OK. In the Material>Details>Material Expression Texture Sample… I changed “From texture asset” to “Shared : wrap” and it decreased the number of Texture Samplers; from 9/16 to 6/16 (This, using a grayscale texture + 4 Normal maps).
¿Is there any disadvantage or drawback using the “Shared : wrap”(up to 128 textures)?
I dont know why people refered to “16 Texture Samplers limit” isue. A readed tutorials over internet and all of them uses max 4-5 textures .
Then, I readed from the next link that is related to OPENGL 16 textures limit max(it refers to mobile games).
We are newbies with this engine, but our team is focusing the game to PC/PS4/XOne platforms.
I need to filter grayscales and then apply all together linked to the “Base Color”. ¡But not blended! For the moment I got it using the node “Landscape Layer Blend”(LB Height Blend).
I send you the materials *.uasset (remove the .txt extension at end) .
