ID Maps for Substance Painter made in ZBrush? Is there a way??

ZBrush Usage Questions

Hi,

Really needing a way to create ID maps in ZBrush for Substance Painter by allegorithmic. I have Substance Painter and Bitmap2Material.

So watching the tutorials about Substance Painter from their YouTube channel there is that cool way to make the stitches instantly masked to put on their own layer to texture quickly. I like that but it’s because there is an ID map layer which makes that happen which looks to be another image map really.

So is there any other way to make an ID in ZBrush? If so can someone explain how?

There was one suggestion but not sure if it’s going to work. Baking textures but was suggested I just bake colors into a map to export. If anyone uses their products and have a work around to this please post. I really don’t feel like paying a bunch more money on the Substance Designer app they offer as it’s not something I’d use except to make these ID maps.

Thanks much

Richard

You pretty much just need to use polypaint to create a basic texture map. But instead of painting details, just use solid color to mask off different materials. You might paint a solid blue for rubber, a solid red for copper, a solid yellow for gold, etc.

OK. So my UV’s are already made. Here is what I came up with. You think this will work??

I imagine it would. The yellow and green are a little close in color, but SP should still be able to differentiate between them. Be sure to add some edge padding if you don’t currently have any filling up that empty space.

Thanks. Yea, I extended the edges by 5 pixels. Hope that’s enough!

I usually bump it up as high as I can to fill the space; a single mip level could wipe out most of those 5 pixels. The polycount wiki has a list of recommended padding size vs texture resolutions.

WOW… 16 pixel bleed or padding for my maps then I guess. WHEW! I guess as long as the program is reading the actual UV information there would be no chance of say a seamless tile looking wonky or creating seams with that much padding… OK. I’ll redo the UV’s and make a note of that bleed amount. Thanks for the help! :smiley:
