I want to render an openGL scene made in lua to a texture however trying to include a jit.gl.gridshape object in this is proving to be much harder than I thought producing the following errors

jit.gl.texture: error binding readback mechanism for capture: GL Error: Stack overflow

ob3d_draw_end popmatrix: GL Error: Stack underflow

I have a feeling that the answer is really simple but I can't get it.

I've included some code in the hope that it helps.

"mytexy" is the texture I'm trying to render to.

any help would be soooo soo greatly appreciated

sphereTwo = jit.new("jit.gl.gridshape", "vizualz")

"vizualz" is the pwindow name
"mytexy" is the texture I'm trying to render to.

--sphere
sphereTwo = jit.new("jit.gl.gridshape", "vizualz")
sphereTwo.automatic = 0
sphereTwo.scale = {0.2, 0.2, 0.2}
sphereTwo.dim = {35, 35}
sphereTwo.color ={1., 0., 0., 0.4}
sphereTwo.depth_enable = 0
sphereTwo.blend_enable = 1

function draw()
    jit.gl.begincapture("mytexy", 0)
    --other drawing stuff
    sphereTwo:draw()
    jit.gl.endcapture("mytexy", 0)
end

Hi, you can't use the draw function within capture because it interferes with which textures are bound for capture. I'll see about fixing this for the next release (planned for early may!). For now, use drawraw as so:

sphereTwo = jit.new("jit.gl.gridshape", this.drawto)

    gl.BlendFunc("SRC_ALPHA", "DST_ALPHA")

        gl.Color(1., 0., 0., 0.4)
