Hi Matt,
I wanted to render out a vector displacement map for the terrain for the tutorial I'd been making.
I had two Otrthographic cameras setup, one that covered the whole terrain - 8000 ortho width and another to sample a smaller region at 500 ortho width.
The 8000 version looks good, but the smaller region vector map is very aliased when using for displacement in Maya
[attach=1]
tried a few options, moving the camera closer to terrain, higher detail (4!), and various resolutions (up to 8k)
widening the ortho width and it gets better
I know the OpenExr output is 16bit and the aliasing is worse on smoother areas of the terrain (where you'd need 32bit float to sample gradient) but is there a limit on how small an area you can sample with the Displacement shader to vector?
