weird artifacts when baking a texture
I just finished modeling this table also setup vertex color made sure everything is correct, i then export it to adobe Substance Painter but when i beak textures it has weird artifacts ID maps and I tired to texture it but it doesn't work can anyone please help

Screenshot of your UVs?
here is my uv map and also the model
Those UVs will not work for baking and texturing in Painter (or any texturing program).
Most importantly, ensure no overlapping UVs per texture set (offset duplicate geometrys UVs to avoid errors with baking and non-uv projected textures/noises).
Maybe follow a few tutorials first. Much success!
thanks for your help. i UV unwarped it again, will this work?
At a glance, yes unwrap looks much more useful 👍️ Just try it again in Painter (reimport mesh via project configuration, bake, iterate). Make sure you have sufficient space between islands (padding).
thanks for helping me out i will export it to Substance Painter, also will this UV work on Substance Painter?
fnally ! it worked, the ID maps work pretty well but I have small issue When I start paiting or texturing there are some artifacts around the edges
No, this won't work for baking. But can be used to apply textures and such in painter. You could paint on all of those stacked uvs, but it'll jump around as Painter doesn't know which UV island to properly stick to.
how about this then?
Try it yourself and find out , but yes those will work for baking. Depends what this ultimately is for, those UVs can certainly be improved to have much more texel density by stacking/overlapping certain repeated elements to save on precious space.

Clean geometry helps with unwrap too! The mesh attached in your original post is pretty wonky in places: Duplicate geometry (top and bttm, stand supports), concave ngons (body), crooked shapes (horizontal handles) and large areas that are not visible (top, bttm, body). This makes unwrapping tedious and likely wastes some uv space - unnecessary for such a simple object.
thank you so much for helping me out, it finally work as it should
