Hi I am getting this annoying artifact apearing on https://www.daz3d.com/dforce-su-latex-outfit-for-genesis-9-81-and-8-female on the latex version of the outfit.

There seem to be squares in the normal map the leather version is not showing this up is there a way of fixing this or can it only be done in post?

    I don't have it.

    There are 2 normal maps. You could you try changing normal map if the boths are for the full outfit, or dialing the normal strength down?

    I can only see one normal map in use in the product,  displace and bump have no assigned maps

    If I turn the Normal map down i loose all the wrinkles and detail though.

    The file list these:

    • /Runtime/Textures/Sue Yee/SU Latex Outfit/SU Latex Outfit Normal.jpg

    • /Runtime/Textures/Sue Yee/SU Latex Outfit/SU Latex Outfit Normal03.jpg

    You could try select all surfaces, on the normal map left click and browse, and select the other normal map. I would assume there is a reason why there is two.

    Could you try blurring it?/inpainting it

    If the  other normal map didn't fix it, I would suggest taking it into an image editor, and paint the trouble area blue (127, 127, 255). Then there won't be any influence from the normal map in that area.

    Hi @fjm1977 Bluring is the same as reducing its effect away go the wrinkles

    Thnaks @Felis I will give that a go but the artifact is everywhere and the lighting shows it up.

    That sounds weird.

    You could consider raising a ticket.

    Looking at it, this is artefacts from the JPG compression on the normal map.

    Unfortunately, JPG is a poor choice for textures, especially normal maps, and I'm really not sure why people keep using it.

    I tried using photoshops neural jpeg artifact filter to remove the noise and lets just say it made a total hash of it, I cant believe Su Yee thought this was a good idea.

    Actualy looking again at the promo images you can see them on the stomach area.

    Heh, I thought that was the result of a botched navel removal job.

    JPG is the standard (at DAZ) for Base Color/Diffuse maps and Roughness/Glossy Maps.  It does keep the size of the files down, since these are the images most used and in some products there are many.  Normal maps, metallicity and bump/displacement should always use png (compressed) or tif (uncompressed) images, for example, to avoid compression and artifacts.  PNGs do not cause the artifacts that jpg does, and although slightly larger in file size than jpg, they are significantly smaller than uncompressed images.  Not everyone is aware of this.  It does increase file size, but is worth the trade-off.  If the user is concerned about file size, they can always compress the files however they like.
