GetUvData always returns 0.0 for rotation instead of the correct value
Hi,
When I call the method:

material_component = avatar.GetMaterialComponent()
material_component.GetUvData(mesh_name, material_name, texture_channel, uv_offset, uv_tile, uv_rotate)

uv_rotate always returns 0.0. I am able to set the rotation value with the method: AddUvDataKey successfully though.

I would also like to point out that your API documentation for the method:AddUvDataKey on your site is wrong.

On https://manual.reallusion.com/iclone/script/python/class_r_l_py_1_1_r_i_material_component.html it reads:
...
material_component.AddUvDataKey(RLPy.RGlobal.GetTime(), mesh_name, material_name, texture_channel, uv_offset, uv_tile, uv_rotate)
...
def RLPy.RIMaterialComponent.AddUvDataKey ( self,
kTime,
strMeshName,
strMaterialName,
eChannel,
kUvOffset,
kUvTile,
fUvRotate
)
...

But in fact the first parameter to this method is: kKey [IN] The key for time and transition control - RLPy.RKey
This is correct on the Wiki though: http://wiki.reallusion.com/IC_Python_API:RLPy_RIMaterialComponent

Hi Allen,

I've tested this successfully but it does not align with the documentation:
...
kUvOffset [OUT] uv offset - RLPy.RVector2f
kUvTile [OUT] uv tile - RLPy.RVector2f
fUvRotate [OUT] uv rotate - float

Return Values
RLPy.RStatus.Success Success.
RLPy.RStatus.Failure Fail.

Is that going to change in future or stay like that? Is the out parameter uv_rotate used for something?

Thanks for your help.

Cheers,
Martin

Hi Martin,

About GetAVData API how to get uvrotate, you need to get from the value returned.

As below code:

return_values = material_component.GetUvData(mesh_name, material_name, texture_channel, uv_offset, uv_tile, uv_rotate)
uv_rotate = return_values [1] # this is the uv rotate value returned


And thank you for pointing out that the AddUvDataKey function description in our API documentation is wrong.
