Sided material loss problems

[kingjin]

Material given to the bar after the front side , save the file , and then open the file , single-sided material is lost , what do I do ? Thank you.

Simply create another face or solid in front of it.

Great lighting I must say.

here is the result.

akinlolu olugboji, thank you ,Do NXT does not support single-sided media stored ?

[Roy Hirshkowitz]

I don't know what you mean by single-sided.  Do you mean:

A material assigned to one face of an AutoCAD solid?

[kingjin]

Roy Hirshkowitz, yes.

[Roy Hirshkowitz]

Couldn't find anything wrong.  I did the following in AutoCAD 2013:

1. Opened the drawing.
2. Used the ctrl-click method to select the front face of the counter.
3. Used the AutoCAD Properties DB to assign the tile material to the face.
4. Saved the drawing.
5. Opened it again and verified that the material was still assigned to the front face.

Here's a drawing using the Hybrid engine and the Interior Light preset:

I use AutoCAD2012, you said third step is how to operate , I was assigned directly NXT material functions assigned to the surface .Without using AutoCAD features.

[Roy Hirshkowitz]

It shouldn't matter how you do step 3-- this is an AutoCAD thing-- anything you can do to assign materials to faces of solids is equivalent.  If I'm remembering correctly, AutoCAD did improve this feature during the 2013 time frame.  That may be all we're running into here.

[kingjin]

There are two kinds of situations described below: 

1. If the entity does not confer any material , then gives to the surface material is effective 

2.If the entity had previously given material , and then on top of it to the surface given material , then surface material failure .

This is my result of the operation .

[Roy Hirshkowitz]

Not in my case-- the solid above did have a material-- called q in your model.  It's likely an AutoCAD thing which improved during 2013.

[kingjin]

Roy Hirshkowitz, thank you for your answer , I passed AutoCAD2012 own renderer AutoCAD sided material is no problem , NXT rendering AutoCAD sided material is also no problem, but rendering NXT NXT -sided material does not display , AutoCAD rendering NXT -sided materials do not .

[Roy Hirshkowitz]

I can't help you unless I can reproduce the problem.  You'll need to explain exactly how you make it happen, in a step-by-step fashion.  The term sided-material does not mean anything.
