Create Quick Material in foreach

[Spike]

Hi i want to create/assign different (quick) materials in a for each loop - somehow it doesn't work out as expected -> each loop I create an object, in the labs quick material I name the material based on "iteration" of the meta tag

but at the end the shop_materialpath is the same for every element - I guess that each loop the material gets assigned and in the next loop overwritten -> and this way all elements update their material path.

What is the best way to handle this problem - the goal is to create procedural many materials for unreal

ps: I also tried the same thing with copy stamp sop

 

Thanks for help

what you want to do is to create different materials first and then generate a shop_material path attribute inside your loop, that's pointing to them. 

alternatively you can choose a reverse approach where you have a single material and for each piece you generate different parameteres (like texture path) that are then piped into the material. depends what you need to do. 

the setup i see at the picture doesn't make much sense. what you are trying to do is to have multiple names for a single node, which can't be done.

even if it somehow worked, you'd end up with having the same material for all pieces, only with a different name. so at the end of the day it'd be the same like having the same material on all pieces.

cheers, D.

As i mentioned - the only goal is that unreal realizes that every grid created in the foreach loop uses a different material so...

... thats the reason this solution doesnt work too

so the question is what parameters does unreal need to know that an object has a different material

ok this was simple - didnt know that the fbx export or unreal are fine if there is just a different shop path....

@davpe thanks for your help - helped me to ask the right question
