I just bought Ornatrix a few days ago,
I'm using " Ornatrix 6.0.8.15492 [Latest Stable] " with 3DSMAX 2017.

3DS MAX crashes when I try to edit guides with comb brush, and gives such error :

File: d:\teamcity\buildagent\work\cdf694efa24c5eef\ephere\geometry\native\Matrix.inl
Line: 271
Function: Ephere::Geometry::Matrix<3,4,float>::LookAt
Expression: Assert failed: Ephere::NearEqual( directionLegnthSquared, T( 1 ), T( 0.000001 ) ), Vector [-0.173363, -0.853, -0.492278] has length squared 1, which is not close enough to 1

What am I doing wrong ?
