Hi all, so my problem is this: I have a bunch of planes snapped together, for a floor, and i want it to look like a sweet tile floor (because of the tessellation on a height map should do the trick). ![108705-tile_problem.jpg](https://d3kjluh73b9h9o.cloudfront.net/original/4X/6/f/7/6f77cf5720322c674d5ccaa9f7de73b3df98ecbf.jpeg) However, as seen on the material on the right…wtf… where are all these lame artifacts coming from… plz Gurus help me, how to fix, to remove weird artifacts. Super thanks, ---

First connect a variable to your tessellation multiplier, the higher the number you set, the higher the polycount will be, which will give you the result you are looking for. However UE4 has a cap on the tessellation multiplier, therefor you cannot tessellate the mesh enough to get the resolution you are looking for. You can tessellate your plane in your 3d modelling application. You can also consider parallax occlusion mapping, which will give you the result you are looking for: > **[A new, community-hosted Unreal Engine Wiki](https://forums.unrealengine.com/t/a-new-community-hosted-unreal-engine-wiki/141494)** > > After over a year in maintenance mode, the official Unreal Engine Wiki is now permanently offline. These resources now live on a new community-run Unreal Engine Community Wiki — ue4community.wiki! You will be able to find content from the official... However this look like a simple material, and I would recommend you would just model it instead of using a displacement. If you decide to use displacement, I would recommend you plug a map into the displacement multiplier where you can specify a high number of tessellation near the holes, and none on flat surfaces, ---

Hmm not sure what you mean by plug in map? (what kind of map), i thought the multiplier took scalars/constants… Also with a crazy large constant i was getting nothing… ![108710-tile_problem2.jpg](https://d3kjluh73b9h9o.cloudfront.net/original/4X/e/5/d/e5d1e35046a052439dfefc8b5577a070e7fdc61a.jpeg) i guess i will try the parallax technique, because i reduced my cool looking tiles to this simple example, for purposes of problem solving… ---

Like I said it has a cap, even if you put 1000, it will stay limited to 8. It takes a scalar parameter, but you can give it a one channel map, that gives it different multiplier value for each pixel. Anyway stick to the occlusion solution it will fit best this example, just don’t use it too much as it will impact your performance if you use it alot ---

Just export a more dense mesh from your modelling application. That box, tessellated by a factor of 15( which is maximum, even if you put a thousand there), would not have enough geometry to displace individual tiles. ---

Ok so i have been trying to think what you mean exactly with this… …i think where your going with this is, “make the tiles in your editor…” am i correct? ---

Trying to figure out exactly what you mean…? did you mean “make the tiles in your editor…”?
