Hi!

Currently max bone influences is limited to 2 I'm guessing that's what's causing the issue. Perhaps you can just remove the green triangles underneath the shell?

I like the 3d model btw!

The shell is a seperate mesh object ?
Check the shell mesh`s vertex weights for skinning
and also another tip you might want to remove the
body that the shell conceals if you really dont need it .. I usualy split my meshes like torso head
legs and hair so i could also just hide some meshes
which have clothing very close to the surface of another mesh

RE: fbx animation import: low accuracy
yes there is more than 3 bones. it would be good to fix this restrictions for this good engine. i like rendering. but this issue is so sad

>>The shell is a seperate mesh object ?
yes
>>Check the shell mesh`s vertex weights for skinning
in other engine(Gamestart3d) animation is ok
>>and also another tip
and what about right side picture?

Thank You smile

RE: fbx animation import: low accuracy
I see this . But a simple problem to solve
like i said the same thing esenthel said ..
Remove the body part concealed by the shell
if you dont need it but if you do like plan on
removing the shell during game i recommend
you split the body part the shell conceals so you
can just hide unhide it if you need to ...
Its your choice ..

Hi,

The next engine version will use up to 3 bone influences per vertex (an increase from current 2)

That's a good thing smile

I'm curious. What's wrong with a 4-bone influence (as in Ogre engine, if I'm right), additionnal computations which could be saved ? Is it really perceptible as overload ?

RE: fbx animation import: low accuracy
For most cases 2 influences were enough, while 4 I think is overkill.
Each influence is extra 2 vector*matrix transformations per vertex.

I'm thinking of sticking with 2 influences for mobile devices.

RE: fbx animation import: low accuracy
is it possible to make swither(2 or 3) in engine settings or as flag in api.
thats really good fps on android devices for current settings for my animatins.
as i remember(on other engines) animation can slow down application wery well on mobile devices.

Sorry, that would make almost 2x more shaders (engine.pak being 2x bigger)

RE: fbx animation import: low accuracy
Looks like you have vertices that have lost their weighting (are unattached to bones)
