3DS Max Material Import Question

Unity Engine
1

Hi, I’m new to Unity but am working as the 3d modeller for a project, but I’m having some problems importing my models.

So I have a question for those more experienced than I: If I create a material in 3DS Max with a diffuse map, bump map, specular map, etc. and then UVW map that material onto a model, export it as an FBX, and then import it to Unity, will all of those material attributes import as well?

For example, I’ve exported a model and imported it into Unity several times, but every time I seem to get different texture results on the imported asset. Sometimes it’ll have no textures, sometimes the texture will show up, but the bump map will not, and I can’t get the specular map to show up at all. The maps I’ve used are all in my project folder however, so I’m confused.

Anyway, this is getting rather long, so I apologize, however any help/tips would be greatly appreciated. Thanks in advance.

You should only assign the diffuse map in your 3D program.

The rest of the assignments are done in Unity…

There’s a Howto for how to get a normal greyscale bumpmap converted into a normalmap here:

The specular amount has to be stored in the alpha channel of your diffuse channel…[/b]

Thanks for the response. But if I Bump Map it in Unity, will the bump map snap to the existing set of UV’s for the object, or will I have to UV map the Bump Map as well?
