I have an fbx model (which unfortunately I cannot share) that increases in size whenever I join all the meshes together. The increase in size is most likely due to the increase in vertices, but I don’t understand why the number of vertices increases when all I’m doing is selecting two objects and pressing Ctrl + J.
I checked for modifiers using a script, but none exist on any of the objects.
I’ve heard that it might be due to objects sharing data, thus no longer sharing it when combined, and using up more space. If anyone can confirm that to me, it would be great.
If you have any other idea as to why this is happening, I think it would be good to discuss it here, because I couldn’t find any other post that gave a precise answer.
…well if you have a mesh and joins another… then the number of vertices are the one from the second added to the first…
…or you have to elaborate this… how much does the one have and how much the other and how much does the joint mesh have ?? (hard to tell with this little data, images or anything)
Also @LordoftheFleas : five cubes with eight vertices… joint together makes 5 * 8 = 40 vertices… ( or i didn’t get it…)
He’s probably talking about instances. Blender doesn’t add all the instanced object’s polygons, only the first, and by joining them, the instance lose it’s shared data and it’s polygons adds to the overall count.
Ahhh … yes now i see… @LordoftheFleas you are right… i overseen this… and was just “investigating” … when @Jaxx posted the answer…
( There was also something about any option/addon displaying the real number… so also counting also the instances… and i answered about it some time ago… let me see…)
Edit:
Naahh didn’t found it… but this may be offtopic anyway…
So for example if the original is a car as FBX… then the tires could instances of one tire and so when joint… the number increases…
…
… yes now i see…
