Andy Hayes>Mixing BumpMaps with Vector Mathematics.

for SoftImage|XSI

 

level: all

 

 

As you are aware, bump maps don't blend with mixing nodes in XSI. This tutorial shows how to blend bump maps using maths nodes in the render tree.
The example scene can be found here.
This example scene uses two image maps, a checkerboard picture file (test_check) and a cell-like image (test_cell). Test_Cell has an alpha channel that fades out in a circular nature

 

When considering applying the same technique in bump map terms, we have to look at what exactly the mix node is doing. We can create bump maps in vector format, but this limits us to only being able to apply maths to these...
