I did some tests with TURTLE vs xNormal the other day. As much as I want to like TURTLE it just doesn’t hold up when it comes to the quality of xNormals AO bake. The normal maps are pretty similar so that there is pretty much no difference. But the AO has numerous issues, ranging from the max color value not being represented where it should be, to it ruining a tiling sculpt because it seems to have a very slight gradient color change from left to right giving you a seam between tiles.
Where TURTLE excels is in bake time. About 2 minutes to bake a 2k normal and AO map is pretty impressive, and if I were making something that tiled would be pretty acceptable. I could always go in and play with levels and such in photoshop to fix the max color value of the AO, but fixing a subtle color change is more work than I want to do for a subpar bake.
xNormal on the other hand took close to half an hour, but the bake was excellent.
Another method, the one I ended up going with, was to bake my information in Substance Designer. I ended up getting a similar quality bake in the AO but with different details emphasised (the normal map wasn’t half bad either but I prefer the one created by xNormal or even Turtle for what I needed). I then took my bake from SD and multiplied it over the one from xNormal. This allowed the quality of both The bake times were similar to that of xNormal, so I wouldn’t suggest this method for quick work since it is close to an hour.
At this point you have a good base for your texture work. I will be updating some of that on Wednesday most likely. I need to go in and compile screenshots.
