CONVERTING PBR Material Workflows! Diffuse to Color! Specular to Metalness!

NOTE: This will FIX black metals in whatever software you are using! This is a common issue in Lumion since it thinks the diffuse map is a color map. This tutorial will fix your issue :)
This is a quick video I wanted to make up so people have a better of how to manipulate the maps you get with textures or models. Understanding this is great for not only creating what you need to fix a scene but also to understand how the maps interact and give yourself more knowledge about the tools you are using!
This video goes over how to create color, metalness, roughness, diffuse, reflection, glossiness, opacity, and transparancy maps. I did not go over how to make an IOR map but to my knowledge you can just take a metalness map and make the white parts grey and you have one!

this is the best video ive seen on youtube today. thank you.

[@MBearr1221]

One thing I'd like to point out that can help in remembering when to use white/black on a map.
I think of white areas as YES and black areas as NO. So for a metal map - is the underlying area a metal? Yes? White. If it isn't, then it gets painted black.
This also applies to opacity/transparency/roughness/glossiness/specular.
Like with the metal map, white is going to represent what the map is called. So for opacity, areas that are opaque will be white. For transparency maps, areas that are see-through will be white instead - the inverse of the opacity map as you said. Same goes for glossiness, specular, roughness, etc.

thanks ,it is good for UE4

[@LuminousLabs]

Yes! If you go from 3ds max to unreal it can help. I am not sure if datasmith does it automatically or not.

[@charlesberkley3460]

Yes, this video was very insightful, do you have any recommendations for software that do great image upscaleing/low res to hi res for textures?

[@LuminousLabs]

There is actually a website I use called bigjpg I think it’s called. I typically only use it for taking marble textures from suppliers websites. I find it works well! I think there is a 20-30 monthly limit but it is free!

[@LuminousLabs]

I personally only like to 2x the width and length, so a 1k I would only go to 2k and 2k I’d only go to 4K.

Flipping the green channel is for whether or not the engine uses DirectX or OpenGL normal maps.

[@AeleksDesigns]

On the Topic of inverting the Green Channel of a Normal Map ... this is very important (and nessesary) when using OpenGL Normal Maps (for/from Blender for instance) in DirectX Applications (like Unreal) ... or the other way around ... the green channel of the Normal Map needs to be flipped/inverted when switching between these two rendering APIs.

[@LuminousLabs]

I have done the flipping for Unreal, but what other softwares use the DirectX normally? To me it almost seems like a coin toss that is why I always just examine it myself. Unreal has the flip green channel so I never really use it in photoshop, but I did feel it was important to mention.
Thanks for checking out the video :)

8:45 if that line doesn't make you comfortable, you can try selecting by color rather than with wand. From (0.0, 0.0, 0.0) to (19.0, 19.0, 19.0) did the trick for me in my project =)

[@LuminousLabs]

I will definitely try this out. Thank you very much! I normally just do enough photoshop to get by and I don't know a lot of tricks.

[@kostyarikx9754]

@@LuminousLabs cool =) all those are quite try-and-see experience =)

[@vekuhudesign7382]

Converting PBR material in photoshop I got that part, the explanation is clear.
But when you said this will fix black metals. I didn't get this part.
Please let me know if you have any related videos on this?
I really want to see it and clear my doubt.

[@LuminousLabs]

Have you ever tried to import a model with metal on it and all of the metallic parts are just black?

[@LuminousLabs]

I think in Part 4 of my metal tutorial series I show an example

[@vekuhudesign7382]

@@LuminousLabs oh! yes, I go it, Thank you.

[@vekuhudesign7382]

​Not yet, I'm not able to find free models in Polygons. I want to try it and see them.
If it's possible can you please share the model?
