how to match the distribution of objects to the unwrap using map distribution

[Lilith5th]

hi,
I have a texture of tiles, and I would like to have grass in the grouts. the simplest way would be to use the distribution map, and apply the bump map to the slot.
Unfortunately, the grass and the texture do not align. Is there a way to achieve this?
especially if we are using unwrapUVW

Hi,

Please make sure to double-check that you're using the Surface > UV mode and that the corresponding Map channel is assigned within the Distribution settings. If that's the case, it would be really helpful to understand what's happening exactly in your scene just from the provided description. If possible, please feel free to send us your scene (ideally simplified and containing just this problematic object(s)). Thank you in advance.

Best regards,

thanks. I will upload as soon as I get a chance.
but in the meantime... what do I do with the "density" Settings?
If I apply a distribution map in the map slot. the distribution map pixels/units is active. and changing it changes the scale of the distribution.

There are several ways to achieve this. The recommended approach is to use the bundled Density by Map (UV) Effect for this purpose. Additionally, you might find the Density by Texture and Falloff Density from Bitmap posts helpful. As demonstrated in these posts, you can blend multiple maps using a Composite Map (or Mix Map) applied as the Distribution Map. I hope this helps.

Best regards,
