Substrate gives me these weird dots when using color map on automotive materials

Hi everyone,

I’m currently working on a project and wanted to use substance. I’m using the automotive materials pack and tried to input a texture I created in Substance Painter into a couple of the materials to see how the livery of a car would look in it. These weird dots just keep showing up in each of them and I definitely can’t use that. Any ideas as to what can cause this issue or if it’s a project setting I need to enable? The textures are 2K idk if making them 4K would help or not.

Thanks in advance!

Hi @Los_Uberos , could you please answer a few follow up questions so that I can have a better idea of what could be the problem?

  • When you open the material instance and disable the “flakes” layer or set the intensity to zero, do the Dots disappear?
  • Did you auto convert the legacy Automotive Materials to Substrate or are you plugging your Substrate maps into a shader built natively from scratch using Substrate Slabs?
  • Could you please check to see if the Dots jitter or change pattern when you move around the camera in the viewport, if not are they completely static and baked onto the surface like a texture?
  • In your view port, on to top right hand corner in your “view Mode Settings” (by default it should be set to “Lit”). Could you please go to the Buffer Visualization sub menu and check the Base Color, Metallic and Roughness channel so we can pinpoint in which channel the dots are visible.
  • Could you expand on how is your Substance map is plugged into Substrate graph? Is the base color being driven from the bottom slab, and is the sRGB unchecked if you are using packed masks for roughness/metallic?
