BSP is by far the best scene management system for hardware accelerated systems
I think the problem is that I'm talking about levels with large amounts of arbitrary geometry.. in this case BSP is not a good solution is it?...unless you have to construct your levels out of simple shells, with meshes inside them all.. this would be a big pain...

oh ok... I just thought BSP calcualtions didnt work with concave geometry and so forth...
Yeah, same here. I always thought BSP was convex only, and quite outdated because of it.
Which makes me wonder, why not sooner? Why will BSP allow concave eventually with A7 and not with A5, A6? Why the time for developing an Octree/ABT for concave if BSP would have allowed it all along? I think if BSP allowed seamless geometry of all types, many people would be drawn to it regardless of the longer compile(if it really does have a much better speed difference). This would also make BSP more newbie friendly due to the elimination of convex only geometry. Not that it's terribly complex anyways. Probably most who started with Gstudio started by building all kinds of convex levels in WED, more advanced users may eventually switch over to Max, Lightwave, and create everything there. Because of this, they'd most likely require concave geometry anyways(ABT) and of course, good scene importers that import both models(so you can apply actions to certain objects) and geometry.
If Gears of War is BSP based, it surely doesn't use convex geometry for everything. Only programs like Max and Lightwave can create these types of meshes, and these mesh's are arbitrary. WED wouldn't be able to develop similar levels, because it's tailored for convex levels.

Well there is my 2 cent (descent). "From its very nature, BSP is a Pro feature" Being a customer for 5 years and I've always had BSP not 100% happy about it been taking away if I don't upgrade to Pro, love U Conitec but I need to say this  From the above posts, I think you are saying that BSP will work with arbitrary-shaped geometry. Quote:
"import any arbitrary-shaped geometry and the BSP tree will still work."
So does this mean that we are removing BSP blocks, if not will shaders work fast on BSP blocks.
I'm still thinking about upgrading to Pro but I have to think about it hard, $1000 is a lot of money (after exchange) to spend, it would be nice to see the different packages planned for A7.
But I still can't get out of my mind, that if I spent $1000 elsewhere on a engine, I would get great shaders out of the box like
Unity Engine
I do want to stay with 3DGS and I know that a list of shaders are coming in templates, but it feels like they have been coming for years

Hey Doug
So you are saying that the A7 Pro BSP has been rewritten and will be faster then the A6Con BSP engine?
I wish JCL would show a specification list for A7, it would help people like me who are thinking about upgrading to A6Pro now.
A7Com is not losing shader editor or anything else is it?

The BSP feature that the Pro owners are getting isn't the same as the one that ABT replaced in A6. The A7 Pro BSP can use arbitrary-shaped geometry, work with ABT, etc. The downside is that this new BSP is a lot trickier to use right than the base ABT system. Thus, Pro only.
sounds interesting. i thought a7 will just keep the old bsp system around. but why will it be trickier to use right? could you go into a bit more detail?
and maxf's question about bsp + shaders was a good one too.
