Cannot render jit.gl.text3d text on top of sketch and texture
In my application I have some objects drawn using sketch and some textures rendered using "quads" I wanted to place some text on top of all that.
I have set the z order properly but I cannot get the text rendered on top of sketch or texture.
Can anyone provide some help?

I have seen posts saying this can be rectified by setting automatic and z order
I think I have done it properly. But it is not working …
