Homography with softedge?

Hello

Is it possible to transform the softedge in multiscreen, like using it with homography ? In case the projectors are rotated or the surface is not flat ?

the only way i could do it is to render the multiscreen to texture then to a new renderer via drawfixed and then distort separately, doesnt work with quads

Thanks
I wanted to avoid another render pass, and use instead the spreaded transform.

I see that if I add a transform node on the Viewports, I can Scale or translate the screens independently, but not rotate or distort correctly (it only scales)

So the only way would be with DXTexture ? ?
