demostenes Posted December 22, 2014 Posted December 22, 2014 Under some conditions (probably more materials per chunk than 4) there are visible seams of terrain chunks: http://www.dropmocks.com/mHysRI Settings of materials (blending settings) does not affect it.
silent Posted December 23, 2014 Posted December 23, 2014 Hi, Could you please send us your terrain with all settings and all textures (including materials, heightmaps, masks)? I believe it is the same terrain as you wanted to send us in this topic? :)Thanks!

demostenes Posted December 23, 2014 Author Posted December 23, 2014 Hi, Could you please send us your terrain with all settings and all textures (including materials, heightmaps, masks)? I believe it is the same terrain as you wanted to send us in this topic? :) Thanks! Not exactly, I have several terrains for experimenting. Anyway I extracted both terrains. Terrains are identical, only difference is, that in first I used 6x4channel texture with masks, in second I used 21x1channel mask file. Difference is obvious, first terrain has mixed layers (it seems like during import only first channel was used), second is OK. Masks are identical, so terrains should be identical too. There are also visible seams between chunks, I ve put dummy node there. I am just uploading it on your ftp (esq.rar), it contains all files. It will be there in cca 50 minutes Btw, It is quite a lot of work to extract it from project to some compact form (I ve gave up and recreated everything manually again), what about some export feature, which will export node+all relevant files (something like Unity3D does)? Edit: upload finished

sebastianbah Posted December 24, 2014 Posted December 24, 2014 Hi,I'm afraid it's a problem with a normalmap import.We've added this issue to our internal bug tracker. Thanks for your test sample.
sebastianbah Posted January 22, 2015 Posted January 22, 2015 Improvements for this problem will be available in next SDK release.Seams can still appear with a low resolution refined normal maps, but there should be no problem if refined texture size is 512 and over.

How big is performance impact? 512 is quite a lot for one chunk, we are usually using 256 for normal maps.
sebastianbah Posted January 26, 2015 Posted January 26, 2015 I'm afraid it may depend on a project. Also you may try to use Landscape plugin to use multiple terrains instead of a big one. You can check the result in PortAngeles and California demo. In these demos refined normal map size is set to 256.
