how to draw a colum only use one draw call?would it be better to draw multiple colunm and row in one draw?

this project is an amazing works!
but what confuse me is that you use only draw call to draw a whole column,
i assume it's beacause you use tex2d in position shader,but i tired in my own custom shader,it did'nt work. i use a noise textrue,but it only make my mesh's vertexs get a random diplacement effect, can't draw mutiple meshes.

so just a thought of me ,now you use single draw to drwa mutiple mesh , what if you draw mutile column and rows,would it be better?

and a little advice , use sepreate size variables for the debug textrue, in some case the debug shader could be very small on screen, so you can scale it like this
void OnGUI() { if (_debug && Event.current.type.Equals(EventType.Repaint)) { if (_debugMaterial && _positionBuffer && _rotationBuffer && _scaleBuffer) { var rect = new Rect(0, 0, _debugcolumns, _debugrows); Graphics.DrawTexture(rect, _positionBuffer, _debugMaterial); rect.y += _debugrows; Graphics.DrawTexture(rect, _rotationBuffer, _debugMaterial); rect.y += _debugrows; Graphics.DrawTexture(rect, _scaleBuffer, _debugMaterial); } } }

` void OnGUI()

    {
        if (_debug && Event.current.type.Equals(EventType.Repaint))
        {
            if (_debugMaterial && _positionBuffer && _rotationBuffer && _scaleBuffer)
            {
                var rect = new Rect(0, 0, _debugcolumns, _debugrows);
                Graphics.DrawTexture(rect, _positionBuffer, _debugMaterial);
                rect.y += _debugrows;
                Graphics.DrawTexture(rect, _rotationBuffer, _debugMaterial);
                rect.y += _debugrows;
                Graphics.DrawTexture(rect, _scaleBuffer, _debugMaterial);
            }
        }
    }`

Yes, it might be better if it's done with a single draw call. However, it will introduce extra complexity and instability to the code. I didn't have enough time for tackling it, so abandoned that idea.
