Hi,

I have an user channel with a calculated Y rotation angle (float, 0…360) and I want to plug it into the texture Y rotation of an Octane material. But I get always an „invalid pin“ error.

How can I use my rotational value in a texture rotation?

(I have an animation what turns my mesh in the Y axis. And I have an schematic that is correcting the texture rotation so that the label is always in the front. And I need this correction as a texture Y rotation in my Octane material.)

Hey there,

watch this video https://docs.otoy.com/ModoH/ModoPluginManual.htm#Modo/PluggingModoNodesintoOctane.htm

You have to create a "octane float value" rightclick, choose "add channel" and add a xyz float input. Then you can connect your Modo channel to the Octane Float Value node and this node into a transform node.

I hope that helps!

It does not work. And the video does not help unfortunately.

The Modo angle comes from left.

Try the attached scene.

You need to use a transform which expects float values. I used the 3D transform.

You can also use the modo texturelocator via the octane projection. I attached another scene

The reason your example is not working is because you have exposed the Rotation X, Rotation Y and Rotation Z pins, however connections from an Octane Float Value and individual pins from an Octane Transform Value are not supported. Instead, use the Octane 3D Transform and plug your Octane Float Value into the "Rotation" pin.

Instead, use the Octane 3D Transform and plug your Octane Float Value into the "Rotation" pin.

Okay, this pin is not invalid. But the position of my texture is lost totally. I tried to modify the position, rotating and the scale of the texture, but I can not find it again.

Is there a way to show the Octans texture locater position?

I already use the Octane spherical projection. I will take a look to Your scene files. Thank You.

My original texture has a Y position of 653 mm. When I use 3D transform and put in 653 (mm is not possible here) than I can’t see my texture. Is is possible that Modo and Octane are using different units? Perhaps I have to calculate the Octane units for 653 mm.

I can not find any information about this in the manual:

But I found two little typos in the blue boxed text (too many hyphens):

Code: Select all

… use the Tex- ture Locator …

Code: Select all

… connect a Modo Texture Loc- ator to …
