ボリュメトリッククラウド:建築家のための簡単な空の置き換え

Often, the issue lies in a static, 2D sky that acts more like a "sticker" than a physical environment. To add depth, you need a system where the clouds are part of the lighting. Shifting to Volumetric Clouds—a core part of D5 Render 3.0—allows the sky to catch light and cast shadows realistically. This creates a natural, "grounded" feel between your building and its surroundings that a flat image simply can't replicate.

The most efficient approach is to handle the sky directly within your 3D workspace. By using D5 Render's Volumetric Clouds, you can refine the atmosphere in real-time, which handles the color matching and edge blending for you. This moves the workflow from tedious Photoshop layers into the rendering stage, saving you from having to fix lighting inconsistencies later in post-production.

It's a common struggle to balance a beautiful sky with a clean silhouette. We designed Skyline Mode in D5 Render 3.0 specifically for this. It lets you keep the "Zenith" (the top of the frame) clear while populating clouds along the horizon. This gives your architecture room to "breathe" while still maintaining a professional, layered background.

A "CG look" usually happens when the sky feels disconnected from the rest of the scene. In D5 Render 3.0, the clouds are synced with global environmental settings. When you enable 'Dynamic' mode, the cloud drift matches your vegetation's wind response. This unified logic ensures your entire animation feels like one singular, breathing world rather than a collection of separate effects.

Instead of manually layering multiple filters, you can use dedicated volumetric presets. In D5 Render 3.0, swapping to a Cumulonimbus preset instantly sets a heavy, dramatic tone. Because these are true 3D volumes, they interact with the sun to create moody shadows, helping you craft a fast-moving storm narrative without complex setup.

Achieving those organic, moving light patterns requires a sky that interacts physically with your light source. Within D5 Render 3.0's Volumetric Clouds panel, you can simply enable the Cast Shadow toggle. This allows the sun to filter through the 3D cloud layers as it would in reality, casting soft, dappled light across your site and facades. It's one of those subtle details that really grounds a project and makes a professional portfolio stand out.

This usually happens when the fog and sky aren't sharing the same lighting information. D5 Render 3.0 addresses this with a feature that syncs fog intensity with the skylight. As the sun sets, the fog darkens naturally to match the clouds. This synchronization "integrates" the atmosphere together, ensuring the ground and sky feel cohesive.

Let's be honest—hunting for the right HDRI is a huge time-sink. That is why many designers are shifting to the Volumetric Clouds in D5 Render 3.0 for the creative freedom they offer. Instead of being locked into a static image, D5 Render allows you "steer" the sky in real-time to match your specific camera angle. This ensures your lighting remains consistent with your sun position, no matter how much the design changes during the process.
