I'm using 1.7 on XP (32) and when I've altered an mxm (seems when a new bsdf layer is added) it will not export correctly. When I try to render the scene, it will not render -- it stops at the mesh in mxcl and will not start the render.

If you can upload the scene somewhere, as simple as possible, or send it to me I can take a look.

Mihai-

Thanks for taking a look -- I've just emailed you files.

I did the same thing as you described in your mail - I added a second bsdf to 'material' and clicked render, and the scene started to render fine.

Do you mean you add a new bsdf, then do a Pack & Go, then try to render that scene? You have to save the scene first I think before doing the Pack & Go.

Mihai-

I think of it as a studio issue because the file seems to work when writing from Rhino (using "Export to MXST"). Once exported from Rhino it opens automatically in Studio from which I then write the Pack&Go (everything looks fine, all the materials are there that should be and I've done a test render).

I open the Pack&Go file on another machine (it happens to be Studio on OSX) and the materials that I have altered (added a bsdf layer while in Rhino) do not appear.

The meshes are there, but there is no material assigned to it, not even a default material. If I try to render the scene, mxcl stops before starting the render -- giving error messages to meshes with unassigned materials.

Another tip-off (from my limited view on the workings of the software) for me is that the Pack&Go file should be the same size or larger than the "Save As" file from Studio -- but it's not. The Pack&Go file is smaller.

Don't know if this explanation helps.

This Pack&Go is the file you sent me? Because it has less materials than the Save As (since Pack&Go doesn't export unused materials), but all the objects in the Pack&Go file have materials applied to them....

[jvanmetre]

Yes, in Studio before I use the Pack&Go, the objects in the scene have materials applied, and the scene renders fine.

I've got to rethink this...my recollection is that I removed all unused materials in the scene before using "save as". That would mean that the Pack&Go should be larger or the same size because of textures?

It's a bit frustrating...I've got another scene I'm working on where all the materials are applied in Studio...I can go down through them and they are all there assigned to objects. When I use the Pack&Go and then render on a different machine -- some of the objects (usually just a few) come up as not having materials and the scene doesn't render.

Mihai-

If I rename the material (which was originally altered in Rhino) while in Studio then do the Pack&Go, the material seems to export fine and comes into a new Studio session fine.

There is something about an altered mxm in Rhino or Studio that causes a need to rename it in Studio before doing a Pack&Go.

I think an mxm altered in Rhino must be saved before "Export to MXST" can happen. Right now Rhino just allows me to do a "Export to MXST" --assuming it's automatically saving any altered mxms before writing.

Okay.

This is just completely frustrating. The renaming technique only worked once and it's back again to not exporting (Pack&Go) changed mxms.

I think Pack&Go is broken. The work around is using "save as".
