Where or how can I get a roughness input in to the Base Material as It Does Not Exist?

Hello,

 

I am in the process of making a ceramic material, and I do not see a roughness map input on the true/false input dialogue.

 

Please advise on how to add a roughness map to my basic material?

 

In addition, I want this material above to be able to adjust sizes for typical input of photos and I am not sure if I should use the Bitmap to material light or the basic material.  Please note there are a slew of inputs not available in the Bitmap to Material Light?  If this is a better way to go then I would also like to know how to add the input roughness, etc..., to the Bitmap to material light map?

 

Plan is to make a template for different ceramic typ material sizes like 2x2, 4x4 8x8 4 x 16 etc..., and use photos for the patterns as the inputs with the ability to change the size of the tile to fit the photo.  I know I can do this in sampler and I prefer to use SD.  Basically, the size of the tile will be the size of the image of the ceramic tile, and I understand if it needs to be a square that I will need to use a transform to get the pattern on to the tile correctly.

 

Thanks in advance,

You are using the Specular - Glossiness workflow, that's why there is no roughness input. You can either change the workflow or you use the Glossiness - Input since it's just an inverted roughness map.

I hope this helps.

Stay healthy and creative Marco

    Hi,

    Thank you so much for fast response.  It's been quite some time since I have been in Substance Designer, and I did find it after added another base material to my practice template and saw it there - then realizing I must have made that mistake.

     

    Thanks again!

      Hello,

       

      Thank you for reaching out!

       

      Make sure the 'PBR Workflow' parameter of the 'Base Material' node is set to 'Metal - Roughness'. This is required for displaying the 'Roughness' controls.

       

      Regarding the ideal setup for your workflow, it will likely involve using Input nodes in a graph in order to feed any bitmap into that graph for processing.

       

      If you have images that can illustrate what you aim to do, I can provide more accurate and detailed guidance. I am unsure I understand how the photos will used and the type of material you wish to produce.

       

      Best regards.
