So, here's the final set of shaders, which now incorporate a far nicer set of mud shaders and also a specular function for the grass blades.
There are 2 files to this upload; One .tgc and one .tgd. This is because the specular and patch gradients are features that need enabled, if they are required. The .tgd shows how this is done.
You can connect the layer in exactly the same way as the last one, that is, after your rock shaders but before your planet node.
The main shaders are now listed with 2 main group buttons, located in the node network area, for ease of navigation; 'a. Mud Shaders'
and 'b. Grass Shaders'
Enabling the specular function of the grass is very simple. Just select the new group button 'b. grass shaders'
and inside, you'll see a couple of new nodes. Your key to distributing highlights is the 'near and far distance'
fields in the new node 'Distance shader - Specular Gradient'
. Set your render camera to this node with a right-click.
Usually, you'll want the grass' highlights to appear close to the camera but not so far into the distance that they all blend together, making a horrid 'plastic' look. The .tgd shows that I have given the highlights a cut-off distance of 250m. This means that they will fade to nothing(because the 'far colour' is black) after 250m.
The default settings in the clipfile version has distance values of '0'. This means no highlights.
You can use the same idea for the 'Distance Shader - Patch Gradient'
node. You might want, for example, to adjust the 'near colour' of this node to take away any stray patches near your camera, if you'd like a more solid colour close to you. Your choice.
The default settings for patchiness are to have a complete patchiness covering of the entire shader. Blend in and out as you choose.
Here's the scene from the .tgd(I have some clouds in mine and my own personal rock shaders, that I'm also not including, the .tgd is just a plain atmosphere and the default 'base colours' node is the only rock surface but it's the same as this image in every other way);
Remember to click 'generate now' in the heightfield before you start with the .tgd file!
