Refraction Tutorial (ZScript)

[WingedOne]

Here's a little ZScript tutorial I put together demonstrating Refraction.

Just a few tips to help all of you out with refractions:

1) Refraction is polygon-based. The more polygons your model has, the better the quality of the refraction that you will get through it. You can increase the polygon count through either the Tool>Modifiers>Initialize settings or through Tool>Modifiers>Deformation>Divide before snapshotting the model to the canvas.

2) Refraction will only work with the current layer. Objects on other layers will not be seen.

3) Refraction will only show unshaded RGB colors. In other words, material-generated color will not be seen through the refractive object. It is therefore recommended that you set your lighting and bake the layer before drawing a refractive object.

4) Don't forget that you can set positive and negative refractive values. Positive values give results similar to a farsighted person's glasses -- they have a magnifying effect. Negative values would be a myopic person's lenses, having a minimizing effect.

Have fun!

I commented out a line in this ZScript so it will run in ZBrush 2.
