How to render bufferedimage to Gui?


Recommended Posts

Use renderEngine.allocateAndSetupTexture to get a texture id for your image. You can bind it with the OpenGL texture binding methods, just don't forget to call renderEngine.resetBoundTexture after you bind it or you will mess up most of Minecraft's other rendering.

If you don't need the texture anymore use renderEngine.deleteTexture to free the memory.

It works!




but I dont know how to use opengl to bind texture with the integer allocateAndSetupTexture returned .


now I just use allocateAndSetupTexture in DrawScreen  than to draw .After that reset and delete.


I think it will  cause lag.
