hi list,
how do i make a pix_film with a linear gradiation transparent (from
left to right?)
thank you
max
WIth a pixel shader.

Write a pixel shader that ties the x,y pixel position to the transparency. This is easier to do left to right and top to bottom.

Hello,
As Chris says, a shader is fine, but you can also do it with older opengl stuff. like in this patch.

Thanks, cyrille. I know virtually nothing of OpenGL other than what I've learned from using Gem.
Is there any tutorial on implementing pixel shaders in Gem?

there is an exemple in the gem doc : 2.advence/18.gl_sading_language.pd this is how to load a shader with gem. for generic informations about how to write a shader, you have to find a good book. like the openGL shading Language by Randy Rost.
