I have been working on my game for a little bit now and i realized i might have a problem.
I usually model my assets in blender and then export it to unreal and this has been working fine. However I only just now found out that the average height of a human in blender units should be 2 meters. Now I wasnt aware of this when I originally made the character since I was still very new and I made it 6 meters in blender units.
And then I made all of my assets according to the player so it would all make sense and didnt feel like the player was too small or too big.
My question is If scale matters for performance, rendering or could it have any impact on the game later on, like lighting issues or more resource consumption?
Or maybe stuff to do with animations and skeletal meshes?
If there are such issues I could still scale everything down as I am still pretty early on and although it would be a tedious task it would still be achievable.
And one more question: if i do have to scale everything down a bit is there some way i can easily do that or would i have to scale every asset on its own and then reassemble the entire level?
Yes it matters, but it’s easy to fix. Go into the mesh file’s settings and find the settings “build scale” and adjust it until it’s proper. This will cause it to treat the file as though it was originally correct in the import.
This response doesnt make sense with the question. I have an entire map with around 900 assets and they all have been made according to the player which is around 3 times the size of what it should be. The image is just proof that it is way bigger.
Right, so then go into the mesh settings and set the build scale to 0.3 and then the engine will treat the asset as if it was authored at the correct scale.
I think your reply is a bit rude as @BananableOffense is just trying to help you. Anyway…
BananableOffense give you the in-engine solution of scaling some imported mesh by changing import settings. Now If you have a lot of assets with the same ‘scale error’ you can multiple select those meshes and then go to option Bulk edit via property matrix
there you can fix the scale for all the selected assets at once.
lets be real… i think the best option is to rescale everything in blender. proper metric scale. and reimport it.
even if you scale everything using the property matrix, your modular assets will scale in place and not relocate relatively. that’s just how transforms work.
it’s a laboreous task but for the greater good of your project’s asset pipeline you should do it properly. don’t do the hackery.
but what im trying to figure out is if its even worth to bother. I will be making the assets myself so is there a point to actually scaling down to what the engine considers the accurate size…
well… scaled up you gain 3x the precision for asset locations, but you loose map size. the default landscape is 8 kilometers squared. scaling up you only have 1/3 available. so you limit your map size to 2.7 kilometers squared. it’s maybe not worth it for your project, but you should consider it.
also… having accurate metric measurements will make it easier to snap using the grid. scaled up you will hit points where the props will overlap, due to precision inaccuracies. technical things. but… if you wanna squeeze the most out of the engine without having glitches you should stick to the default metric.
Well then I dont think I will change it. Its not an open world game and the bounds for the map are already pretty much in place and Im still very far away from the world limit. Even if its a third of the size.
And if it doesnt have any negative impact on the game then I wont change it.
But I will keep it in mind if i ever want to expand or make a whole new level.
