As always, Forecast features can disappear at any time and never see the light of day. The "modern drag & drop" WED UI always vanished.

So the more light sources you use the slower is the rendering. This is similar for stencil shadows. More light sources mean less frame rate, so we only allowed one light source for stencil shadows.

Of course, yet many game engines support multiple shadow casters...why not let the user choose how many lights cast shadows? Good lighting effects are difficult to achieve without multiple shadows. Modern hardware can easily support several shadow casting lights (Doom3 has no set limit as far as I know, it just adds passes). I sometimes I am tempted to think Conitec decides to limit functionality because it believes it's users are ignorant (maybe they are right unfortunately). Sphere Engine--the premier A6 graphics plugin.

Yes, there are users who will fail but they will eventually catch on. While more lights and more shadows and more this and more that will slow things down, we aren't living in the year 2000 or the year 199X anymore. The hardware can handle it, and a wise developer is one that will allow this and other features to be toggled on/off in an options menu. H The ability of my player to cast a shadow from 80 different lights in a room should be my choice and not one that was made for me given there's no reason why this feature shouldn't exist. I know it used to be in Forecast, so it was at least on the table at one time, and IMHO it should be put there again and implemented sooner rather than later. Shenmue was doing it on the Dreamcast and that was almost 10 years ago (1999). My User Contributions master list - my initial post links are down but scroll down page to find list to active links

It disappeared when the Light Management section went away. Quote: That feature used to be in Forecast under Light Management.
