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,

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.

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!
