Export C4D sculpt to Substance Painter

Recommended Posts

Seeing Substance Painter bumping in a lot recently, I decided to try it but I am failing at importing correctly my meshes.

 

I modeled and sculpted a frog in C4D and the best I could find for my workflow was this was this tutorial based on a ZBrush + 3DSMax import.

 

Following it, I saved my sculpted frog and each eye into three .obj.

I then saved the base frog + eyes into a .fbx with triangulate and normals options checked, with a material for the eyes and another for the frog.

I had troubles with normals even if they seemed right in C4D but I think I managed to get them right in my last attempt (but the low poly mesh looks weird and all black in C4D).

 

I tried twice to bake meshes but each time it seems to bug at 42% with the spinning wheel.

 

I attached a screenshot where it bugs.

 

Thanks for the help :)

 

PS : Here is a lousy gif of my sculpted frog

I'm trying to make sense of what you say is going on.  Seems you say there are several problems.

1) won't bake

2) mats show black on c4d

Is this right?

 

I don't know how you are even importing it to painter if you can't bake it.

  • Thanks for the help Fastbee. I must say I'm a bit lost.

     

    I don't know what you mean by "won't bake" but yes, Substance is not responding after a few minutes when I launch the baking process.

     

    However, following the zbrush/max tutorial, I did a first try with only the normal baking and it was looking good (the normals look right on the screenshot, right ?).

     

    Also, I had no problem baking the C4D sculpt into a lower res mesh. I have no idea why the preview is black but when I render it looks like the original sculpted frog.

    I'm not sure what your problem is still.

    Is your problem only with Substance baking?

     

    C4D viewport showing black due to settings turned on in the viewport > Options.  If it's rendering right I wouldn't worry about it.

  • Well I don't know how I could be clearer but here's another try lol :

     

    I'd like to paint on my sculpted mesh inside Substance Painter. I managed to import the base meshes but the program freezes when I bake the textures.

     

    I guess I could share the files via pm I made to see if the problem is coming from them or if it's the software ?

    If you send me an .fbx file I'll be happy to bring it into my version of SP to see if I get the same results.

  • Thanks! I sent you a PM with a WeTransfer link if you want to have a look.

    No worries, happy to help.

     

    Your files opened without issue in C4D and SP. A quick bake took about 15 seconds. I sent you a link to the results. 

     

    Are you having baking issues with other files too or just with the frog?

  • I have baking issues with the frog only, I didn't try anything else.

     

    So you have a smooth frog but it should have some sculpting (you can see it in a 360° video in the PS section of my original post).

     

    Replying from your last PM here :

     

    Should the .fbx file have a displacement map of the hi-res sculpt ?

     

    From what I understood from the tutorial, Substance Painter's baking process would create a new displacement map projecting the hi-res .obj's to the low-res .fbx. Is that right ?

     

    Thanks again for your time and effort.

    Typically I would create a high-poly and low-poly version of the same file and reference them in SP. 

     

    This worked for me;

    Open Frog_HP.obj  in C4D

    Delete align normals tag and material tag

    Create new material and place on frog

    Export as .fbx and open in SP

    You should now have the frog with displacement...at least it works for me.

    Okay, thanks for the idea, but am I not supposed to work on a low poly version of the frog ? 

     

    Especially since I’d like to animate it once the painting is finished.

    In theory, yes, this should work. But when I use your low-res fbx with the high-res obj I'm getting the same results as you...my computer locks up and never finishes the bake...very strange indeed. I suggest you try creating a high-res fbx to bring into SP for your displacement instead of an obj and let me know if that works.
