A – you can delete the whole THUNDERCLOUD folder and replace it with the new one included in GMH2.6 install zip file.

Q- How Hair dynamic work in GMH2 ?

A – GMH2 hair style system is using Maya Hair System as its core so all Dynamic attributes is the same as Maya Hair system, you can assign Nucleus solver to it or using classic Maya Hair dynamic .

Q- I currently have one license for GMH2 and was wondering if we were entitled to upgrade to version 2.6 or if there is an additional charge associated with the update?

A – If you purchased GMH2 via 3DOcean then you could always re login into 3Docean with the email/account you used to purchase GMH2 then go to download section -> you will find the link to re-download GMH with the latest version.

Q- Why baked textures using only a single CPU? I am use GMH2.6.

A -As GMH is using Maya ‘s native mental ray bake tool to bake out maps so it is limited to just 1 CPU core, it might take a while to finish baking all 5 maps ( but not forever ! )

Q- I did get the hair done, but I have hard time to attach to the character.Is is not following the character ‘s head.

A -because the hair by default setting of GMH2 is always float around the base polygon during dynamic, you can just group the base polygon together and parent this group to a locator or head joint.

Q- My maya scene ratio is too large, resulting tube into GMH2.6 generated is so small, what can be the solution?

A -to increase the width of hair tubes, you can change the setting ” Width Scale” , ” Tube Width 1 and 2 ” in the Style system node itself. Or you can just change the global scale setting.
