HELP : Vegetation Real Time

Realextalk · Jul 2017

Hi polycounters,

I'm struggling with realtime vegetation, so i'd like to know if someone can advise me on what soft to use and if there are some tutorials.

Thanks a lot

Show us what have you done so far.

@Obscura

haha I've done nothing so far, i want to train myself and i don't know where to start.

How do you struggle if you haven't even try anything? Does it hurt also hurt?

Realextalk · Jul 2017

@Obscura I just don't know which soft or which method i have to use to get the proper workflow

What software do you currently use? Asking what DCC to learn for real-time vegatation creation specifically is like asking what brand of guitar to get to learn Stairway to Heaven.......

Or are you asking about a specialist software like Speedtree? Try to be a bit more helpful in posting threads like this. Otherwise we won't take you seriously.

I'm currently using Blender and Unity

@Realextalk - A great place to start might be looking at the Speedtree for Unity toolset, they have good beginner tutorials on the Speedtree Youtube page https://www.youtube.com/user/SpeedTreeMiddleware

I would not recomend speedtree if he doesnt know how are these even made. Let him make some vegetation to understand it and then he can subscribe on speedtree.

In vegetation you generally model the branches, and the leaves are 1plane each with maybe a few subdivisions (basically called cards) that uses a leaf picture and an opacity mask to cut the area outside the leaf. Grass can be made out of tapered splines and generally these two methods are mostly used for making vegetation.

Most games don't use tapered splines for grass, that's too expensive, too many vertices (memory cost) and the triangles are too long and thin (rendering cost).

See the wiki for game grass methods. Most often, grass is made using planes.

Speedtree I believe is the most painless method, and can be adapted to use photoscanned assets, comes with animation etc.

At least with Speedtree you are able to open an example tree, and see the raw meshes and textures that went into its creation, doing some backwards engineering. To me thats way easier to learn what components are necessary, if not easier than starting from an empty scene and stumbling through older methods. Speedtree still requires that you make all the raw elements in order to create the foliage.
