Hi People of Poly count !:) I'm going to be creating a thread where it will be containing my photographic realistic textures and hopefully can gain some good feedback of you guys

Please don't use PNGs. Your 3MB source files (which are excessive to begin with!) turned into 16mb and 35mb files when they were attached. More info about PNGs here in the sticky Information About Polycount & New Member Introductions.

About the texture, wallpaper doesn't need a normal map, nor ao, nor height. Those are excessive for the end result. All you need are albedo and specular/roughness. But maybe this is a template for multiple texture types?

Also you may run afoul of copyright restrictions if you're photographing someone else's artwork. The pattern is owned by some wallpaper company somewhere, who could conceivably find your textures with a reverse image search of their pattern.

ok thanks for all the information, yeah I agree I think a normal isnt need with a wallpaper as its flat . il upload some smaller files now.

These are neat.

I think the red brick could be tiled better, it has repeated patterns inside, so it looks like it's tiled 2x2 instead of unique. It's super obvious with the height map.

PaulEvans92

thanks, yeah I shrunk it down but il think il go back and change that, only issue i'm really having at the moment is where to insert the height map in unreal as ive been told different things.

Hello. How are you removing the lighting from the original photo?

PaulEvans92

Sometimes I darken some parts of the image, bud the other main method I use for bricks is I first make the whole thing seamless, I then find the bricks with to much light source and I then replace those with the dark bricks by using the rectangle marquee tool, so using this tool I individual replace each brick which is not suitable for the texture hope that helps !

That's interesting. I remember reading something about using (in Photoshop) the High-Pass filter (Filters->Other->High Pass).
First you make a copy of the photo, set its blend mode to Color, then on the copy below you apply the High Pass filter and merge the two.
That should remove the lighting and keep the colour information, but I'm not sure if it works for every case. A rock photo, for example, would probably lose a lot of detail.

well i went out the other day and took alot of photos of different bricks and people looked at me like I was mad haha! but il try out that method with the one il be working on today and il post a picture of the results of the method !

Hey RN sorry for the very late reply Itried out your method and it works it does take away alot of the lighting issue, but like you said it does remove some detail of the bricks, here is a wip of brick texture using your helpful method thanks again ! its always nice learning something new

My Glass material created in unreal engine 

Eric Chadwick

Not very realistic glass. Are you looking at photo reference when making these? 

For example, searching for "glass ball":

PaulEvans92

this was a tutorial I followed using the material editor in unreal think I may need to play with the settings now seeing the image 

Eric Chadwick

Always use reference! Tutorials typically only give you technical info.
