I have three mesh parts, that make up a tree.
However, I wanted to increase the size of all parts at the same time, so I exported it to blender to ‘union’ it into a single mesh part…
How can I fix this?
since it’s a mesh now, under properties there’s TextureID where you can add a desired texture/color using an image
Is it possible to split the texture id before I re-import it? Otherwise, how would I get the exact texture ID?
you would have to edit the UV map in blender. a solution if you don’t want to do this is to export the branches and the leaves separately then just color them in studio like you normally would
or, you can check to see if you already have a .png file of the texture from when you exported the tree from studio to blender
you would have to edit the UV map in blender.
Could you please elaborate on this?
if you group the model on the first picture in studio, you should be able to scale the whole tree, no need to use blender
also you cant add different colours to 1 mesh without making a texture. stick to having seperate meshes to colour them
You could do it like @TM951atSumex suggested it, but sometimes this doesn’t work due to different normals (means that the parts/meshes don’t have the same axis to scale along, which messes the parts up). The best way in this case would be a plugin called “Model Resize” ( Model Resize Plugin Link ). This plugin scales all selected meshes/models along one axis, so that the meshes are scaled properly. I personally use this plugin all the time 
Hope I could help you!
I’m trying to make a script that grows the tree, so that in game, when you plant it, it slowly grows in size. I don’t think I can do this in game…

When exporting from blender, enable this on the export tab and disable all of the other options.
This will group things based on material/color and import each differing material group as its own mesh.
Making textures and messing with UV maps for this is so much of a hassle for such a simple tree. Don’t do that.
Whenever you import the obj file into Roblox, it may error the first time(bc of some weird bug) but when they both show up in your asset manager, select both of them, right click, import with position(something along those lines) and then you’ll have 2 mesh parts. Apply whatever colors/textures you want manually in Roblox.
If the colors don’t show up on the mesh part, delete the Texture from the TextureID of the mesh part.
