Set Shape Key Performance Issue

Hi,

When setting multiple shape keys at the same time to achieve animation using the function:

m_geometry.set_shape_key_value

There seems to be a large FPS performance drop between versions 16.02 and 16.06 that is still present in 16.10.
16.02 could handle up to six times as many calls to

m_geometry.set_shape_key_value

for this particular mesh.
It looks like the bottleneck is the CPU and functions like

apply_shape_key_nor

,

apply_shape_key_pos

, and

apply_shape_key_tan

.

Is there anyway to improve performance? For example is there some functionality that is being called many times (for each call of

set_shape_key_value

) that could only be called once per animation frame?

Thanks,

Hi!
Thanks for the report, We'll check if there are any issues with this function and will let you know about the progress.

Hello.
We are gonna optimize this API in near future, thanks for your feedback.

Ok Thanks alot.
