Mirrored groom and reversed tip-root points problem

[bolekcg]

Hi Guys.

 

That's the first post of mine so at first thank you everyone for spending time and such a great effort for sharing knowledge. That's what i really appreciate !

Anyways ... lately started my journey to houdini and as I'am grooming/fur guy i started with my profesion thing in houdini ... and it lasted ... about hour to wonder how to go further   so question goes below.

 

I did pretty simple ear fur and wanted to mirror it so as follows i removed one side of guides , then mirror proper one (adjust position) then i did ray node for sticking root point to surface and then i used merge and i tried guidegroom again to adjust it a bit and demirror look of it . And here's the problem ... roots are considered as tips on those mirrored guides ... i tried reverse and some other things but i don't know if that's a bug of mine or if that's a feature

 

Thank you very much in advance!

I found out that i used mirror node with "reverse normals" on. Switching it to NO helped me out !

So another question related to mirroring namely ....

Which internal attribute is related to "max guide angle" attr. on hairgen node? and how make mirrored guides as they were generated from surface (not mirrored ). How to ... kind a reset them ?

 

When i'm using mirror it seams that guides holds info about it's previous positions (somehow ... don't know how and where) and i need very high "max guide angle" to cover it with fur

 

WHILE

 

When using very similar guides but without mirror "max guide angle" works well

 

 

Thanks once again in advance!!
