Hi guys,

I've created a model (units: meters), baked a texture in it, and it looks correct in 3ds Max. But I can't get a reference to the accompanying texture to be included in a VRML97 export from 3ds Max. A texture reference is missing in the output file.

I've tried adding the texture reference manually to the VRML97 file with a text editor, but then Meshlab gave me errors about missing or too much parentheses, which I couldn't get fixed.

A Zip with the 3ds Max 2012 file and texture can be downloaded from here. Any help would be appreciated.

Many thanks in advance.

Did you try opening the VRML file in MeshLab before editing the file?

Hey Metin,

when you say 'baked in a texture', do you mean you UV-mapped it? Or did you do something else.

I'm not sure how 3DS Max works, but we require UV mapped textures.

Hi Bart,

Did something change?
http://www.shapeways.com/tutorials/exporting_to_vrml_and_x3d _for_color_printing says per face colouring can be uploaded which I experimented with last week - http://www.shapeways.com/model/335991/5e65eaedfe3a0d7faf588c 0043ad250d/colour_police_phone_box_vertex_face_colour.html?g id=ug

Cheers,
Paul

For sure, you can use vertex/face coloring as well. But as sevensheaven was referring to a texture map reference I figured the problem was related to texturemapping Wink

I figured the same, but as 'baked in' is mentioned, I'm thinking that the sevensheaven's colouring is per face.

@sevensheaven - more info is needed please Smile

Many thanks for your replies!

I tried importing the Max-exported VRML97 file in Meshlab first, but it indicates no presence of a texture. When I export it from Meshlab, there's no texture entry in the resulting WRL file, because the texture reference is already missing in the 3ds Max WRL export.

In 3ds Max itself (Standard material with diffuse map) the texture is showing correctly on the model. I have followed the instructions in this page, but used the mesh's own UV coordinates for baking the texture in stead of an unwrap method, otherwise the texture became mangled on the model.

But somehow the texture reference isn't saved along in the 3ds Max VRML97 export. The Max-exported VRML97 file + texture can be downloaded here, and here's the Max file + texture.

Hi Martin,

Have you checked the export settings of the file in 3ds max?
Maybe one of the check boxes is marked as yes but should be no?

I'd be happy to take a look, can you save a legacy max (2010) file ?

Thanks again for your feedback guys, much appreciated.

Virtox, it'd be great if you could take a look. Here's a Max 2010 version of the file, including the texture.

Many thanks in advance. You can also reach me at metin [at] sevensheaven [dot] nl

The material currently assigned to the object is a "shell" material, which is not compatible with the wrl exporter and is thus ignored.

If I assign the medit material, or one of the submaterials of the shell, the texture gets exported mostly correct.
Only the base is somehow mapped wrong, which I can't explain (yet)

Hint: the file will be twice as large if exported ok, because it will contain texture coordinates Smile

I am not sure how to fix the base, probably best to collapse the whole object and reapply mapping for the base only.

Thanks a lot Virtox!

You're right, when I reassign the Material Editor's material a bitmap path appears in the VRML97 export. Weird, as the same material should have already been assigned to the mesh.

Maybe the baking process caused a different material to become active on the mesh. I hadn't used baking before.

Going to reupload the mesh and texture now, hope it works, and thanks again!

Your welcome, btw you can use meshlab (freeware->google) to check how things look quickly Smile
