Wie verteilt man 3D-Animationen effektiv?

Also understanding each formats pros and cons. For example, obj is a much more generic format than fbx and tends to load faster and be more common, but fbx can store data like cameras, lights, animations. If you're just making a simple static mesh you wouldnt opt to save it as an fbx since it wouldn't contain any of those other atributes like animations or light.

Pack them into a FBX or GLB/GLTF. Apply draco compression(decide on lossy or lossless according to your needs) to GLB/GLTF to reduce the size your file occupies on the disk drastically (Make sure the place you're transferring the files to supports draco gltf import else the import will fail). Pack your textures in jpg and not png as much as possible. Save jpg with upto 25% reduced quality if it works fine for your visualization needs.

OBJ format can save the 3D model but cannot preserve the animations. Whereas FBX and GLTF format can help in preserving both model and animations.

In my experience, I always prefered .Obj over any format, Its a hassle free process and it's universal with all the software that i work with.

Professional 3D artist with expertise in Cinema 4D, Unreal Engine, and After Effects. I adopt a meticulous approach, exporting models in OBJ, and employing FBX and GLTF for comprehensive materials and animations. Cineware integration ensures a seamless transition between platforms. Unreal Engine utilization includes FBX for material and lighting adjustments. In After Effects, I exercise control over color grading, motion, and visual effects. Final projects are rendered in MP4 or MOV, with flexibility to segment into reels, shorts, or GIFs as per client needs. A cohesive workflow ensures professional execution, meeting creative and client-specific demands.

Another thing to take into consideration is applying techniques like baking complex details to a lower poly model and understanding and making proper use of tensel density.

In my workflow, I strategically incorporate Cineware for baking, ensuring optimal results for specific camera movements and low-poly considerations based on model shape and animation dynamics. The meticulous selection of high-quality materials and textures contributes to superior rendering output. Notably, I leverage the real-time rendering advantage of Unreal Engine by adopting a medium resolution approach, aligning with the engine's capabilities to deliver impressive visual outcomes. This method ensures a harmonious balance between efficiency and high-quality results in the realm of real-time rendering.

Before export, computationally slow animations such as deformation systems should be reduced to vertex animation saved as point caches. The same is true for particle animation and physics simulations like cloth and rigid body collisions. These also need to be baked into a cached form. This speeds up real time performance both for review and for pre-visualizations in a rendering engine. Reducing the computational load also makes a 3d scene compatible with a wider range of 3d applications from other software developers.

Techniques that compress geometric meshes and point cloud data at a low level can provide superior compression compared to standard file compression techniques. An instance of this is the use of the Draco compression library for converting GLTF files to GLB.

In 3D animation, effective compression is vital for file size optimization. This involves encoding animations to reduce data without compromising quality, utilizing methods like lossless or lossy compression with algorithms such as ZIP, JPEG, or H.264. Software tools like HandBrake and online platforms like TinyPNG assist in this process. By aligning compression methods with animation specifics, the user ensures efficiency in storage, upload, and download processes. This approach aims for a delicate balance between reduced file size and sustained animation quality, adhering to industry best practices. The adoption of this compression methodology demonstrates a commitment to delivering visually appealing and practical 3D animations.

Before working on a complicated project, making a small version and testing it in advance can save you time and work. For example if you want to know how the texturas would look on the final product, maybe exporting a very simple polygon with some textures and comparing the colors and lighting can give you an idea of how a more complicated model would look after you export it. It wouldnt be fun to work on something for weeks just to find out you have to remake a large portion of it, if the textures where off for exhample.

Before releasing 3D animations, thorough testing on diverse devices and platforms is crucial. Ensure compatibility, responsiveness, and consistency across browsers, operating systems, and screen sizes. Tools like BrowserStack aid in comprehensive testing, ensuring optimal performance. Seeking feedback from peers, colleagues, or clients on how the animations appear and function on their devices is invaluable. By adopting a meticulous testing process, the user showcases commitment to delivering a seamless and universally accessible 3D animation experience. This approach safeguards against potential issues and aligns with industry standards for quality assurance.

Your exports should be as high quality as possible. Starting from high quality allows you to adjust animation compression, texture compression and LODing on import into a given engine. I saw a couple of mentions of using jpg. Do not use a lossy format for anything. Furthermore, jpg will change the gamut of your image. Saving disk space is not the same as saving in-engine memory. Don't believe me? Open a high frequency image (not a jpg) and save as a jpg. Paste it as a layer over the high quality source image and diff. What is left is what jpg compressed out of the original.

Selecting an effective delivery method for 3D animations involves weighing options like email, cloud storage, social media, or streaming. Tailor the choice to your specific needs and preferences. Email and cloud storage, like Google Drive or Dropbox, excel in private sharing but may pose limitations on file size and download speed. For broader or public audiences, leverage social media or streaming platforms such as YouTube or Vimeo. While these avenues expand reach and encourage engagement, they do come with constraints on file format and quality. Thoughtful consideration of these factors ensures a seamless and impactful distribution strategy for 3D animations.
