What is bone limit in UE5?

[noceed231]

How many UE5 bones are available on mobile?
After searching, only 75 came out in UE3, so I’m asking here.
Are there still only 75 bone available?

Hi Noceed, Welcome to the Forums,

The bone limit was 75 in UE4 as well.

I found this thread which pointed me to:

inline int32 GetFeatureLevelMaxNumberOfBones(ERHIFeatureLevel::Type FeatureLevel)
{
	switch (FeatureLevel)
	{
	case ERHIFeatureLevel::ES2:
		return 75;
	case ERHIFeatureLevel::ES3_1:
	case ERHIFeatureLevel::SM4:
	case ERHIFeatureLevel::SM5:
		return 256;

So depending on the ‘feature level’ you’re targeting, you might be able to get away with 256 bones. (Or you can change the max + recompile the engine)

Hope that helps, if you actually are able to use 75+ bones on mobile, let us know!
