I was hoping to see the fix in 4.13… Now delayed a few months. ---

Just as a heads up for anyone who is still sticking to 4.12. Landscape components in 4.13.1 are still going invisible if tessellation is used so you might still want to wait until it’s fixed before moving your project to newer version. ---

Just checked your project on the AnswerHub. Yep, [the](https://issues.unrealengine.com/issue/UE-35494) was marked as fixed, but apparently it is still there. And speaking about original performance complaints described in this thread, it did not get any better in 4.13. ---

The costs still seems really high even when only affecting a tiny patch near the camera and only tessellating parts of the landscape that need detail (rocks etc.) Depending on the view angle it usually halves the framerate at least. I’ve gone for creating lowpoly scatter piles to combat this problem, but would be really great to see a cheap distance based landscape tessellation fix in the future for sure 🙂 ---

It’d be nice if Epic would focus on fixing bugs and performance issues before adding new features. There was an with landscapes in the early versions of UE4 that turned an entire component black if it had a hole in it, and it wasn’t fixed until many versions later (if it ever got fixed at all, I stopped checking.) ---

@, As I see it nothing regarding landscape is fixed yet. Literally no other aspect of the game engine development right now can be more important than the landscape as 99% of the games out there need this freaking landscape to work properly and meanwhile their projects are floating in the air. Why nothing in UE4 is perfected before moving to new imperfect things such as the new contact shadows that has to be turned off in order for the foliage to look correct. Sorry I lost my temper… -\_- Because the tessellation cost was supposed to be reduced in 4.13 and then it didn’t, and 4.13 also brought us the disappearance of landscape components to make the tessellation unusable even at that high cost. And while these were on the todo for 4.14 they’re now backlogged as well… @jojo8026, Yeah we have tessellation there by default. Works perfectly fine on 4.12 and has low cost due to the way we have setup our landscapes. On 4.13 and the 4.14 preview you have to turn tessellation off. ---

Hey guys, First impression is the components disappearance bug is fixed, the tessellation huge base cost is fixed as well. LOD0 looks black sometimes though.
