Our leader said that the effect I did is not like the original picture,but i don't know where the problem is

This is the rendering

This is the playground https://playground.babylonjs.com/#609BJS#12

Is it because I have not used these pictures? like this


I’m not sure what point you’re asking about, it’s probably your teamleader which have the answer to your questions here :slight_smile:

I wonder if my texture is wrong

The leader won’t be here

The playground does not work.

In the console from the playground

The playground is able to load images from IMGUR.

:joy: Too hard

I can open it here, there is no cross-domain problem

How to use these pictures.

playground did load eventually.

I think you are asking - using PBRMetallicRoughnessMaterial I can apply
repeatable_color_hq.png using baseTexture property
repeatable_normal_hq.png using normalTexture property
repeatable_roughness_hq.png using metallicRoughnessTexture property

which properties of PBRMetallicRoughnessMaterial can I use to apply

Unfortunately I do not know what the above textures are meant to affect.

These are the other texture properties of PBRMetallicRoughnessMaterial

from PBRMetallicRoughnessMaterial | Babylon.js Documentation

There is a full description of PBRmaterial (of which PBRMetallicRoughnessMaterial is only part) here Mastering PBR Materials | Babylon.js Documentation

OK , I want ask you I used repeatable_color_hq.png , repeatable_normal_hq.png , repeatable_roughness_hq.png Is it enough ?

Or if you were me, how would you use these pictures, in fact, I don’t know which material these pictures correspond to

I only konw use properties of PBRMetallicRoughnessMaterial like baseTexture, normalTexture, metallicRoughnessTexture,but I don’t know how to map the remaining pictures . I kown you means,but it’s difficult to me :joy:

I’m not sure I understand your problem. Maybe you need to modify the roughness of material. Your roughness texture seems to be invalid

I want to know which attributes these texture maps correspond to

you can look my playground code 65 - 75

JohnK has already linked a doc page which is useful to read, I had this one Introduction to Physically Based Rendering | Babylon.js Documentation , you have all your answer here, it’s just a matter of PBR workflow (here you do not have to use all of your textures).

OK :joy:

Actually you probably have to create an ORM texture, like in this example.

I tried to simplified a lot your playground to do some test, and I’m not able to use separate textures for roughness, metallic, and AO. https://playground.babylonjs.com/#609BJS#16
In my example I’m not able to load the AO map (but I use the roughness map as metallic texture, 'cause this material isn’t metallic so we can bypass metallicTexture informations)


(actually I was wrong, in my playground I could use the AO map, by putting it on ambientTexture channel, but not useful here 'cause its all white :smiley: https://playground.babylonjs.com/#609BJS#17 )

Thank you very much, It’s very important for me, I will look carefully :heart:
