Alpha Channel

[jcastillo]

Hi Juanjo.
I have a problem.
I need to render a sequence in alpha channel and can not see the results.
Manually with F9 I get to see the Alpha and save.
But with me F10 saves the image but not alpha channel is a normal render.

I have activated the alpha channel in the kernel.
but I do not know that more than I do.

Thank you

How are you saving the images, using the LW image saving functions or from the render passes node?

Anyway in theory if you save the images using the LW image saving functions using an image format with alpha channel support (TIFF32 or TGA32 for example) the alpha channel should be there.

Thanks,

Hello, again.
I use to save the images, the image saving of lightwave .
I tried to save the alpha channel tiff i TGA32 .
as usual ... save it as a normal render.
but in the viewer render lightwave once finished, if I select alpha , if the alpha channel is .
I can save the image manually as I have always done.
but now I have to manually calculate and 1500 frames ...

Weird. I'm just testing now a scene here, saving the image as TGA32 and the alpha channel is in the file, as you can see in the attached image.

Can you send me a scene with this problem?

Thanks,
