I downloaded this tree model of the internet ( It is legally distributed ) and it comes with diffus, normal, opacity, specular texture for the leaves and diffus, normal, specular textures for the trunk.
How to import them properly into unity?
Here is the link to the [tree model if you want to see it for yourself](http://www.filesonic.com/file/46321531/Free Palm.zip)
That palm_tree.obj loaded fine into Unity. Drop it into your project’s Asset directory.
The textures on the other hand aren’t really usable as they are. Transparency is usually the Alpha channel of the Diffuse map.
Find some Unity shaders that support.
Leaves: Diffuse + Normal + Specular + Transparency
Bark: Diffuse + Normal + Specular
That is what i was looking for: Someone to tell me what shaders to use cause i am newbie and i don’t know my way much.
Any ideas?
The Bark would be “Bumped Specular” shader, but the specular texture would have to be added into the Diffuse’s Alpha channel.
Transparency + Specular are usually in the same channel (Diffuse Alpha) for most of the standard shaders, so that’s a problem.
Should ask in Shaders forum, someone might have one lying around.
Do i need the specular and transparency textures? If not how to apply the diffuse and normalmap textures to the leaves?
I used bumped diffuse and when i applied the normalmap texture a message appeared under it says: “This texture is not marked as a normal map” and a button next to it “Fix it”
But the tree looks like this in the game:

How to fix it?
If you want to paint your trees and have advantage of tree billboarding system, you need to have only 2 materials on the tree and use special built in tree shaders for bark and leaves.
Look at existing trees in demo asset library, it is the fastest way to learn how to do it.
Right now i just want to learn how to make this tree look right, i am still learning unity, can you please tell me to apply just the diffuse material ( with alpha channel ) to the leaves?
Please take a look to the picture in my previous reply to understand what i am talking about.
Do everything (uv maping and material assign) in your 3D modelling software and export as fbx. In unity you will see your imported mesh + empty materials. Just select texture and appropriate shader.
If you dont know, how should such textures look, look at textures from demo tree models (free assets library).
Please notice that this is a model downloaded over the internet, i gave the link i downloaded the model from in the first post.
Also please notice ( see the picture http://dl.dropbox.com/u/5217556/Tree.png ) that i assigned the texture to the model but it looks wrong as there is no alpha channel.
Please anyone with experience reply.
So again. Look at tree textures from default unity assets and check, how are they made. Yes, there is no alfa channel, so make one a put it to texture alfa channel layer.Then use proper shader in unity.
