Visual Issues when rendering gaps in the Terrain under GLES2 in Android devices
ozzr opened this issue · comments
If you add masks to the terrain to create a Cave or a Gap, under GLES2 on Android, it gives the below visual issue
This only happens with "certain camera angles only" (look below) here the camera is rotated just a few degrees and the effects disappear
The error is caused by setting VERTEX /= 0.0; in the vertex shader. Using discard in the fragment shader fixes the issue.
Adding a warning inside the generated shader to warn the user about this problem.
