Textures with Alpha Channels

[randallr webforumsuser@macromedia.com]

I'm attempting to model trees in Director 3d, in order to create the appearance of lots of leaves I'm place textures of several leaves at the ends of branches. I'm placing the texture on a plane model, the alpha channel allows the white to be transparent. My problem is that I want the leaves to be visibile from both sides, however when is use

newModelResource(newModelResourceName, #plane, #both)

I can see the pink and white grid in between the leaves and slightly transparent

Setting the #facing paramter to #front or #back works, but then I can only see the leaves from one side.

To work around this I'm currently creating a group with two planes with the leaves facing #front on one facing #back to work around this, but I don't like the idea of creating two object when I should only need one. If anyone knows how to get rid of the pink and white grid, please let me knowdafsdfa

hi randy, using alpha textures is actually quite easy. there is a simple example on my site

it also explains the various problems people get. you'll find that

t.renderformat = #rgba8888

is the relevant line which makes it work

Create the plane using either #front or #back, and set the model.visibility to #both.

If you create the plane resource with facing set #both, it actually creates two planes, and each one can receive a different shader in the model.shaderlist
