How to add texture to my dae file without transparency.

Hello.

I create dae file on Blender. In Blender, leaves are not transparent. However, in gazebo, leaves have transparency.

If I turned off transparent view, I got the last picture, but I want to add transparency to black area.
How do I insert leaves in gazebo as in Blender.

Hi,

You'll want your transparency map stored in the alpha channel but you don't want to save the file as a transparent image. A good plugin for this for photoshop is SuperPNG. You'll see a dialog like this and you'll want to make sure "Alpha" is checked.

you can take a look at the oak_tree model as example: https://github.com/osrf/gazebo_models/tree/master/oak_tree

It uses a material with a pass that sets the alpha_rejection param: https://github.com/osrf/gazebo_models/blob/master/oak_tree/materials/scripts/oak_tree.material#L9
