Lower wall materials showing through - finish is stucco

[TomBiggs]

 I'm getting a weird effect where the lower wall layers are showing below what should be a solid material of stucco.  Anybody have any ideas of what can be causing this?

Classic Z fighting. IS the plan far away from 0,0?<br />How thick is the stucco?

[TomBiggs]

0,0 is lower left corner of building.  Stucco material set to 1-1/8".  I checked video settings, acceleration, and left it set to be managed by application.  I have a pretty beefy card.  It's an AMD Radeon HD 7800, with 1 gig memory.

Actually....I checked it.....0,0 is about -28', -40' for some reason.  Is this going to cause the graphic effect?

If you get too far from 0,0 there is more trouble with Z fighting. Not sure how far out it starts.

There is another setting that helps but I cannot remember what it is. Maybe someone else will chime in.

Check the knowledgebase there is an article on "flickering" , for some it helps to set the clipping distance too 300" instead of the  default which I think is 24 or 48"
