Interface description
Common border allows you to control all four sides by a single parameter. If it’s off you can control sides separately.
Border controls how many cut texture to construct borders part. For example, 20% grab 40% of texture whole width to create borders and left 60% as a central part.
You can get size of some container, just like in “TextBG” standard plugin.
Magnifier corrects size to shrink or stretch this texture. E.g. that way you can increase/decrease shadow size.
Theory
Imagine, you need to create nice looking shadows for a plane. You are just creating a texture faking shadows effect. If you know the size in advance — all is ok. But what to do if you are creating some customizable effect? You can't know what size the rectangle will have. 9 part texture rescue you!
1. Lets start from painting square texture of shadow effect.
2. Understand how to slice it.
Center is too big. Actually it can be 1x1 pixel. I leave this non optimal version for clarity.
3. How it sctreched?
Simple one rectangle take this result:
If we are applied "9 part" concept, we can get this:
We just change size of only three parts. It's the central row.
This way you can create a glow, shadow and frame effects, etc:
Practice
I wrote the script to provide solution "9 part texture" in vizrt.
How to use it:
- Drop script to some container
- Click "Create base planes" for creating nine sub-containers.
- Drop texture to all nine sub-containers.
- Set "Source of size", position...
- Set "Border" parameter correspondently to texture style:
There is an issue when a central row or column is too small. This is texture filtering. The issue can be solved by setup maximum Anisotropic Filter on all nine textures:
Try it yourself
I've prepared some textures for you ;)
I use white color for easy changing color in vizrt. Just add a material ;) If you want black color on a shadow, just add black material on the master container:
Glow/shadow
Frames
