Hello Guys!
I am using Handles.DrawPolyLine and Handles.Label for drawing some curves and values of those curves.
At OnPreviewGUI everything work just fine.
However, when I call the same method at OnGUI, only the first Handle method is drawn, although the others are called (I have debugged that).
If I comment the first DrawPolyLine, the second DrawPolyLine is drawn.
I do not know what could be happening.
Any idea?
Using Unity 4.6.5
Thank you very much.
Sure, but I am not sure if it will help.
The main method is: DrawCurveWithXValue

Rect ranges = new Rect(minX, minY, maxX - minX, (maxY - minY));
EditorGUI.CurveField(r, curve, color, ranges);
