Export a transparent png of object
Hi guys,
I need to do the following.
Add a 3d model eg tshirt. Add an logo on the front and back. Rotate the object Export an image of tshirt with logo from any angle.
I can do the first steps, is the export achievable in Unity?

Hi,
I now have a png of the whole scene using code from http://docs.unity3d.com/Documentation/ScriptReference/Texture2D.EncodeToPNG.html.
How do I get the PNG from newCamera.

I found the issue (just after posting).
I dragged the New Render Texture from the Assets/materials folder instead of from the assets folder.
What is the difference between the 2 ?

Hi there, I followed the render to a texture article. I now have 2 cameras. camera1 looks down on the scene. newCamera (with the New Render Texture assigned) looks down on the scene. I added a gameObject - cube (is this correct?) and dragged the New Render Texture onto it.
I can see the cube with camera1 and I rotate an object with a key press to update the scene at runtime.
The cube remains grey in the IDE and also at runtime.
What am I missing here please ?
Cheers

Yes that's easy enough with Pro. You need to render to a texture with the suitable camera flags turned on (clear to SolidColor, transparent I believe), then save the texture to a PNG.

For some reason solid transparent colors don't work with some projects (depends on the render pipeline maybe?) but this nutty solution of rendering 2 textures (white bg + black bg) then diffing them worked for me: https://answers.unity.com/questions/12070/capture-rendered-scene-to-png-with-background-tran.html
