Weird displacement mapping

[Pixelab]

I've been trying to perforate holes in metal with VRaydisplacementMod but a strange seam happens. If I put the same map in opacity and add a shell, everything renders as it should.

opacity (map correspond to the UW)



displacement (the weird seam appears every 12 tiling of the map, resolution of the displacement is the same as the texture size)




Any clue where I should look ?

I'm not sure, looks very odd. Can you post that part of the scene?

Ok, next time I'll RTFM first

The 2d mapping (landscape) method will ignore the Tiling parameters specified in the textures themselves; as a side effect this means that it will not work with the Real-world map size options in the Bitmap and other textures. Instead, you must modify the UVW coordinates of the object, or use the 3d mapping method.

Making a test right now with the tiling transferred into a UVW Xform

Ok, that was it. Problem solved !

Thanks vlado for the quick heads up

Oh ok. Glad to know that it worked

Holy shit that just solved a lot of headaches for me, too.
RTFM or not - is there no way this issue can be avoided? As in making it work with texture tiling?
