Normal maps issue

Hello. I have problems with iray and normal maps. The outlines of the grid and quadrilaterals are visible. So there is no normal smoothing in Daz?
How can I fix this without subdividing and removing normals from the material? Even the blender has a smooth groups that removes it from Cycles

  • This looks like the Shadow Terminator issue, not unique to Daz Studio. I don't have links to hand but it has been discussed in the forum and, in a broader context, elsewhere.

    It's clear. Then there is no point in this program. If I need to transfer the character to another application to render it. Genesis 9 was done, but Shadow Terminator could not be added to the program. Cool. 

  • You don't need to transfer it, I just meant that other appl;ications can have the same issue and so you may find generic advice beyond the daz forums - though it has been discussed, and various suggestions/workarounds offered, here too.

    Вам не нужно переносить его, я просто имел в виду, что другие приложения могут иметь ту же проблему, и поэтому вы можете найти общий совет за пределами форумов DAZ - хотя это обсуждалось и предлагались различные предложения / обходные пути, здесь тоже.

    I've learned everything I can. This problem is for all users who have cards with RTX, and the more powerful the card, the more these problems. This can only be fixed by increasing the grid resolution. Because RTX rendering works fine only on game engines. I took a closer look at the Cycles blender and there it problem too. In short, this problem cannot be solved in any other way, except at the hardware level of the application itself. But from nvidia, of course, no one will buy software for adapting RTX
    I remember exactly that on the 1060, which I had before, this was not the case. But rendering on it can take hours

    This happens when an object receives high contrast light values. As said, it is known as "shadow terminatior issue" or just "shadow terminator" and plaques a lot of render engines including Cycles.

    Just a random google hit (blender shadow terminator issue) hit gives you this:

    A lot of information regarding DS here:

    I think, it got better in the latest versions of Iray, but I have not tested it explicitely.

    Nah. It's all nonsense. Neither method solves the problem. IRAY works well only on meshes with triangulation (which does not work normally on a subdivided model, where triangles turn into squares) and on a subdivided model
