I thought that the “sparse voxel octree” idea meant that if you placed a set of voxels together they would be combined into one larger one? So if you place four 1m cubes together to make a 2m x 2m x 1m shape is that still 4 separately refreshed voxels or one voxel?
I ask because I am seeing two separate problems…
ONE: I placed a flat plane on a 200m x 200m plot on the strip using the setGrass.js script from @KevinMThomas and that will place 200 x 200 x 1m voxels . I put another plane next to it, so that’s 200m x 200m x 2m and 40,000 drawn voxels, but ONE box shape. What seems to happen is that the two planes are drawn fine, but then about 40 rows (so about 8,000 of the last drawn voxels disappear after 20 seconds or so and always to exactly the same row that was last drawn. Also then if I add a voxel manually, it is drawn, but after a few seconds it disappears. Its as if a limit is set for how many voxels can be in the plot.
TWO: Although I have a very simple 2m deep green rectangle plane, when I move the avatar forward and then back, the edge of the block is redrawn quite slowly, I can see each 1m cube voxel being redrawn and it takes a few seconds. I am on a reasonably fast i7 processor Windows 8.1 system with a Nvidia GTX 680 GPU. No shadows are turned on (as that sometimes causes the voxels to not be displayed due to another reported issue).
