obj file export

Post by Stav2se »

Hi,
First of all I would like to congratulate you on this brilliant software.
I have a small issue with saving as obj file. I have an object file which needed relocating to its real geo location; which your software brilliantly did.
Although the problem is that once I save the relocated object file as .obj it comes up like very pixelated and the faces look like they have been stretched; while the original file is nice and crisp.

Do you know where the problem lies?

Warm Regards,

Stavros

What version of CC are you using? Recent versions should save the coordinates with a precision of 8 digits which should be enough to keep the original precision even with large coordinates (you can check this by opening the OBJ file with a text editor and look at the vertex coordinates - lines starting with a 'v'). If it is not, I could increase this to 12 maybe?

Another potential issue: are you looking at the resulting OBJ file with CC or with another software? (not all the software handles large coordinates correctly).

Ok forget it, I realized that there was a kind of glitch in Qt (setting the output precision to 8 was not enough to make it write numbers with 8 digits contrarily to what the documentation says ;).

I've updated the online beta version (2.8.beta).

Hi Daniel,

The good news are that the precision of it is now fixed, but the problem is still there. It looks more like that faces are randomly located around the vertices. I dont know how to explain it.

Is there any way I can send you some pics of the example. Sorry to be a pain and thanks a lot in advance.
