Eae galera como posso fazer texturas mais realistas ou deixá-las mais realistas? Se alguém tiver algum tutorial ou livro ou qualquer coisa por favor me indique, desde já obrigado.
(hopefully this translation is right ^^)
It depdens on what exactly you mean → you can achieve realistic looking textures with taking a photo from something in the real world. e.g for my grass I took a photo from some grass blades - edited them in photoshop (alpha channel, duplicated some of them,…) - used them on my mesh.
In the UE4 you can also add some “realistic” effects → e.g tessellation, parallax shading, reflections,…
Here you can download some good textures: http://www.cgtextures.com/ + also take a look at them to see how they were made
Btw, next time please post your question into the “Brazil” section of the forum, because in this section you should write on english
