Displacement at Corners

OK, so I'm working on some displacement brick textures. I've figured out that I need to subdivide my flat faces into a bunch of small squares for the displacement map to work properly. However, I'm having an issue now where the corners of the building are pulling apart from each other. What's the fix for this?

Set polygon smoothing angle >=90 and Recalc. Turn on smoothing in displacement options. I hope that helps.

cool, I'll give that a shot. Another displacement question. I've tried doing some displacement brick w/ horrible results. After doing some research I think I've found that you need to subdivide the surface into small squares. Is this correct? I don't suppose there's a way around this or anything as it takes awhile to subdivide a big wall w/ openings in it.

It's just better if the mesh is subdivided a bit instead of being one big polygon. If the mesh is subdivided a bit you can use a lower precision value for displacement and have faster render times.
smoothing angle?

Where do I set the Smoothing Angle?

Smoothing angle applies to other applications - it is not available in SketchUp. The solution for SU (as Mihai suggested) is to subdivide the original polygons as SU tends to create big polygons which can cause problems for displacement.

so the angle i can set in skp is not the same like smoothing angle? and is not used by mxw?

I am not sure what you are referring to in this case - I am not aware of smoothing angle setting in SU. What I am missing?

Pavol the smoothing angle in SU can be set via the Soften Edges dialogue panel.
Window > Soften Edges
As suggested abouve would this effect the edges of displaced faces?

Ooops - I wasn't aware of that. Man learns every day
Yes - it should have the desired effect as explained above.

I was always asking myself why we had to "recalc" and why Studio couldn't grab the smoothness from SU...
