like Voxel Terrain, and more platform support considered. I'd far prefer if you concentrated on cross-platform support than these kind of feature requests.

I find the current grass method far too expensive for my game (which is pretty low-spec), especially with shadows. There's too much distance between blades, for the performance<->quality balance, I had to remove all grass for now.

1. volumetric images are already supported (there is tutorial for that, please search for "volumetric" or "holographic" in file names)

2. you can play around with custom shaders, better built-in foliage is planned for the future

1. Thanks, I saw this before but never realised what it was doing, as I couldn't see what it was doing. It seems tough extending these over a surface, but will have a play somewhen.

2. Okay, I think i'll wait to see what better built-in foliage is like, and just have no grass up until then; lots of polishing and network security tests to do for now smile

Good luck with your current feature implementations.

The holographic tutorial is not very easy to understand. I think the problem might be that it uses a procedural sphere instead of doing all the steps of transforming a 3d object into the "voxels" and then displaying it with multiple instances.

If anyone could make an example, or improve on the existing tutorial, it would be great.
