Rhino Toolbar macro to rotate environment map

[mnewberg]

It has been requested to add a button to change the environment map direction via button press.

Below is a rhino toolbar macro to rotate the vray environment. Feel free to adjust the comments for left/right rotation/prompt.

Sub RotateTexture(settingUrl, param, dblOffset)

	Dim VRay

End Sub


Dim dblOffset

dblOffset = 3
'dblOffset = -3
'	dblOffset = Rhino.GetReal("Angle to rotate the offset", 45)

RotateTexture "/SettingsEnvironment", "gi_tex", dblOffset
RotateTexture "/SettingsEnvironment", "bg_tex", dblOffset
)

Not tested yet, but I like the idea. Could it be possible to load the environment to the Rhino environment with the same settings? Than the env turn could be seen at the viewport.

At the moment the env can be seen at the viewport, if Vray is disabled as renderer and the env editor is be used to set the HDRI as background and than Vray can be enabled again. A long way and it seems to be that Rhino provide all necessary code.

What textures are rotating ? The ones for skylight and reflection/refraction(background) environment vray options tab, right?
I un-commented the rotate dialog but I accept the default of 45 dg but the texture rotation doesn't seem to change ...




Could this be done for an hdri loaded in a vray dome light ?
I hope that vray 3.0 supports viewing of the environment in the viewport ... too much guess work right now

For this script what we are changing is the offset, which is basically the same as the rotation.
