Introduction

Welcome back to the Second part of our tutorial series. In this series, We Are exploring how to bring Stable Diffusion images and deform animations into Unity VR with the help of Touch Designer.

Setting up the Skybox in Unity

In Unity, we have constructed a cube that serves as our Skybox. We use a plugin called Spout to capture an image stream from Touch Designer and store it locally in Unity as a render texture. Each render texture is applied to a material and then applied to each side of the cube. In this tutorial, we will focus on the three faces of the Skybox that represent the field of view of the headset.

Animating the Deform Animation in Touch Designer

In Touch Designer, we start with one of the faces of the cube and composite a deform animation on top of it. We use a null to represent the image and connect it to the movie file in that contains the face image. We then Create another movie file in and add our pre-created deform animation to it. We set the parameters of this movie file in to control the speed, loop crossfade, and interpolation of frames. We also set the override sample rate and keep frame settings.

Compositing the Animation in Touch Designer

To composite the deform animation onto the face of the cube, we use a levels node to invert the depth map and make adjustments. We then use a blur node to soften the edges of the mask. We create a matte node to mask out the background pixels and create transparency. We use a composite node to Blend the deform animation with the background image. We adjust the parameters of the composite node to position and Scale the animation.

Blending the Animation in Unity

In Unity, we break the original connection between the left face image and the spout node. We connect the composite image from Touch Designer to the spout node, which updates the left face image in Unity. This allows us to blend the deform animation with the background image in the VR environment.

Testing the Animation in VR

Inside the Oculus Quest headset, we can see the blended deform animation in the Unity project. This provides a proof of concept for how we can seamlessly blend deform animations into the 360 environment. In the next part of the tutorial, we will focus on creating real-time deform animations inside the Unity environment.

Creating Real-Time Deform Animations in Unity

Next, we will start creating deform animations in real-time within the Unity environment. We will explore different deformations for elements such as vegetation and sea life, including octopi and jellyfish. We aim to bring the entire environment to life by animating various elements and enhancing the immersive experience.

Adding Vegetation and Sea Life to the Environment

In this section, we will focus on adding vegetation and sea life to the environment. We will animate elements such as plants swaying in the Water and fish swimming around. By carefully crafting these deform animations, we can provide a more realistic and captivating experience for the user.

Creating Real-Time Deform Animations for Mermaid Characters

Finally, we will explore the creation of real-time deform animations for mermaid characters. We will animate the mermaids' movements and interactions within the 360 environment. This will add a dynamic and engaging element to the VR experience, allowing users to interact with the mermaids and immerse themselves in the virtual world.

Conclusion

In conclusion, this tutorial series has provided an in-depth exploration of bringing stable diffusion images and deform animations into Unity VR using Touch Designer. We have covered the setup of the Skybox in Unity, animating and compositing the deform animation in Touch Designer, blending the animation in Unity, and testing the VR experience. We have also discussed the creation of real-time deform animations for vegetation, sea life, and mermaid characters. By following these steps, You can create immersive and visually stunning VR environments.
