How to get uv coordinates sets from triangular meshes?

#1

Hi all!

I’d like to retrieve all texture coordinate “channels” from my Mesh objects using MaxPlus but I’m not sure how to do that.

For instance, imagine I’ve got already a mesh:

obj_state = node.EvalWorldState()
obj = obj_state.Getobj()
triobj = obj.AsTriObject()
tri_mesh = triobj.GetMesh()

The GetMeshmethod gives an instance of Mesh, and all the listed methods are here but I don’t see which ones would be the relevants to acomplish the task.

To retrieve the positions and normals I’m using GetVertex and GetRenderedVertexNormal respectively and now I’d also like to know how to retrieve the UV sets.

Anyone? Thanks in advance :slight_smile:

GetCustomMap() -> MappingChannel -> …

@denisT Nice… It seems that a TexMap.GetChannelMap will give you the channel id that’s required by that GetCustomMap method

I guess one possible way to know how many uv coordinates sets are used by a particular mesh you need first to figure out which are the “channels” used by its material… right? Or maybe there is another way to figure out which are the channel maps used by a triangular mesh?
