(Webgl2 / WebGPU support) A better outline shader than the one that already exists on the C3 addon stack exchange.
Hi, yeah this is an issue with C3's effect compositor. It doesn't provide a good way to get the size of one layout pixel unit across all scales and angles. I use an approximation that hopefully works in most use cases, but assumes that the render target and the layout are aligned which isn't true if the layout is rotated.
In fact my approximation only works at angles 0 and 180 and breaks on every other angle value, and there is no way to really fix this without also breaking the fact that the outline pixel size is tied to layout pixels.
If you want, you can modify the effect. In the code you should find a value called "texelSize" which is my approximation, and instead use C3's "pixelSize" value and it should hopefully stop stretching, and you can counter act the wrong pixel size value by using bigger width values
