material changes when reopen a drawing

[Miguel Tano Adanes]

Hi Roy, I have this problem: I set up a carrara marble material (quite a long time to reach the desired effect!) but when I open again the drawing the material has changed and I have to set again all values. I also saved the material to a file, nxt charges it without problems, but if I close and open the drawing all settings are different. The image shows 20 passes renders without path tracer: on the left the material as I want it to be, on the right how it changes when reopening the drawing (also the entire image changes a little bit). Any suggestion please? Thanks

The image is not attached.

Didn't get any images.

Here it is, sorry!!

[Roy Hirshkowitz]

So the .ArMaterial file is correct-- but when you save the material in a drawing it isn't?

[Miguel Tano Adanes]

When I close the drawing and I open it again, some (hope only some!) settings of the material are different respect to those I set up initially, especially the first marble layer.

[Roy Hirshkowitz]

Is the .ArMaterial file correct?  For example, when you edit it using the external Editor.

[Miguel Tano Adanes]

Nop. I opened it in the material editor, changed some values, saved it, closed and reopened: settings changed again!

[Miguel Tano Adanes]

It seems to be the same problem I was experimenting with old AR3 material libraries, actually, when all procedural settings were not the original ones.

[Roy Hirshkowitz]

You're still not quite answering the question.  I can't begin to look at this problem until you do.  When you open the .ArMaterial file that you attached here in the external Editor are the values correct?  I don't care yet what happens when you save it-- just when you initially open it.

[Miguel Tano Adanes]

Nop. Values are not as I previously set them.

 

This is what I want to be.

 

 

 

This is what they persist to be.

[Roy Hirshkowitz]

Ah-- that's what I needed to know.

Roy, I've been playing a bit with it. What I found is that Z values set back to the same value of Y, wether if locker is closed or opened. That happens in all procedural layers (marble as well as granite). If I change Y values it's ok (and Z changes in consequence!), but if I change Z values (locker closed or opened) the editor doesn't memorize them. Try by yourself if it happens to you as well.
