need help with the size ingame and into blender.

[ProvencalLeGaullois]

I have a problem with the size of the meshes. When I import a collada into blender I get something very small. I imported some collada files from 0ad to get a good idea of what size my meshes should have. When I export my meshes I get something really small in 0AD. Someone can give to me some tips ?

Yes. Use the "very small" size reference that the imported.models have, but before exporting something into the game, use ctrl+a and select apply scale

You can also edit the dae in a text editor, and change the unit of measurement to meters (one of the first few lines). The engine expects everything in meters, while while blender reads that unit, but exports it in some default unit.

yeah... I forgot to do ctrl+a, but that wasn't the problem, I didn't use scale and rotation, I made everything in the editor mode. Even if I do it, I got the same problem

I make a try, sizing a cube to 1m³ in blender, and ctrl+a, I got this in Atlas :

looks like 1 meter is more like 1 «big» feet...

it's not possible to upload dae file, I put everything between code balises :

meters are just game units. Our soldiers are over 2 meters in height (more something like 3m). While on the other hand, buildings are scaled down. Just to fit then all on a map.

If you put the unit of measurement to meters, it should really work.

[ProvencalLeGaullois]

well, I see in blender that an imported collada isn't at scale 1 (I didn't noticed that before...) I implicitly thought it was at 1, then all my scale factors were wrong.

now I can work with a "dummy" having the scale I want and just calculate a factor to get a good size in 0AD.

thx everyone!
