Thanks for the scene. I'll check it this weekend

Thanks,

Yes, it seems that there is a problem with the FFX objects transformations stack when they are parented to bones. I'll investigate it ...

...yes spooky and if you parent it on another bone in the hirachie from time to time he render the hairs "but without the deformation from the bullet"...ok thanks

hi juanjo

any news about the ffx issue? can you fix it?

Not yet, sorry. I'm still investigating this issue. The problem is that I can't reproduce the problem using a small, simple scene, and I'm not sure why this problem happens in your scene.

I hope to know more soon.

tipp. if you not use ffx and for example the option "enable polygonal hair" (octane properties option) octane also can not see the geometry from the bullet deformed splines and render exact nothing)...spooky...

After long hours of tests, I'm afraid that I've good and bad news. The bad news is that this problem is related to a bug in LightWave 2015, in the FiberFX API, and I can't find a workaround for it. The good news is that this problem has been fixed in the next version of LightWave.

Sorry, but the FiberFX API can't compute currently the transformations related to attaching the fibers to the bones chains and other hierarchies. I've tried several tricks, but without luck so far. If I find a solution, I'll let you know.

a workaround is to record the pivot data from the bone and give that data 1 to 1 to a null object or direkt to the hair bundle. than you can unparent the hair bundle from the bone and the hair bundle or the null make the same moves and rotatings and can be rendered.

i know. that bug is from the first version of FFX included. it works also not with lw native.

" If I find a solution, I'll let you know."

thanks. there are some workarounds with record the bone data and transfer it to the hair bundle or a null and parent than the hair bundle on the null. in that case it would be rendered.
