First off thank you for your work, it’s much appreciated.
I tried for a long while to solve the pixel jitter but gave up since the Orthographic renderer was so bad before the 5.3 update. I used parts of your code (a fixed top down camera, 45°, no zoom/rotation) and migrated to 5.5.2 without any issues.
I do however have a question. Setting the camera nearer, in my case 1500u, allows for good shadow details and sw lumen to run with good performance.
This however introduces clipping.
I can adjust the camera near plane clipping to a negative value and avoid mesh and shadow clipping.
But when rendering trough the scene capture component no changes I make to clipping plane settings makes any difference. The near clipping plane stays fixed and all meshes and shadows gets clipped when moving along the X-axis far enough.
Have you had any luck with this?
The simple solution is of course to raise the camera and lose shadow details and lumen not rendering well. I feel this should be easily fixable since it works on the camera.
