Hi man,
Looks like a awesome tool was just playing around with it somewhat to look at its potential,
some things seem vague in the instructions and its causing errors when running the files,


4. Edit Batchconvert(Run as admin).bat with the windows text editor or Notepad++ and replace all 3 [PATH TO SYMPLIGON INSTALL FOLDER] parts with the path to the folder you installed Simplygon to. The entire path needs to direct to the SimplygonBatch.exe. Double check to make sure it's 100% right.

what does this mean highlighted in RED above ? :)
replace all 3 what there is not 3 paths there.

I'm also just testing it - from what I gather if you installed simplygon to the default directory, you shouldn't have to change anything there at all.

Yeah I imagined that, I checked and checked my paths it was the exact same paths,
but still its coming up with errors for some reason when I run the batch files,
its extracting the fbx and textures but not running anything :)

Not quite sure what else needs editing,
but like I stated above in my 1st post, seems vague the instructions to what exactly needs altering if anything :)

Maybe once some one has figured how this works they could make a video tutorial.
Looks awesome that would be useful indeed,
I followed what I understand in the instructions best I could,
even using the dragndrop gen, its removing all the files then giving errors it cant find them,
same tool deleting them lol :)

Little write up after testing and comparing this to conventionally made LODs, and what I predicted earlier sums it up pretty well -
Better than nothing is about as good as I'm expecting tbh
I commend the effort gone into creating this, but as expected the results are really not comparable to handmade LODs, and I think the definitely worth the little effort needed to create LODs manually that are better than this.

Here is a quick comparison of my manually generated LODs, vs what this auto generated ones can do (bear in mind I tweaked the CMD file to try and match tri counts between my LODs and the auto LODs, out of the box they are much more tri-heavy!)

LOD A for reference, 239k tris + 139 Objects


LOD B, 30k tris + 78 Objects


LOD C, 8.6k tris + 35 Objects


LOD D, 2.4k tris + 2 Objects



And the auto generated LODs

LOD B, 34.5k tris + 117 Objects


LOD C, 8.3k tris + 87 Objects


LOD D, 5.6k tris + 74 Objects


Sooo yeah. Better than absolutely nothing imo.

and yeah, some models it ****s up, if anyone can provide a better simplygon ".spl" file, this would be great

I dont think there is a dream LOD tool, I always dream about 1,
but no matter where you look they end up similar results to this,
nothing beats hand methods in my book, well currently anyways :)

People always say but curiosity killed the cat, but in this case it killed the LOD :roflmao::p

idk what you all got, at 10% LOD D looks like this, and this is far bigger than what LOD D is supposed to be sized at ~220m:

your manual one:

which one is better?

relatitvity hitting hard ;)
Manual is always better is controlled more, but keep at it and see where it goes,
it shouldnt be optimizing and crushing the boarders of the mesh,
something inside the script is optimizing the mesh wrong,

proOptimizer mod as multiple options, if you choose for example protect boarders it will do so and protect UV also and textures so keeping the same UV space as before,
issues with these things it requires smoothing groups to work,
so removing smoothing and making hard edges, then using that modifier will give maximum results,

for your tool to be optimizing for example doors and leaving black spaces,
its not protecting boarders of the actual geometry,

but even fixing these things, making the LOD and gaining perfect smoothing will be a hard task :)
