Alright, I've managed to get the forest tiling test working seamlessly and looking good; which means an infinite forest is possible.
(Though likely you won't make it that far being so reckless)
All this is actually room tiles, not a single piece of terrain; here below I highlight select a few tiles including those that handle the path and it's blending textures. (You can even see the test player wireframe and camera too).
This isn't final yet, all we need now is concrete wall + door generation, a few more 'other' tiles, tree leaves, stumps, random foliage and a finished monster, shouldn't be too hard. :mrgreen:
Everything looking proportional? Path too wide/small? Tree's too tall/thin? (This fog is using a slight cloud texture to it too to help add to the mist). I'll add a few more tree variations too, right now these are all the same exact model, just rotated at different random vectors slightly, I'm also looking to improve the transition of the low poly tree to the ground, perhaps with some slight dirt mounds or something. :S
Edit:
It's really high-poly in the picture right now because I built a scene that's almost 2/3rds bigger than the image render picture I posted above, as well the ground tiles haven't been cut down poly wise yet, landing the final poly count around 12-15k at the end hopefully at any given time.
Also if anyone wants to help edit the textures in the scene to match the articles original color scheme, I've posted them here:

Send them back to me when your done and I can post test renders.
