It is common in real-time graphics to use tiling textures to represent large surface areas. However, repetition (on the left image) is noticeable .<\/p>\n\n\n\n

For example, you have a landscape and want to cover it with grass, rock, sand, etc., textures types, of course, direct painting over UV-ed mesh is a bad idea there; huge textures will be required.
Putting tiled texture is a bad idea as well; tiling is well visible, and the edge between different textures is visible too. Factures are a good solution for this.<\/p>\n\n\n\n

Using hex tiling<\/strong> allows us to hide the repetition but requires a solution to hide the seams between adjacent hex tiles.<\/p>\n\n\n

This is what we have in factures for years. Not Hexagon, but the more irregular figure for better tile-killing.<\/p>\n<\/blockquote>\n\n\n\n

Factures and vertex painting are different methods of applying detail to a model<\/h3>\n\n\n\n
\n\n\n\n

Factures allow you to apply textures without UVs<\/em>, similar to vertex painting, but with textures instead of just colors.
When you export a model with factures, you are exporting the texture information applied to the vertices, which is different from exporting vertex colors. <\/p>\n\n\n\n

Vertex painting involves assigning colors directly to the vertices, while factures involve applying textures to the vertices<\/em>.
So, exporting factures is not the same as exporting vertex painting, as they involve different types of data: it is per-vertex texturing<\/em>. <\/p>\n\n\n\n

UV coordinate is assigned to vertex, and textures are assigned per vertex as well; if different vertices have different textures, they will be blended between each other, and no seams will appear.<\/p>\n\n\n\n

Working with Factures<\/h3>\n\n\n\n
\n\n\n\n

Factures provide an easy and powerful way to achieve surface detailing of practically unlimited levels.
This is the way to apply a texture without the actual UV assignment. It works similarly to vertex painting; however, you paint with texture, not just the color.<\/p>\n\n\n\n

\n

Factures are only supported with sculpting in surface mode.<\/p>\n<\/blockquote>\n\n\n\n

The main rule is that you can assign a texture and a color to each vertex.
Each vertex on every layer has only ONE texture.
So, if you paint with texture over another texture on the current layer, the texture will be replaced, not blended.<\/p>\n\n\n\n

But you can apply many textures to each vertex using multiple layers with opacity. <\/em><\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n

If neighboring vertices have different textures, the textures will be blended between the vertices, and no seam will appear.
Pay attention to the Roads tool: it paints strips of textures, just like building roads.<\/p>\n\n\n\n

\n

If you want to use the Conditions drop list, first use Calculate menu to create or update cavity or occlusion layers.<\/p>\n<\/blockquote>\n\n\n\n

<\/p>\n\n\n\n

But there are several problems<\/h3>\n\n\n\n
\n\n\n\n

1) Export: Engine\/3d-package should support per-vertex color\/alpha channel to use FBX exported from Coat. Usually need to set up nodes to use exported results correctly.<\/p>\n\n\n\n

2) Still unfinished a bit. No good textures and no default library of textures. No shaders included. I will include shaders in the next build.<\/p>\n\n\n\n

You also can import Quixel materials as Vertex Textures for Factures.<\/p>\n\n\n\n
