I have a pretty plain looking cornfield here, and each “corn thing” has 3 parts in it

Basically, I want to combine all of these into one and keep the colour.
Problem, how do I do this?
I’ve tried importing to blender then putting it back into roblox but it always turns a grey colour.
So, how can I do this while having no skill in blender?
I just want to decrease the descendant count in my game because that number is just over 200k, if I remove the cornfield it falls all the way to 83710.

You could try using unions, but i dont know if its the best option.
to make a union, open the top bar, > model > union
and it will make one with your selected parts.
(With this many parts, studio will probably crash though…)
Edit: if these are meshes it wont work i forgot

The problem with that is that sometimes it will make it one colour + materials seem to break

yeah, cant do that because meshhttps://devforum.roblox.com/t/how-can-i-turn-a-model-into-one-part/3517633

dont know why i pasted a link in that last post, i dont remember pressing ctrl + v
I get what you’re trying to do here, you shouldnt really worry about making them a whole, if what you’re trying to do here is optimizing the game, you shouldn’t really worry about uniting the model since, at the end of the day, they’re just parts.
What you could do is unite the parts that have the same color, that way, you can both: Keep the color, and set the material!
What you could also do is: If some plants dont really have a function you could do what i said (uniting the parts that are the same color) but for all plants (unite all plants to one union and all corns to another.)
Example:

Well, it might be hard to do that, but if you need to decrease the amount of models, you could try to make pathways, or small openings in the cornfield which means you can decrease the amount, but the only way i know you can turn it into a single part is just unions.

if you are cool with lowering the detail i can try to turn it into a mesh

Ok @67834_ofalltime, i worked a bit of my magic and reduced part count to about 240 (yes two hundred and 40) give or take, i had to lower the detail a bit but its not too bad, i left the center alone as you seem to want to have that guy there but that does mean there might be a mismatch in the quality.
CornFieldOptimizedFinal.rbxm (182.2 KB) To import go to models tab then click the model button and select this file.
Let me know how that goes.

You can do that by exporting the model as an obj by right-clicking the model and pressing the Export
option. Then, using a mesh part, reimport the model and it will be as a singular part.

Nah you are unable to do that even with a small chunk,

wow, thats a big difference from 200k, ill try this out now!

Yeah the total parts in your game should be around 80k, 240 parts for the corn field now
Well, why are you doing it for a small chunk? Also, why is the model so detailed if it has around 86,784 triangles? It seems very unoptimized and can come to stab you in the back in the future if you don’t do something about it now.
Also, you aren’t the OP?

The model is the one OP provided in a previous post that he decided to move here as it was 2 issues in one post, yes the mesh is unoptimized, turning it into an obj wouldnt help much in that since its made of a lot more meshes, the reason why i was doing it in a small chunk is if i went any bigger it would crash studio as it would be trying to turn however many instances op had in his corn field into a 3d model including all the meshes that are in each part of it adding even more stress to the game
(that is just the small chunk of the original model that was exported)

How will the player interact with this field, if at all?
I haven’t used studio for a long while so I haven’t been able to test these
