This is crazy.

I’m importing AutoCAD solids and Rhino solids into MAX2012 and as I create materials with noise maps for various looks (my Swiss army knife of quick looks), it renders odd.  Vertical stripes, like the material is sliced up and repeated. (See attached)

Even weirder, the effect is fine for a noise size of 2.0 or above.  When the size is less, then the effect appears.  I need smaller sizes for a variey of things.  It’s killing my productivity.  I’ve wasted most of the day on this.

I’ve NEVER seen this in 20 years.  I go off for the holidays, come home and get back to work.....now this is happening everywhere.  It started when I added AutoCAD solids from an existing DWG project file into an existing MAX scene.  It didn’t do it before the holidays.  Now it’s killing me.  Trying other things....I sent the DWG file into Rhino then wrote a 3DS file and imported that into MAX2012. Same problem.  I created new solids and nurbs in Rhino and brought that 3DS export into MAX2012, same thing.

I just don’t get why this popped up out of the blue.  Really strange.
What the heck is going on?!!

Never seen that; anyway try attaching the object to an editable poly object created in max and check whether the issue is still consistent.
Is it a view-port issue, or is appearing in render as well?

I can’t speak for ACAD solids as I don’t use them.

But for Rhino surfaces or solids, sometimes they simply import incorrectly, even if they “look” right in Max’s viewport. Sometimes normals are messed up and can leave black streaks.

If you have imported your Rhino model as an obj, take the resulting poly or mesh in Max, select the base surface or element within the poly or mesh, and detach that surface to a new object. Then delete your now-empty originally-imported poly. That usually solves the problem.

ACAD objects geometry is typically imported different. Try adding a UNV map and create a new material. Should solve your problem.
