Normal maps for cc5 crash unreal 5.6
Hi... I did alottt of testing.. and almost all my characters that were working JUST fine with cc4 exports to unreal thru iclone LLink, now do not... they crash unreal EVERYTIME... after alot of tests with several characters i was able to track the issue to the head normal map... if i remove from cc5 the head normal and save as avatar and open in iclone 8.6 and export thru llink to unreal 5.6 the characters work... again this was NOT an issue before..

I even did the whole save head and body as morphs ans then using the HD Neutral mesh to port my custom characters to cc5.

Hi Allen..

Just take this character from cc5 into iclone 8.6 and then thru the livelink, TRANSFER it to unreal 5.6... after a while you will see unreal crash like in the video

https://drive.google.com/file/d/15M6AtIfd2rU6FZA_ge7dBuBB43yqfrGm/view?usp=sharing.

and now ANOTHER issue i found... custom clothing that are displaying very well in cc5 or iclone.. where exported to unreal 5.6, it will lose their IDs and the materials of the character will be transferred to it also...
