Multi-SubObject MAT on Loft path not working

[RickHebert]

Hello,

 

My title on this thread is wrong, sorry about that.

 

I am just learning about Multi-SubObject materials, and their application and though I have gone through several resources, including the manual, I have not yet found the solution to this problem I am having.

 

The problem; My "lofted-object" is not updating sub-materials modified on the "get-shape's" sub-objects, and my "lofted-object" is not updating modifications to the "get-shape's" geometry.

 

The "lofted-object" WILL display these properties when the "lofted-object" is created though.

But nothing I do will change the "lofted-object" afterwards.

 

I did this;

I created a path and a shape and lofted them.

I created a multi/SubObject material with 4 different material ID's and used standard materials with different colors, no textures.

I applied this material to the "lofted-object".

 

Next, I applied different material ID's from that material to different segments of the lines of that "get-shape", and I expected the "lofted-object" to display the changes of the subobject material but they are not.

 

Also, the "lofted-object" will not show modifications to the "get-shape's" geometry, like- divide.

 

It's as if the link between the "get-shape" and the final "lofted-object" is broken, but I have done nothing that I am aware of to sever that link.

 

What might I be ovelooking or have not accounted for?

Hello Rick,

Try selecting the segments in the profile that you want for your 1st ID.

Go to suface parameters and check that your id is set to 1. Check also that

this id corresponds with the id set in the material editor.

Do the same process with the next id.

Once this is set up correctly you should be able update automatically through the material editor.

 

If none of this is working it could be that you have lost your your link to the profile.

If this is the case maybe you can revert back to a earlier saved version of the loft

Hello Nigel

What I found was that the profile shape needed to have one vertex welded. I would have not guessed that right away because the shape lofted and it seemed ok.

 

I am not sure but maybe when I created the splines I somehow didn't properly connect the dots.

 

It gave me fits until I found it.

 

It was also giving me a strange rendering anomoly I didn't catch at first. That was the clue that made me look at the geometry again.

 

I have another question if you don't mind;

After I change the mat ID. on a spline on the shape profile, the lofted shape doesn't update automatically.

 

What do I do to make the lofted shape reflect the changes I made to the profile?

 

thank you for the reply.

You might try to drag and drop your material onto the loft, or use the material update button (put material button I think).

This will help the editor register the change.

hope this helps

Ok thanks
