I have made the same things that are on the palm trees demo and the transparency does not work on my object( or better the transparency works but the object is black), it was working like 1 month ago but I don't know what changed, the object appear to be black, no texture is applied, if I check the texture is present in the folder and the path is correct, so I don't know what could cause this.

this is the code I use to load the effect:



this is the code I use for the object:





If was a path problem the other textures and effects would not load, so I can't really understand why my object is black

It's a different problem, with a different shader, that time I was just using a single shader, the texture appeared but was dark, almost black.

Now I am using the advanced lighting which uses a different shader, the object is completely black, transparent but black, the same issue that happens when you don't texture properly a model in the advanced lighting, but in the palm trees example there was just a texture to be used on the stage 1, nothing else, and that is what I am doing.

Also it was a different type of transparency, that time I needed to get out the black parts so that the flowers are rendered correctly, now I am using a tent and the purpose is just to see through it like in real life, there are no parts that need to be clipped.

Ah I see, if the same code works when using different objects/textures then the first thing I would check is that the object's vertex normals and uv coordinates exist and are intact.

Testing with a normalmap.fx it works (texturing stages 0,1 and 2), obviously that shader has no transparency, but at least I know it's not a problem of the texture loaded, the texture is there.

I had similar issue with the tree/leaf shader, using models exported from blender. From what I could tell it looked like the model data blender produced was the issue, it adds an extra root frame that messes with the limb structure that the shader appears to expect.

I was going to look at modifying the python export script but have not gotten around to it. I've just been using the normal normalmap_clip.fx for now
