How can I use multiple map types for texture on 3D objects?

[edsager]

Hello,

I am using AwesomeBump to create diffuse, specular, ambient occlusion, roughness, normal, height and metallic maps/images for 3D objects.

I want to use Photoshop to add texture to the 3D objects by creating new textures/materials in Photoshop or direct application of maps/images to the object or creating a new brush and painting or any other method.

I am stumped as to the value/usefulness of these maps/images for Photoshop use.

Is there any value to creating these maps/images?

In what ways can I use multiple such maps/images to stylize/texturize 3D objects in Photoshop?

Thank you,

Hi

Photoshop does not use a PBR Metallic/Roughness or PBR Specular/Gloss  workflow.

You might get close to an acceptable render plugging the maps as follows :

Diffuse >Diffuse

Specular >Specular

Height > Bump
Roughness > Roughness

Then tweaking the remaining properties. You could also tweak the metallic map to create a reflection - but they are not the same thing.

There is no direct input for metallic or ambient occlusion.

Adobe's 3D application - Dimension does use a PBR Metallic roughness workflow - but you would really want to output Base Color, Metallic and Roughness from your software rather than diffuse and specular
