| − | The TurfFX Effect Layer is an [[Effect Layer]] type which is used to render grass (and similar foliage). As with all effect layers, turf is painted onto the terrain and automatically generates appropriate geometry for the area surrounding the camera. As compared to the [[Clutter Effect Layer]], TurfFX offers less flexibility but substantial improvements to performance which in turn allows for greater density at greater draw distances and effective wind-synchronised animation.

| + | |
| − | | + | |
| − | A TurfFx asset is made up of individual polygon blades with many options to configure each blade in your Turf Effect Layer and within the asset itself. The individual asset creation process is explained in [[Effect_Layer_Assets]].

| − | | + | |
| − | Select a "Turf" asset you want to use in your turffx layer from the dropdown list. Once selected and named, you can customise how this particular layer will be configured wherever it is painted throughout the route.
| + | |

| − | Note that if you want short grass and long grass, you need to create two different TurfFX layers.

| − | ==== Turffx-Density Data Binding ====
| + | |
| − | | + | |
| − | The "turffx-density" options and associated "constant" value control the [[Effect Layer Data Binding]] (read this link for details) which controls the density of this turffx layer across the route. Density ranges from 0.0 (no turf present) to 1.0 (maximum density).

| − | [[file:turfdensity2.jpg]]
| + | |
| − | | + | |
| − | [[file:turfdensity3.jpg]]
| + | |
| − | | + | |
| − | NOTE: The turffx-density parameter (int1, int2, int4 ...etc) determines how accurate your density will be when painting with the height up/down and sensitivity radius in the topology tab. For example, int1 will give you 1 click while painting to get 100% density (off or on). Int4 will give you 1 click for 1/3rd density, 2 clicks for 2/3rds density, 3 clicks for 3/3rds density. Obviously the more accuracy you need the more data will need to be stored so use the appropriate data binding for the effect you require.

| − | ==== Turffx-Height-Scale Data Binding ====
| + | |
| − | | + | |
| − | The "turffx-height-scale" options and associated "constant" value control the [[Effect Layer Data Binding]] (read this link for details) which controls the height of this turffx layer across the route. Height ranges from 0.0 (no turf present) to 1.0 (maximum height).

| − | === Using Height Up and Down Tool===
| + | |
| − | | + | |
| − | Effect Layers are selected in the Advanced Topology Tab. When you change from Ground to any of the Effect Layers you have created, the Height Up, Height Down and Radius tools are used much like the tools in the Paint Tab.

| + | |
| − | | + | |
| − | === Using Area Fill Tool===
| + | |
| − | You can also select an area and fill the area with your selected Effect Layer Binding. Set the Effect Fill Density slider when using the Fill tool to adjust the density of your effect layer.
| + | |
| − | | + | |
| − | === Painting Tips ===
| + | |
| − | * Effect Layers are data intensive, and so you need to work out where you require precision (e.g. in highly visible areas) and where you can use much less precision (e.g. away from the track areas)
| + | |
| − | * Using 2.5m precision everywhere will consume your scene budget very quickly.
| + | |
| − | * Using the turffx-height-scale tool will raise or lower existing effect layers only. (i.e. you need to paint some density prior to adjusting the height)
| + | |
| − | * Experiment with different values such as using 0.001 for dispersal to get that "clumpy" look (then try 0.05, 0.5 etc for different looks)

| − | =Surveyor Bulk Editing Tools=
| + | |
| − | | + | |
| − | In future updates we plan on expanding the TurfFX tools to enable global updates such as adding a TurfFX layer to an existing ground texture. These tools, when introduced, will greatly speed up the conversion process from older routes.
| + | |
| − | | + | |
| − | =Hardware Limitations=
| + | |
| − | TurfFX is developed by NVIDIA and is designed to takes advantage of high-end GPU's with substantial amounts of VRAM.
| + | |
| − | | + | |
| − | 1. TurfFX is currently supported only for Windows.
| + | |
| − | | + | |
| − | 2. Whereas Trainz will typically run (albeit slowly, or at reduced settings) on below-spec computers, TurfFX will need to be disabled entirely if the GPU is insufficient. We expect the minimum of a GeForce GTX 750 to get reasonable performance.
| + | |
| − | | + | |
| − | 3. With TurfFX disabled, the Effect Layers are ignored entirely, and there is no performance penalty for those objects that are disabled.
