Erm, anyone know how to stop this occurring?
My main aim, for only about 5 years now, is to use displacement to make realistic, modern brick walls. I can close up the gaps by adding a smooth modifier of over 90degrees to the geometry but that makes the corners look wrong and rounded. It also puts weird shading on various parts of the wall. I guess this is due to the over 90 degree smooth modifier but there's no other way to close the cracks.
I tried using the displacemnt shift to close the gap but that causes the mortar to then overlap and look wrong...
Is it actually possible to use displacement here without ripping the geometry open and making these cracks?

I'm getting same/similar results and woudl like to know very much is there any "trick "how to solve that beside adding chanfered edges to corners of house/building.

Only a guess, but would a creating a new UV for the main geometry do the trick?

Displace will do that at UV edges. If you wrap your UVs around, it should stop it from tearing.

Don't think it's the uv mapping. It's a just a box map which works fine for diffuse and bump going round corners. It only goes pear shaped with displacement.

I've tried it on just a box with a new uvw boxmapped onto it and the same tearing of geometry happens.
Same on an extruded line.
Tried edit poly - chamfering edges but it just ends up a mess.

So frustrating that sticking a smooth modifier will close the geometry perfectly. Shame is messes up the shading though.

Hi Karba

Don't know if this helps but check out a similar thing in max when using the displacement approx modifier. In it, turning off split mesh seems to do exactly what we need. Doesn't seem to work when using Octane though. I'm using v 2.15

The important bit is about 6min 50secs in...

Karba? Fooze? Anyone...

Hey Rik,

Didi you ever solve this issue? I am currently experiencing the same thing.




Thanks
