Hi, I'm doing a track for nk-pro, but first I want to do some test.

I work with Bob Track Builder, then export to rFactor format, and then import in 3D Studio Maxi with the script GMT2 Importer. All perfect here.

The problems become with the multimaterials. So netkar-pro editor don't admit multimaterials, I have a script (Detach by ID) to convert this multimaterials in single materials, but I have problems.

That is the message of the error.



Also if I check "Use Prefix" on the script and type a name, when I click on DETACH, give the same error but stop the code in other line.

I think the problem is with the gMaterials that are using shaders from rFactor, but I'm not sure, I don't know so much about 3d Studio

I’ve also had problems with the script, my MAXScript Rollout Handler Exception was --Unable to covert: ReferenceTarget:ReferenceTarget to type: Material, and I also noticed that playing with the options just changes where the error occurs. Sorry I’m no help (but least you’re not alone)

Do you know if it is possible to export from BTB to directx and then import to 3D Max?

So if the problem is the gMotorMaterial, exporting in directx will not use that, and will not have the problem

Attention you must not detach all objects.
Some do not need to be detached, some willing to be seconded to other objects and some accept dettachement of material.
it is not easy and need lot of experiment.

Can you to explain better?

The track in what I'm doing test it is very simple and only has 2 materials, grass and road, 1 object is road, and about 15-16 meshes of terrain.

The track in what I'm working has a lot of more objects and materials... what rules we have to follow?

Why is useless to detach the terrain? For the terrain I had used a lot of textures
