Render a tileentity to imageFile?[1.8]

[ItsAMysteriousYT]

Is it possible to render a tileentity for example a trafficlight not to the screen, but to an image and then save it?

Yes.  But it will need a fair bit of knowledge on OpenGL.

 

The basic idea is to set up a framebuffer and render to that instead of to the screen, then save it to an image file. 

 

An example class which renders to a framebuffer is here

The bits you're interested in are updateTextures().  The hardest bit is positioning & rotating your TileEntity so it is the correct size within the frame.

 

The Minecraft screenshot code ScreenShotHelper is also very useful to look at.

 

I should warn you it will be pretty hard going if you haven't done much OpenGL before.
