Importing a model from Mudbox with multiple UV tiles

[Aupuma]

Hi, I'm making a college assignment where I have to make a high-poly model in Mudbox and then export a low-poly version with its normal maps to 3DS Max.

I don't know how to apply the textures properly, because I have 5 UV tiles in Mudbox, so I don't know how to apply multiple tiles to the diffuse color and bump of the material so they get aligned with the model. 

I have thought a different solution where I change the number of tiles in Mudbox to 1 and then export them but when I try to do it, the texture goes crazy and all the painting I have made in the model isn't in the correct place anymore.

Welcome to the forums @Aupuma!

Try this: Make each tile its own material.  Then in a new material create a multi-sub object material and place all the materials into this one.  They should retain their alignment, etc.  Apply this multi to your low poly model.

Hope this helps,

Kenny

It didn't work unfortunately, I have done what you've said and nothing it
doesn't show up as it should, I'll send you some images.

hmm...

It is probably not this; but let's rule it out:  Double check your units and make sure your import is the same scale as in Mudbox.  If you brought in a unitless part into a unitless Max, it shouldn't be an issue.  But if you have Max units set to something else, you may have a scaling issue.  Do a quick measurement check to make sure your models are the same size,

You can also do similar with your materials; jump the tiling up to 25 and down to .25 to see if you start to see something.  Again; probably not your issue, but let's make sure.

If you apply each material on its own, do they show up fine?

Shooting from the hip here; send those images when you can...

Hello @Aupuma and welcome to the community,

To do this you'll want to use the Multi-Tile Map.  Make sure to set the right tile format!  Please let me know if you have any questions.  I have seen some cases where the viewport display is incorrect with the multi-tile map but the render looks correct, so keep that in your mind.  Happy to help if you have questions, or I can also create a private folder to investigate closer if you'd like.

Sorry for my late response, but I tried to do what you said and I have the same results, if you could create that private folder and investigate the files it would be of great help, thanks

No problem at all @Aupuma!  I am happy to do that for you.

Hello @Aupuma,

I owe you an apology, I didn't get the email notification that you had replied here and I am late in getting you an answer.  I am very sorry about that.  I have checked out the scene and I wanted to update you on how to resolve this.  First, the problem is that tiled textures aren't displaying correctly unless the "Show Shaded map in Viewport" button is turned on in the multi-tile map slot.  You'll need to do this for each material in the multi-sub.  Keep in mind, it must be in the multi-tile map slot.  I have a screenshot below on how to enable it.  I noticed when I did a render that everything was looking correct regardless, so it's just a viewport display issue.  All you need to do is hit that  button.

Can you please try that for me?  

Best Regards,
