Photogrammetry: Macro-environment in CRYENGINE

CG-artist Simon Majar shared some assets for an exclusive photogrammetry demo for CRYENGINE. A great opportunity to have a look at how this 3D scanning technology works.

The demo assets are absolutely free and available for download at CRYENGINE forums. The files feature a very detailed look at the scanned piece of environment and give some insights on the way the whole process works. Te detailed description of the scan is available in Simon’s official blog.

I used Agisoft Photoscan to make the model and textures. Medium settings, with my 8gb of ram, not possible to generate a really dense point cloud. I’ll try later with a more powerfull computer. From that model I generated two 8192px textures. The rest is easy, export and integrate to the CRYENGINE. What I didn’t do, and should have been done, is delete every lighting information in the textures. I’m still working on a proper way to do it. It’s quite complicated, and the best way to do it is capturing the environment to have an HDRI. But I don’t have the equipment yet, just a middle class camera.

As a result the demo has baked lighting. In the video the camera is actually not moving. Instead the level itself is turning around.
