Alpha brushes are an excellent technique to quickly add complex details to your 3d modal. Instead of listing a brush pack, I’m going to provide websites and packs that are free.
22 Free Sci-Fi height/alphas
The first brush packs on our site are 22 sci-fi brush packs; sci-fi is one of the most common and popular projects for most 3d artists, but there aren’t many free sci-fi alpha brushes available, so here’s your free sci-fi brush gift.
55 Ornament Brushes
Small things like Ornament aren’t difficult, but they are time-consuming, and most of us want a quick way to accomplish that look. An ornament can enhance the beauty and complexity of your scenes.
Rock Brush Library
Most nature sceneries require rocks to appear natural; rocks are not difficult to create, but details are, which is why alpha brushes are so useful for adding details.
Skin Alpha Brushes Pack
There may be times when you require skin texture in your 3d work, and while you can acquire textures from a variety of sources, most of them aren’t that realistic. That’s where this pack comes in, since it has numerous detailed skin brushes.
10 Cracks ALPHA PACK
Our world is not perfect, and without all of those flaws, worlds would appear unrealistic and bland; cracks are everywhere; some are unnoticeable, but others are, and this brush pack will come in handy for you because it contains 10 alpha brushes; however, you must first understand that commercial use requires payment.
Stylized Roof Texture
This is for people who want a Stylized Roof, so download this if you are looking for that. but first understand that this is texture not brush but this has a heightmap, so you can use that.
This is not all; we will be adding additional brush packs to this list in the future, so check back often to see the most up-to-date list.
