This apply land and grass material in blender 3D post is actually a continuity from island project part 1. If you just stumble upon to this article, go check how to create an island in blender 3D if you want to. But honestly, this posting can be a standalone tutorial.
Open your island object. This is mine from the last tutorial:
1. First we will create a land material. Select your object and create a new material with diffuse color light brown with specular intensity = 0, so it won’t be too shine, and then rename the material to land. Next create a new texture and upload your land/sand material image.
2. Back to material editor, click + sign & new button, and then rename it grass. Choose a light green as diffuse color and again set specular color 0.
Create Grass From Hair Particle in Blender 3D:
If you’re a beginner and confuse in what way we can create a grass material in blender 3d, the answer is with hair particle feature. Select the surface object and on particle editor click new button. Follow the parameter setting on yellow box below:
If you try to render it, the grass is look like not fertile enough. This is the time where we play with other parameter like children option, so it’s more dense.
Now, you will have more heavy grass but unfortunately the render time is a little bit longer, huh?.
As you can see the height of grass are the same. That’s not really happen in real environment, right?. If you want to see more varieties, play around with Roughness Uniform value like 0.1. The bigger number you enter, the more varieties and fall apart your grass are. For heights change all the value on Render: Timing.
Go head, experiment with all parameter on particles editor. Just to remind you though the more complex setting you make, the more heavy your computer to render. You can make grass display more simple by active Strand Render and Child Simplification, but you probably won’t like the render result though.
I honestly happy with my grass setting so far. My last little touch is adjust the thickness by go to material editor —> strand —> change size root: 1.5000; tip: 0.2500. Here’s my final result for grass setting:
Weight Paint Use in Blender 3D:
Weight paint use in this exercise project is simply to display a different area on surface which is an area that has grass grow and land area. Adding this cool effect will make your project more realistic. On interaction mode, switch to weight paint and change viewport to top view. I found it helpful so you don’t have to 3d rotate the whole time. Don’t forget to set weight = 1, which mean the area you will brush ( red color ) is where the solid grass are.
And vice versa to remove grass ( blue brush ), change the weight value to 0.
Tip: On particle editor —> Vertex Group : Density = Group to make your brush result visible.
Switch to Object Mode, and now we can see more clear the difference area between grass and no grass.
Okay, that’s it for now friends. I hope you can follow all instruction above. Next we will add water on our little island, make sure to bookmark and subscribe to this blog. If you think this apply land and grass material in Blender 3D tutorial is helpful, don’t forget to give some love below!.
