ProBuilderize doesn't retain materials as expected

Hey guys,

I'm currently prototyping a level using some meshes I exported from another project which was originally in OBJ format and was exported with the original materials attached. The geometry is fairly simple, but I have reason to manipulate the meshes fairly frequently in the prototyping and the easiest way to do that is just to ProBuilderize the object and extend the meshes with ProBuilder.

Perhaps a fairly niche use case, I'm not sure, but ProBuilderize (in the latest ProBuilder version in the Package Manager) isn't quite working how I'd hope.

Here's an object I want to ProBuilderize:



And the properties in the Inspector which show the different materials:



Hopefully nothing too unusual here (though I'm new so I don't understand everything).

And this is what it looks like after I ProBuilderize:



Once it is ProBuilderize, the Inspector doesn't change much. Which feels kind of odd because the materials which are no longer applied to the faces, are still present:



It's not insurmountable. I have to reapply the materials to the correct faces, though I'm sure you can appreciate that's fairly tedious.

Does anyone know why this is happening? Is it a bug? Am I doing something wrong?

Any advice is greatly appreciated

Chris

 

I've done a bit of testing. The two most relevant versions to this issue are ProBuilder 3.0.9 where it last worked, and ProBuilder 4.0.2 which is the first version I can access via the Package Manager where it doesn't work.

So the issue could have been introduced in 4.0.0, 4.0.1, or 4.0.2.

If there is a more appropriate place to report a bug, let me know, thanks

 

Thanks Karl.

I've just submitted the bug report now with a sample project and the source model and materials. Very easily reproducible, hopefully it's something that can be fixed and not something wrong with the source model.

 

Already using 4.0.5 and same problem unfortunately.

 

I have the same issue. Probuilderize mesh with multiple materials works correctly only in 3.0.9, further up to version 4.0.5 the problem is reproduced.

 

Hi all.
As quick and dirty hack, you can modify one line in ProBuilder package.
In Submesh.cs change line 200
from:

var index = Array.IndexOf(materials, face.material);

to:

var index = face.submeshIndex;

face.materials is deprecated, looks like it was just accidentally forgotten in Submesh.cs.
Works for me on Probuilder 4.0.5
To make this fix permanent, you can move Probuilder package to Packages folder for some time, and wait for new version to fix it.

 

That absolutely works, thanks!

 

Works great, thanks

 

I exported my probuilder mesh from a previous project as an obj. I haven't been able at all to use Polybrush even with this version.

I'm at the point where I'd rather work on it in Maya instead.

EDIT: After uninstalling the Asset store versions and importing from the package manager, then using either Tools>Polybrush>Bake Vertex Streams or Update_Z_AdditionalVertexStreams, I can now, almost consistently use texture fills.

My only issues now are that I can't view many of the textures from certain angles or distances. Some planes also won't let me fill them for some reason.

 

I can't believe that in 2022, this still works for me. Thanks bro!
