Hey everyone! Today, I'm going to show you how to use transform geo with OBJ files in Nuke for some epic 3D compositing. Let's dive in!

Step 1: Import Your OBJ File

First things first, make sure you have your OBJ file ready to go. In Nuke, select the 'ReadGeo' node and load your OBJ file. This will bring your 3D model into the Nuke environment.

Step 2: Add a TransformGeo Node

Next, let's add a 'TransformGeo' node to the scene. This will allow us to manipulate the position, rotation, and scale of our 3D model within Nuke.

Step 3: Adjust Transformation Parameters

Now that we have our TransformGeo node in place, we can start adjusting the transformation parameters to position, scale, and rotate our 3D model as needed. Play around with the values until you achieve the desired look.

Step 4: Connect to Your 3D Scene

If you have a 3D scene in Nuke, you can connect your transformed OBJ file to the scene using a 'Scene' node. This will integrate your 3D model seamlessly into the overall composition.

Step 5: Fine-Tune Your Compositing

Finally, spend some time fine-tuning your compositing to ensure that your 3D model blends in seamlessly with the rest of your scene. You can use lighting and shading tools to further enhance the realism of your 3D model.

And there you have it! By following these steps, you can effectively use transform geo with OBJ files in Nuke to elevate your 3D compositing game. Give it a try and let me know how it goes in the comments! Happy creating!
