Grid Alpha

[Gman]

Does anyone have an example or any idea how I can used an image as a texture with a alpha channel so that the render will let the light through the image? Say like I have a grid type image with alpha that i want to use on a cylinder so it looks like mesh and the objects inside can be see through the grid or fake wire mesh created by the image?

Not sure if that explains what I wish to do.

Hi Sarford,

What you're talking about is described in the XSI Guides:

Texturing > Maps, Maps, Maps > Creating a Transparency Map

Hope that helps,

If you have lots of overlapping objects with transparency-map, you might encounter raytrace depth issues. In this case, you might want to check sprite shader.
