[SOLVED] The node's position had some translation after saving world!!!

[Tu.Xiaomi]

When I had completed my work, saving world.

 

tips.It is a huge world.3072 X 3072

 

The next time I opened the same world, some node changed their position about 1~3cm.

 

How to fix this.

Hi,

 

Step by step instructions will surely help us to get to the root of the problem faster.

Also If it's possible, a simple test scene would be very helpful.

 

Thanks!

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.

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?

Yes, this is the problem.

Sounds like floating point precision isuues, you should use Unigine double-precision build to see if this resolves the problem.

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.

This bug is fixed in Unigine 2.0-beta.
