Adding separate textures under BSDF

[baher3d]

I am trying to render a scene with a 3D human object. My materials are a diffuse map, a normals map, and multiple specular textures of different object parts. How can I import it into my scene? The only BSDF similar to what I need is The-Principled-Bsdf but it doesn't have a normals option and the option of adding multiple specular textures.

What I'm currently using is:

'material':
        'type': 'diffuse',
        'reflectance': {
            'type': 'bitmap',
            'filename': 'diff_texture.jpg',
            'wrap_mode': 'mirror'
        }

Hi @baher3d

The normalmap plugin can take a nested BSDF as you can see in the documentation. So, you can combine it with any BSDF really.

From your description, I'd recommend the prinipled BSDF too. I'm unsure why you have multiple specular textures? Can you not just merge them into a single one (your UVs shouldn't be overlapping)? Or split your object itself eventually?
You might even want to take a look at the blendbsdf. If its easier to create separate materials and then merge them for your shape. It would require a texture to map your "different object parts".

Hey @njroussel Thanks a lot for the fast response! The objects dataset was bought online, I'm also unsure about the logic of separating them. I think the best option is as you recommended, I will try to merge them and use the principled BSDF.

Thanks again!
