Tools like Houdini, Substance 3D, and Blender have long been staples in the 3D designer’s toolkit. However, the emergence of AI has ushered in a wave of innovative 3D tools that aim to speed up and simplify the creation of 3D models and fit seamlessly in with the existing tools in a 3D designer’s stack.

Imagine starting your design process not with a blank canvas, but with a textual description that instantly transforms into a 3D model. It’s not just about efficiency; it’s about reimagining the very way we approach design.

But as any seasoned 3D designer knows, the initial model is just the beginning. Refinement, customization, and enhancement are crucial to achieving a final product that truly resonates. That’s where Blender comes into play. Together, Alpha3D and Blender can offer a seamless workflow, allowing designers to generate models from text and then dive deep into the intricate world of 3D design.

Alpha3D: A new tool in the 3D designer’s arsenal

At its core, Alpha3D is a generative AI-powered platform that creates 3D models from text or image inputs. But what does that mean for a 3D designer?

It’s not about replacing the intricate craftsmanship of design but enhancing it, giving designers a head start in their creative process. For many 3D designers, the toolset is diverse, with different platforms catering to various needs of the design. Alpha3D fits right into this ecosystem, creating an initial 3D model that can be further refined and enhanced in tools like Blender. The ability to export models and use them on other platforms ensures that designers have the flexibility they need.

Blender: The 3D designer’s playground

Blender, with its rich feature set, offers a plethora of tools and techniques that can elevate any 3D model. For 3D designers, especially those working with AI-generated models from Alpha3D, Blender provides the perfect playground to refine, enhance, and truly make a model come to life. Moreover, its enhanced support for complex materials and lighting ensures that designers can achieve realistic and high-quality renders.

How to create a 3D model using Alpha3D and Blender

One of the key benefits of using Alpha3D in tandem with Blender is the optimization of the design workflow. Starting with a text-generated model from Alpha3D provides a solid foundation, allowing designers to focus on the intricate details and enhancements in Blender.

For this article, we’re going to use a text prompt – “cherry” – to generate a 3D model of a cherry with Alpha3D. We will then import it into Blender to give it some final touches.

Here’s how:

1. Generating a 3D model from text and exporting from Alpha3D: Firstly, we generated a 3D model from a text prompt with Alpha3D and downloaded the 3D model in glb format to ensure compatibility with Blender.

2. Importing the Alpha3D generated 3D model into Blender: Simply navigate to the ‘Import’ option, select the appropriate file format, and your Alpha3D model will be ready for refinement in Blender.

3. Editing and customization: With the model imported, we can now refine and modify the 3D model.

Firstly, we’ll clear all transforms to ensure that the scale, rotation and position are correct.

Moving on we’ll go into “Edit Mode” and select all vertices by pressing “A” on the keyboard and then “Alt+M” to merge all the vertices by distance. In other words, we have to make sure the geometry is one solid object without any holes or doubled vertices.

The next step is to delete any unnecessary parts that might look broken due to the model generation process.

With the help of sculpting brushes like Grab, Inflate and Smooth we can fix the problematic part such as the stem of the cherry.

While we’re at it, let’s also give this green blob a little smooth brush fix…

…and paint it red with Vertex Paint tool.

Once we are happy with the results we can proceed to export our model as .glb file and use it in any 3D environment or viewer.

Advanced methods for 3D model modifications in Blender

Detailed sculpting and mesh refinement:

• • Dynamic topology: This feature allows designers to add detail to specific areas of a model without subdividing the entire mesh. It’s particularly useful for adding intricate details to characters or organic shapes.
  • Multi-res sculpting: For those looking to add layers of detail, multi-resolution sculpting lets you work on different levels of detail simultaneously, ensuring a smooth and detailed model.

Advanced texturing and UV mapping:

• • • Procedural materials: Blender’s node-based material system allows for the creation of complex and realistic materials without relying solely on image textures.
    • UV unwrapping: With tools like ‘Seam Marking’ and ‘Live Unwrap’, Blender offers a streamlined process to unwrap your model and get it ready for texturing.

Rigging and Animation:

• • Armature creation: Designers can create a skeletal structure for their models, allowing for realistic movement and animation.
  • Weight painting: This ensures that the mesh deforms correctly when the armature is posed or animated.

Lighting and rendering:

• • Cycles and Eevee: Blender offers two powerful render engines. While Cycles is a ray-traced render engine providing photorealistic results, Eevee is a real-time engine perfect for quick previews and stylized renders.
  • HDRI lighting: Using high dynamic range images, designers can achieve realistic lighting and reflections in their scenes.

