Author Topic: searching for the right setup in substance designer 4.5.2  (Read 2973 times)


i got an house mesh, which i would like to texture with an substance in ue4.

but i got an problem, to find the right settings in substance designer 4.5.2. to see all my tex-parts
in the 3d-viewport correctly:

here is my workflow

- i made an diffuse map and an specularity map (both in 4k).
- i made an new substance based on the physically based (specular/glossiness)-template
- i connected my slots with my textures
- i went to the 3d-viewport, chosed the cube and materials/default/shader/physically based
- i right-clicked in the graph and chosed "view outputs in 3d"
- the texture appears in the 3d-viewport...

but unfortunately the specularity int the windows of the house (which i made in my spec-tex)
is not shown at all....

where is my fault?

thank you very much for an answer!

Hi loopon,

If you want to fit with UE4 PBR workflow, you need to use the "Physically Based (metallic/roughness)" template when you create a Substance.

What you'll need in Substance Designer is "Base color", "Roughness" and "Metallic" outputs.

To sum up:
- "physically_based" shader is dedicated to PBR Metallic/Roughness. It will use the "Base Color", "Metallic" and "Roughness" outputs (and some others as AO, Normal, etc.).
- "physically_specular_glossiness" shader is dedicated to PBR Specular/Glossiness. It will use the "Diffuse", "Specular" and "Glossiness" outputs (and some others as the previous one).
- "relief" shader use a classic (non-PBR) workflow.

You can check what kind of textures the shader use by clicking on Materials=>Default=>Channels.
