Here is the first result for Lagoa:
Lagoa features MultiOptics, the world’s first photorealistic interactive 3D renderer on the cloud. My current workflow with Lagoa is to export OBJ files from within Blender, upload those (and textures used) to the Lagoa web site, apply materials there, and render. Here a couple of things I came across:
You have to be careful about the normals, otherwise you might end up with black parts in your scene where the normals point away from the camera. You can actually see some black parts on the wooden bath tube, where the normals were not corrected.
Matching Lagoa's camera with Blender's camera is tricky. I would assume that you can use the camera position and the positon of an empty, which you used for auto-tracking within Blender, but that didn't work correctly. So I just tried to match the camera closely by navigating in the browser and comparing with other images rendered by various renderers (see post here).
The materials need more attention. The rendering I got so far doesn't show the specular reflections (e.g. in the wooden parts) yet.
What's nice about Lagoa is that you can start rendering in the browser/cloud (not on your local machine) and while you adjust materials you see the results immediately.
I did have some problems though sending the render job into the background and picking up the resulting image later. I waited for example two hours to let the render refine and the resulting image showed some black parts, whereas it rendered fine interactively in the browser. It would be helpful to be able to see the background job rendering (I mean the image, not just the time slider).
