Light and Shadows in opensim

No comments

I have been using Imprudence and Kirstens viewer in opensim for some time. Kirstens viewer is what I use for video and photos. I use the S19 viewers with shadows enabled. The latest build is a little shack in Troppo Club a 3×3 Diva distro grid. Shadows and the way a viewer handles light is fun and challenging and way different to photography in RL. The ability to control the time of day and East angle of sun and moon light is handy, in Opensim this works really well. Add that light (lets call it natural light)  together with projected light (works in Kirstens but not in imprudence yet )and you have a big say in how your video or photo will look. Projected light is light from a prim but unlike “a prim like a light” only projects light from one face of the prim (my understanding of it) you can give that face a texture say a circle and that will then become a spotlight. I will show some photos from the project I am working on right now in the next post to explain more.

Here are some photos of the latest build to show what Kirstens and Imprudence can do. The photos with fake shadows (shadows on a prim still hanging around ) are Imprudence the others are Kirstens no projected light was used in the photos this time.

We are still testing and playing with the light and shadow effects in OpenSim using Kirstens s17 viewer.

What do we think so far? We love it! No if’s no but’s!

Problems yeah we always have problems a day without them means we haven’t tried hard enough :-)

We had some corrupted prims maybe?, We think that was the problem happened to a few roofs light was streaming in, in places it should not let light in. Deleting the prim and adding a new one fixed that.

Prims that have been cut or hollowed we have had problems with them so we have replaced them with whole prims.

Of cause transparent texture is just that transparent and do mot cast a shadow so our blinds are now made of prims.

We have some nice looking trees and plants that we haven’t worked out how to use. We have at times used an old linden tree or fern together with them to cast a shadow, companion planting :-)

Light as you can see in the photos adds depth to the picture. All of a sudden we have a lot of control, that makes the environment more complex but that is exactly what we wanted.

What once was an exciting world is now even more exciting. OpenSim really is very good.

The vase only has a Blank added as texture so all the shading is dynamic  how good is that ?? All photos taken as snapshots .jpg high res only cropped no other editing
