Diffeo Texture tiling?

Hi,
I've noticed that texture tiling doesn't seem to carry over from DAZ using Diffeo.
I can't find tiling parameters in either Cycles BSDF or Extended Principled imported materials, and the renders look accordingly with Blender not using the same texture tiling as DS does.

Is tiling data from DS not being imported into Blender?

Thanks!

    Tiling is supported for the uber shader and the image editor, just tested with a simple cube and it works fine. You may want to give exact steps to reproduce the issue.

    Hi Padone,
    Thanks for looking into this!

    I'm using the Cafe Luca asset for this.
    I'm adding the DS export screen as well as the Blender import and the resulting shader screens. And two screens showing the renders from DS & Blender, where you can see the difference in floor tiling.

    Is there a way to export just that shader from Blender to post it here?
    I've fixed the issue by adding a Mapping node between the Texture Coordinate and the DIMG Woodflooring nodes and scaling it by 0.5% btw.

    The uv mapping is inside the DIMG group, but there's a bug because the conversion doesn't handle properly non-integer values, in this case 0.5 for tiling. I'll prepare a test scene and report to Thomas, thank you for pointing this out.

    update. Now reported to Thomas.

    update. Fixed in the last commit.

    Good deal, thanks Padone!

    To add tiling to an image texture in blender you can add a mapping node in front of the image node in the shader editor, then adjust the scale settings. If you have the node wrangler addon enabled you can just select the node for your image then press control T. The mapping node will be added automatically.

    I have also noticed many textures do not have proper tiling when imported with diffeomorphic.
