  • Custom mesh with multiple materials


    I have a custom mesh with 2 materials on it.
    I export it to speedtree in obj file but I can't find how dissociate the two parts of my custom mesh.
    I would like apply one material for each part and, the most important, I would like to have these parts on return to my software.

    Actually I have just one merge mesh with one material.

    Do you have an idea how can I achieve this ? Thanks.

    Unfortunately, SpeedTree does not support multi-material meshes. You would need to combine the textures in one image (like an atlas map) and re-UV map it. From there, just import the mesh and apply the Material on it that has the combined texture.

    Hope this helps.

      Thank you for reply.

      I'll take note of combine textures technique. Unfortunaly, In my case I need 2 real differents materials and not one big with a blending of two heterogeneous shaders.
      But I find a workaround : In my 3D software I move uv of the second part of mesh on a the side (like 10 unit on u). And when I get back my mesh to my 3d software, I easily select uv of the second part of object and detach or create cluster from this.
