The model's position is over 10000.0 And when I moved the model, the unit was 1 meter, then the movement delta was 0.1 m, the modify action can't be down than 0.1 m. it was a precision problem, when the position x,y,or z was over 10000.0, the modify action that down than 0.1 m couldn't be applied, so two snapped model has space between them.

sebastianbah Posted January 28, 2015 Share Posted January 28, 2015 If I understand you correctly, problem is that the position value is rounded to a first fractional digit on a large distances. Is it so? Link to comment

ulf.schroeter Posted January 30, 2015 Share Posted January 30, 2015 Sounds like floating point precision isuues, you should use Unigine double-precision build to see if this resolves the problem. Link to comment
silent Posted February 2, 2015 Share Posted February 2, 2015 Hi, We found the root cause of this behavior. Unfortunately, float and double versions are both affected. Bug fix would be available in the next SDK update. Sorry for the inconvenience caused.
