Hello everyone,

This is a truly old chestnut in my experience and somewhat of a stupid question.

I am hoping to create a series of textured grids to form a 2d animation but in 3d space onto billboards.

However the same old problem of the alpha channel from photoshop not working correctly is scuppering me again.

Please help me (and others) sort this problem out once and for all.

I would really appreciate any help or links to a good tutorial.

Thankyou

cheers

chris

What do you mean the alpha is not working?
-Are you sure there is an alpha channel in the picture you're using?
-How are you using it in XSI?

Thanks
Bernard

Hi Atyss,

Thanks for your quick reply and apologies for my sluggish one.

I have been working away on a summer school with teenegers and wanted a quick and easy way to do 2D animation in XSI using the experience version.

I opted for the transparency map approach in the end.

I have not yet explored the improved texturing tools in the newer version but I am told they are a godsend.

Thanks again

chris
