Hello, I have an 8x8 km world and landscape divided into tiles (256x256, 1024 tiles). Also when I installed the world I transferred Heatmaps (also 256x256, for 8 materials in total, inside M_Landscape i using _D _N _R _AO maps).
In ue4 it worked fine, in ue5 it causes problems.
When blending all maps of 8 materials in M_Landscape, they simply do not appear on Landscape.
If same blending with only _D maps - everything is displayed correctly. But if I connect a pair of _D _N blends, the material stops being displayed on landscape. Same with other pairs (_N _R or _AO _R etc.
I found that if I include blending maps of 3 materials in M_Landscape (including _D _N _R _AO) - everything is displayed correctly. But if you connect maps of 4 material - everything stops being displayed.
Just tried another technique - use unsplited Heatmaps (8k for each material). The result is exactly the same. It turns out it’s not heatmaps.
Add. - if i connecting only _D maps - blending fine, also painting tool works. If to connect _D _N - materials not displaying, painting tool also not working.
Add. - I decided to change all textures of all materials to vector colors - works well for all 8 materials. If i blend textures _D in the “base color” and _N _R _AO in vector colors - everything also works.
Blending _D and _N as textures still failed =/
Add. - if i do opposite - connecting 8 _N maps textures and 8 vector colors as “Base color” - all works. Is it some _D _N textures overlay problem?
Add. Blending maps thruogh material attributes nodes giving same results. More then 3 blended materials = not displaying. Still looking for an answer to this…
So, as I understand it, ue5 does not support mixing more than 3 Heatmaps, so when creating a landscape in an external program, I must limit myself to only 3 materials in advance, so as not to get the result as in the pictures above =/
Then another question arises - will I be able to use 3 materials with heatmaps and other materials for painting by hand in ue5 landscape editor? Will it be well blended?
Just checked. - yes, UE5 follows by it’s heatmaps blending rule - 50% for layer 1, 30% for layer 2, 20% for layer 3.
If it will be layer 4 and more - with heatmaps - just not display anything, also don’t display mannualy painted.,
If it 3 and less layers with heatmaps - everything works, also manual paint…
