Title: Circular Mesh material
Post by: silvinai on March 28, 2011, 09:29:06 AM
I need to make a similar material but instead of circular holes I have a particular pattern. My problem is that I understand that I need a texture map but I don't understand how to applied . I see edit material option but I don't understand the options and in the training of the website the wireframe materials is not there yet.

So how a make an alpha map? Where I load my texture and where I load the alpha map?

I'm quite lost in this matter and looking for some tutorial.
Thanks!

The only material that supports alpha in textures right now is the general material. You will need to put the alpha channel into the image itself, or make the areas that are supposed to be transparent black.
