Diablofans.com picked up some recent information using their Diablo Development Tracker about lingering graphics in Diablo 3. It starts out with Bashiok answering a few of the questions, and as the conversation intensifies he brings in Lead Artist Julian Love to help answer the questions about blood and bodies and just how long they'll stick around!
Here's what the Diablo Dev Tracker picked up:
A user from Battle.net recently inquired about whether or not blood from battles could be kept on the ground indefinitely in Diablo 3. Bashiok was quick to respond with an initial explanation:
Regarding visible markers, we put a lot of effort into building rooms and areas to ensure that the randomly generated dungeons are indeed random, but also not confusing and maze-like. We don't want everything to look the same. So in that respect a visual marker of a blood spot or corpse really shouldn't be necessary."
After some Battle.net users pushed for more details, Bashiok brought in Lead Tech Artist, Julian Love, to give a more detailed answer to their questions:
So, that's a lot of words just to say that blood splats can be every bit as expensive as, and in some ways, more expensive than dead bodies. It's counter intuitive, but this is the way it actually works."
Hopefully that clears things up a bit in regards to the issue of having graphics lingering on the screen indefinitely.
