    Revit Model Linked into 3DS Max - custom textures do not show

    I'm linking a Revit 2013 model to 3ds max via FBX and the file link manager.
    I have done a number of tests to diagnose where the problem lies...

    here's what happens:

    1.Export to FBX
    2.link FBX into max.
    3.Materials are all fine.
    4.close max. (as in end of the day)
    5.reopen max the next day, and materials that I have made are no longer there. after choosing the material from eye dropping one of the surfaces (which I can see is assigned but not showing) looking at it's properties, under the image location I get a msg saying "Invalid Asset Instance!".

    I've figured it has something to do with the material that i assign in revit as with a standard out of the box material of revit's works fine. the texture is a .png file like all the rest in the OOTB materials. note also that i did not use the paint tool in revit. but through testing figured this was not the problem.
    I'm guessing it has something to do with the appearance in revit and what appearance I have duplicated and ran with. I'm still getting my head around the materials in 2013 like many others it seems.

    I have googled this but couldn't see anyone else with a similar issue.

    Thanks for your time

    Hey, if you're working with Max 2013 & Revit 2013, you can just Link your Revit model into Max directly. No need to export an FBX from Revit, Max will handle it for you. We've been using it all year and had (almost) zero issues with it.

    Maybe try that first and see if it solves the issue.

    Only other thing I can think of (that's not just a bug) is that you're somehow reloading the FBX into Max when you start the file back up the next day, and you don't have the 'retain 3DS Max Material Assignments' checkbox checked. Either that or a file path issue in Max.

    Sorry I can't be more of a help, we've been using Max with Octane Render, so I'm swapping out all the materials anyways and not using the ones from Revit.

      Linking .rvt is the same as linking .fbx. It just creates FBX on fly, even export time is the same.

        I prefer fbx just because usualy my revit file allways change it`s file name incremantally for new updates (not worksharing here). So fbx export has a constant name, a condition you need for reload function in 3dMax in order to preserve max materials. I know i can save a duplicate of revit file with the same constant name ...

          I know, I know, I was just thinking it might work better in this case as it's more automated. I've not had great luck with FBX files from Revit, for they are IMHO kinda broken. I've had better luck with the new Max linking, even though it's doing the exact same thing behind the scenes. No idea why, 'cause I don't have the time to find out. But I've not had major issues with re-loading changes into Max & wiping out my Max material assignments & edits, where before with Max 2012's FBX linking we did.

          So maybe it's just that Max 2013 got better at it, but since we've switched to using Max's built-in Revit link we've had better luck overall.

          Gaby, all our projects are Worksharing out of the gate, and all of our backups are versioned up the waazoo such that I can pull anything at any time. Worksharing is awesome and getting a good versioning backup system in place these days is really cheap and easy. I highly recommend both!

            My "issue" with the Revit Link method (which is no doubt symptomatic of my lack of understanding of Max) is that it brings the entire project across - when (often) I don't want to do that so I like to configure what I'm sending out first in my export view (in Revit) for the .fbx export first. I'm sure there's away to "hide" objects in Max - but like I said, my understanding of the program is v.limited.

              Jeffrey - I have tried all your sugguestions but had no luck. I got all axcited about linking RVT straight into max when I first heard about it. But with the size of the models we're working with, I've never managed to pull it off. A small project yes. And yes I have tried using the section box and hide all that is unnecessary, but then you end up with many max files... and if you want a fly through that's out also.

              I'll have to do some more tests on this one to nail down the problem I think.

                You can do this with the Linking; when you link the model in Max it asks you what View you want to pull from, and it only takes the stuff that's in that view.
                So I setup a non-camera 3D view in Revit called 'Max Export View' or something akin to it, hide / 3D crop stuff there, and then pick that when I do the link into Max.

                411toaster: The models I've been working with are smallish, yes, but with lots of detailed unique families in them. I do remember a long time ago working with some skyscraper models in Max that came from Revit, and we had big issues with the number of objects in Max & face count. Max can choke on both, where Revit doesn't care so much. Are you selecting 'Group As Material' or something, or making everything independent in Max? Using the Pro-Optimizer Modifier?

                Sorry I'm not much of a Max expert! I hate the software honestly. It's just a good bridge to Octane Render for us, so I grin and bear it. I'd much rather use Blender! ;-)

                  Yes I am using the group by material and am using pro-optimise on what ever is necessary.

                  I guess we can just do all our texturing etc in max... I guess the work flow I really wanted was to do as much as possible in revit simply using max to render images faster, and maybe add a few better textures here and there where it's required. ...as an example I've made a Visualisation Workset in revit and placed shopfront images on a thin wall behind the shopfront glass. All is ok, until the file is closed and reopened again.. now I'm thinking I should have done this in Max.

                  Working so much in revit I find modelling MUCH faster when compared to Max. But I guess someone who is a very good Max user would be just as fast.

                    If anyone is interested try what i have done and see if you get the same result:

                    1. make a wall in revit and make a new material for this wall putting it under the structure for the wall type.. I've used a shop front jpg image... duplicate the materials appearance renaming it in the favourites.. all showing good in revit.

                    2. export this to FBX and link this FBX into max ... or just link the RVT striaght in with the file link manager using group by material in max.

                    3.all is looking good in max and matching what is shown in revit realistic mode.

                    4. save this file and close it.

                    5. reopen the file and there you go. diffuse image texture gone walk abouts.

                    Is no one else having this happen? just test a quick wall and see. it'd help me diagnose where the problem lies - cheers
