scene orientation, Z up?

[varomix]

Hi guys

I'm trying to build an exporter but my scene seems to be on it's side

does Vray use the Z axis up? 3dsmax style I guess

if so, are there any known solutions for this, since maya uses Y up

thanks

Hi,

Have you tried to export a 'SettingsUnitsInfo' plugin?

Here are the parameters for this plugin:

Parameters for plugin 'SettingsUnitsInfo'
  meters_scale: float = 1, The number by which a 3d distance must be multiplied to covert it into meters.
  photometric_scale: float = 0.001, The number by which the power of photometric lights should be scaled when rendering.
  scene_upDir: vector = Color(0, 0, 0), The 'up' direction for the scene.
  seconds_scale: float = 1, The number by which a scene time unit must be multiplied to convert it to seconds.

In the exporter in Maya we use (0, 1, 0) for the scene_upDir.

hint: To view the parameters for a particular plugin type you can use the plgparams utility.

that's great news
can I use this plugin launching a render from the standalone renderer?
cause that's what I'm using

thanks

ok I found out that I can do that in the vrscene file which is awesome to me, but, can't make it work

I'm using this and I cant see any difference

SettingsUnitsInfo {
scene_upDir=Color(0, 1, 0);
}

help

scene_upDir is actually a vector, not a color so it should be

SettingsUnitsInfo { scene_upDir=Vector(0,1,0); }

but even so, this will not automatically flip your scene - you'll have to make sure your camera transformation is also correctly flipped. SettingsUnitsInfo is used by some plugins (like the V-Ray sun and sky) to determine their orientation.

Best regards,

the plgparams utility says it's a color, I tried a vector also but no luck either

so, what do I need to flip then, just the camera?

thanks

It says it's a vector, but mistakenly lists the default value as a color. In any case this will not affect your scene flipping in any way, like I said.

Both the camera, and the up vector (like I explained, the latter will be used for sun/sky etc).

Best regards,

That sounds way better then flipping every object

thanks
