Change TextureType of an downloaded texture

Question

Hi!

Is there a way to change the TextureType of a downloaded Texture to Image/Texture (default is GUI)?

Its easy doing that on a texture imported on the resource folder.. But with an downloaded texture?

Please help

No. There is no reason to either. Textures do not have Texture Types. TextureImporters have Texture Types which do nothing more than tell Unity how to package the image.

If you really want to set your texturetype then you will have to put the asset into an asset bundle, download the bundle, then load the texture from it.

So how do you explain this? The image on the left is with texture type set to texture. The image on the right is with texture type set to GUI.

I'll bet the image on the left has different texture properties than the image on the right. Right image looks like 16-bit truecolor and the image on the left looks like a mipmap. All of these are things you can set when creating a texture at runtime.

When you send your WWW call, unity isn't creating any textures until you try to get them from the WWW. You're not downloading a unity asset, you are downloading a file containing image information. When you set the texture type in the editor, you are telling unity what parameters to pass into this function http://docs.unity3d.com/ScriptReference/Texture2D-ctor.html

When you download the image from the internet, you must do it yourself.

The only difference is the Texture Type, nothing else. The image is already on resource folder. I change texture type, apply changes and this is what is made.

I can change texture format, but the problem that i have is texture type. When i download a texture i can´t change it.. Not even with OnPostprocessTexture function. That function is only with textures added manualy.

I think i have to use asset bundles..
