How would I achieve this sort of way of fading sand onto the floor:
But at a larger scale as my scene is not close up like the image.
Any help would be greatly appreciated,
Thanks
Welcome to Blender Artists!
I only know 3 ways to do this. The first would be to create a custom texture, and the second would be using the new particle nodes. I am not experienced enough in either of these areas to give any solid advice though. The last way you could do this is with a particle system and weight painting. You can find more about this online, but here are the basics:
- Create the surface that the sand will be on (AKA a plane or something).
- Subdivide this as many times as you want (the more the better, but you don’t want to create too many vertices).
- Go into weight painting mode and paint out the areas that you want the sand to be (red means it will have the most sand there, blue means there is none)
- Assign that as a new vertex group.
- Create a hair particle system, with an object as your sand.
- Under the Feild Weights category, set the vertex group you made earlier as the density.
- Play around with the particle settings and sand material until you get the result you want.
Tip: you can use a color ramp in the material nodes area on the sand material to create a variety of colors.
I hope this helps you. If you need any clarifications, just let me know! I hope you have a great day!
if your image is not close-up you could even use the image you show as a b&w mask to show and hide a noisy texture

Hello, thanks for the reply; your solution worked well at a small scale but as soon as I had to upscale it my project became very laggy due to all the particles I needed. Is there any way of improving this?
Thanks again,
