How to apply Multiple textures to FBX or OBJ Mesh ?

#1

Hello All,

May be this sounds like a newbie question but I really have no idea how to apply multiple textures to a single mesh in Fusion 9.

Like I have downloaded a building asset in FBX and OBJ format. I get a mesh with multiple shapes and all merged together form that building.

Now practically its very time taking to assign material to each object and adjust them using UV.

I dont know if we a simple and easy method to assign materials, I see a ".mtl" file too in that folder.

The simplest way I use to follow is, request the 3D Department guys to convert this into a UV texture and combine the whole mesh into a single Alembic mesh and then I would use that in Fusion.

But curious if we can do the same with multiple objects in FBX and Multiple materials/textures.

Can anyone help me out in this.

Thank You

case 1 : as u say:

case 2: u have all single shapes(Objects), u can connect each with a Shader. Or give them different MaterialIds and the u can use "replaceMaterial" after the merge, und "limit by MaterialID"

Thank you for the reply @ISOTRON. Will try that... But what is this .mtl? Is it of any use for us?

The .mtl is a text-file that normally accompanies .obj files.
In the .mtl there are the path(s) to the texture(s) as well as the properties for each material on the mesh.
Fusion reads the mtl when importing the .obj.
