Collada Import from Spore?

by George Dol · in Collada Test · 08/10/2009 (9:37 pm) · 8 replies

Has anyone tried pulling in a model exported from Spore?
(FYI Sporte patch 5 allows the export of a creature in collada format. it even exports normal, specular and diffuse light maps)

Instructions on how to export a model from spore (and pull it into blender) can be found here http://forum.spore.com/jforum/posts/list/38779.page

The collada file exported from spore is supposed to even contain bones, but I have yet to verify that.

If someone wants a bunch of collada models from spore to test, I've got a bunch...

If you send me some of your spore creations, i'd like to import them into Torque 3D.

Just zip em and send em to me at kenh AT garagegames DOT com

I would also be very interested to have some spore collada models for testing.

Sounds interesting to me as well.

For those following this thread, Spore collada models can be imported into T3D! A small change is needed to prevent a crash due to the models missing the <bind_shape_matrix> element.

In ColladaAppMesh::lookupSkinData in colladaAppMesh.cpp, just edit the bind shape matrix access to look like this:

// Get the bind shape matrix
   MatrixF bindShapeMatrix(true);
   if (skin->getBind_shape_matrix())
      bindShapeMatrix = vecToMatrixF<domMatrix>(skin->getBind_shape_matrix()->getValue());
   bindShapeMatrix.mul(invObjOffset);

The next build of T3D will have this change in place, as well as automatically writing normal and specular maps to materials.cs.

Just a question about exporting a creature from Spore into torque 3D...can we use these models in a commercial product (like as in, use them in a game we make and then sell...coz technically, we have made the model)

Going over the EULA from spore that pops up when you export your first model, it appears the exported model can not be directly used in a commercial application.

Chris:
Regarding the lack of bind_shape_matrix, would you consider that a bug in the spore exporter? If so, If you can point me to the section in the collada spec, or some information on what is expected in <bind_shape_matrix>, I can pop over to the spore forum and post a bug report

Hi George => it's not a problem in the Spore exporter, but an oversight in the T3D collada loader. According to the collada spec, the <bind_shape_matrix> is optional, it's just that I had never encountered a skinned model that didn't specify one before so hadn't added an explicit check for it.
