thecolclough If you render a movie to RGBA .png files select only the image channel Anim8or makes full color RGB with the appropriate alpha channel. The background (where the alpha is 0) will be whatever color it is on the screen, which you can set to any color (or an image, etc) in the Scene->Properties dialog using the Environment button.

The black background and separate alpha images are created when you select Image+Alpha Channel which outputs both channels as you'd expect. The black background makes it possible to blend the images with another image an not result in a color fringe tinted the background color. This is not possible with the back ground color which can vary when you use an image or panorama.  See the user manual for how this works:

Check out build 1124 with a few fixes and Layer support for Figure components.

Will do. That was an oversight.

neirao:

Steve, is possible in next builds EXPORT IMAGES /IMAGES SEQUENCE to .PNG
WITH TRANSPARENCY PIXELS EMBED in the png files??

Yes, this will work in the next build. All you need to do is check the RGBA box (which is the default) and select the .png format. Somebody in the Anim8or Software Department forgot to pass that information from the movie rendering code to the image saving code.

I don't want to use SW acceleration. HW acceleration is always better. 99% of today's Windows computers support it in some form for WinXP and later, more like 100% for Vista and beyond. Trevor is using Win98 in a way that Microsoft never supported. The 9700 Pro's support of dual monitors is a testament to a lot of work by ATI (and I'm an NVIDIA fan so I don't say something nice about ATI without a good reason ).

cooldude234: There are two ways to utilize transparency in textures.

1. For a RGBA diffuse texture you can use it as the diffuse texture and set the Alpha Mode to Final. This will use the RGB components for the diffuse color and the A component for transparency. By using both a diffuse color and a diffuse RGBA texture you can achieve 9 different effects. The most useful is Blend Mode = Decal and Alpha Mode = Final which is what I think that you want here. See http://www.anim8or.com/smf/index.php/topic,4985.msg36548.html#msg36548.

2. If you don't have an RGBA texture or don't want to use a texture for the diffuse color, you can use a Transparency texture. If there is a diffuse texture, set it's Alpha Mode to None. Then add a Transparency texture. The RGB components will be averaged for the alpha value.

Note: You can set the diffuse texture's alpha mode to something other than None when you have a transparent texture as well to achieve other effects but they aren't really that different or useful and can be inconsistent between renderers (though I may someday come up with some useful additional combinations and support them consistently through).

Raxx: You can do this by setting the diffuse texture's alpha mode to "Final".

When loaded as a texture, could there maybe be a check box in the Texture Mode Selector dialog to apply the PNG alpha to that channel?

Fantastic! It was just a little copy-and-paste error that pasted the wrong OpenGL function. Darn you, copy-and-paste! :-)