Particle systems and simulations:

• • Hair and fur: Using particle systems, designers can add realistic hair and fur to their models.
  • Fluid and smoke simulations: For those looking to add dynamic elements to their scenes, Blender offers robust simulation tools.

Optimizing for Performance:

• Modifiers: From the ‘Subdivision Surface’ for adding detail to the ‘Decimate’ modifier for reducing polygon count, Blender’s modifiers allow for non-destructive edits to optimize models.
• LOD (Level of Detail) systems: This ensures that models are rendered with the appropriate level of detail based on their size and distance from the camera, optimizing performance.

Conclusion

The world of 3D design is ever-evolving, with tools and techniques continuously pushing the boundaries of creativity. Alpha3D and Blender represent a harmonious blend of innovation and versatility. By starting with the intuitive text-to-3D generation of Alpha3D and diving into the intricate refinement capabilities of Blender, designers are equipped with a powerful toolkit that streamlines the creative process.

The post 2D image to Virtual Reality: A step-by-step guide to using Alpha3D with Spatial appeared first on Alpha3D.

Dominik is the 3D Lead at Alpha3D. He’s been working professionally as a 3D artist for over six years in the game development industry. He discovered his passion for 3D design early in university making first models for Unreal Engine and Unity projects just to pass programming classes, instead he fell in love with it and this love stays with him till this day You have to love what you do to be good at it! 

Dominik’ s first tip covers how to export your files in the right format for AR, including the necessary file types and how to easily export them. He also provides advice on how to test your 3D assets for AR using proper viewers and how to optimize their real-life scale. Finally, he discusses how to avoid “dirty” 3D models and the limitations of AR. Keep reading to learn more!

1. How to export your files in the right format for AR?

To properly view your models in AppleAR or ARCore for Android you need to export two types of formats: USDZ and GLB (or .gltf).

USDZ files can be used to display 3D models in the iOS AR Quick Look feature.

GLB is a binary file format used to store 3D models in the glTF (GL Transmission Format) format. It is designed for efficient transmission of 3D models and is supported by many 3D graphics software applications. GLB files can include textures and animations and can be used in a variety of applications, including VR/AR, games, and e-commerce.

You can export both files easily using the Substance Painter texturing tool. Additionally, if needed, GLB files can be exported from Blender and USDZ can be converted via Reality Converter on macOS devices using the previously exported GLB file. 

2. How to test your 3D assets for AR?

To easily check your GLB and USDZ models after exporting you have to use proper 3D model viewers.

To visually check GLB models you can use this viewer: https://modelviewer.dev/editor/. I use it on a daily basis for quick testing in our 3D team.

However, for testing USDZ files, it’s not as easy and straightforward for non-Apple users. If you do own an Apple device, all you have to do is send the USDZ file to your iPhone/iPad and open it in the Files folder Browser app. The built-in AR solution will automatically load your 3D asset in AR and 3D for you to test your model in AppleAR.

If you’re using Alpha3D AI-generator to make our 3D models, you can just use our in-app viewer before you download the files.

3. How to optimize USDZ and GLB files for real-life scale?

When testing your model in AR you have to make sure that the correct real-life scale is applied to your model. It’s recommended to always create your models with real-life dimensions, if they’re available. When you export both AR formats from Substance Painter tool, you have to make sure that your GLB model imported to Blender has the scale of 100x bigger than original dimensions. Don’t worry, that’s actually a good sign. Now you know that if your GLB is 100 times bigger, your USDZ will have the perfect scale. All you have to do now is to scale down the GLB model in Blender by 100x and re-export.

4. How to avoid “dirty” 3D models?

If you see some “dirt” or compression artifacts on smooth, glossy and metallic surfaces, you can easily get rid of them by changing only one exporting option in the Substance Painter tool. When your model is ready and good to go just choose the Export Textures option and in Output maps you will find the normal map compression type set to “8 bit + dithering” by default. All you have to do is switch to just “8 bit” to get rid of the dithering – the cause of your “dirty” model.

5. Know the AR file size limitations!

To ensure that any AR solution or web GL online viewer works smoothly on every device you have to take into account the limitations of AR formats. One of the most typical requirements are the polycount hovering around up to 100k polygons/triangles, texture resolution up to 2048 px per one texture set and file size not exceeding 10mb. If you tend to see that your model file size goes above the limit even though it meets the polycount and texture resolution limits, try to lower the normal map details intensity and contrasts on patterns in different channels, especially base color and normal map. That can help you keep the file size in the limit.
