removal of arbitrary limits?

Post by MrMunkily »

are there any plans to remove some of the arbitrary (I assume, but I guess that they might be there for a reason) limits in blender, such as only 256 lights at a time??

Who in the name of ton(excuse the bad joke(s)) uses more than 256 lights in a scene????

the vertex limit needs to go though!!!

This guy did
(rendered with POV-Ray)
All the objects in the scene are white and he used lights to add color to the scene. It is an interesting effect.

I'm specifically wondering about the annoying tricks needed to pull off HDRI and GI in blender with lightdomes. Also, the vertex limit most certainly needs to go.

arbitrary limits suck.
just ask larry wall.

Hey, at least everythings in powers of two (If you start from zero) :wink:
Seriously, this is true. Also, what is the vertex limit? I have a feeling I've reached it bfore, and that blender segfaulted rather than complain gracefully.
Increasing limits or making them unlimited, could be non trivial, like replacing arrays with lists that can grow. This also makes the program slower, since it requires dynamic memory allocation instead of static. Its probably the right thing to do in many cases.

Vertex limit is 2^16 8)

(or 65536)

I seem to remember that the upper limit for total verts/scene was increased a couple of times. I don't know if those changes were non-trivial or not, but I can only assume that memory allocation for vertex lists etc is dynamic already. I mean, it would be very weird if an empty scene would claim a huge heap of memory and then fill it up as you go...

Edit: just a spell check =)

I´d like to get rid of the normal length limit, which is 2.0, or am I missing something and it can be set larger?
