I am trying to project on a curved surface. The surface is curved both on the x and on the y axis, in other words it is like a section of an irregular cylinder which is also bending, although just a few centimeters, vertically.
I am using 2 projectors with the Multiscreen module and the 2 projections are blending on a vertical middle line, the 2 projectors are placed side by side.
I am using the Grid Editor to map the curved surface.
Now, the vertical bending makes it so that the Multiscreen node can t get a perfect blending.
I can see a couple of solutions:
-modify the Grid Editor so that I can modify the left and the right side of the surface independently, then join the 2 renderers side by side and finally feed it to the multiscreen node
-using Elliot Woods’ spatial-edge-blend-shader which I ve tried but haven t really managed to get working
Has anybody ever faced a similar task? What s your approach?
