I am very content with Havok 4 since I have it running on the sim, but in my opinion some things, f.e. unsitting kicks you up, should be really fixed before going public. I am very confident that you achieve that till then Good work done so far.

We have had the fortunate chance to be a Havok4 Early Adapter Sim. There is a great upside to this, which is that all of my products by force have to be able to work on the Havok4 sim, and of course then tested on normal ones (for now!). This will be a big step-ahead then most builders have, and I think that upgrading is a -great- choice because it helps find bugs, everyone will be running on this eventually and to make it smoothe as possible we have to help then.

I do have one question about this though which is, there is a big problem with slopes! This time it is prim, not land. My customers no longer can walk up steep slopes to use prim ladders etc, and it’s a bit of a pain to script items to move the avatar. Is this supposed to be this way? Sure it’s realistic, but avatars cant actually climb an item yet, so in the same way it’s not. (Without scripting, animation, etc and I so dont have the time for that)
Thanks!

[...] a chance to test our my products as well as experience the benefits from the new physics engine. This blog post by Sidewinder Linden shows not only his great ability to communicate to the customers but that [...]

It is disappointing and unmotivating to read the negative comments on this post as a SL user, how must the Havok 4 team feel? They have done a SUPERB job of getting this ready for the main grid as well have been very informative, helpful, and open about the process. So for them to post what they are doing to get just negative feedback every single time does not help. Yes there are problems, but there are ways to bring them up and report them without being angry and negative.
For me being a part of the Havok 4 early adopter program has been nothing but positive. I have not come up with any main issues at my own place partly because most of the ones that would have were fixed in the beta grid testing.
Havok 4 is a major update that will bring stability to the grid and so far it has gone well. Let’s encourage the team to keep their momentum rather than trying to stop it.

Oh, and yes, I have been getting this freeze on both my Hyper HP (has an nVidea 8800GTX) and my Asus G1 laptop PC for all versions of the client since 1.18 and using Optimum (before Aug 07) and Comcast as ISP since.

Sidewinder, just as a (semi) related note on the “turn and freeze” problems people have been reporting, my own work with my networking tools says it’s a few outbound packets from the client updating the avatars position and a stall of up to 3 minutes before packets start to arrive inbound from the server. No way to know if this is the server or the ‘net between the server and the client. I’ve also run a 3DWinMark OpenGL test in another window while the client freezes and that isn’t interrupted at all so it’s not a rendering issue on the client. If a test switch or tools can be worked out to add to the client and/or server for really getting a handle on ‘net traffic between here and there, put me in touch with someone at LL and I’ll be your willing experimental test subject same way I did for Vivox and voice last year

@50 Montana: The Havok4-based simulator does reduce crash rates in a numerically obvious way. I will be publishing statistics as soon as we can run some more reports on recent data. Please do not post generalized slams on this blog post, as they are off-topic, and in the case of the Havok4 simulator project not factually correct. Does it fix everything? No. Is it a specifically stability-focused project that has already reduced crash rates for over 500 regions? Yes.

Sidewinder

Does it fix the extra lag, inworld and chat, massive tp failures and crashes that have been happening for the last 3 weeks, and peaked today, in trying to shoehorn in all these massive changes on top of the failing asset servers?

I guess Philip’s New Year promise to focus on stability rather than shinies was just hot air again.

@47 Saskia: The slow slide down a slope (usually followed in a few seconds by a “step up back to where you were” is a known issue. I have heard comments on both sides of this one. Some folks seem to think this is more realistic. Others seem to think it is a problem. I’m frankly not sure where I stand on this. We have talked about it several times in team meetings, and for various reasons it is not a simple fix.

My feeling on this is that we could release the Havok4-based simulator with this behavior, since it does not break existing in-world content, and then resolve it later on if people in general find it problematic, as opposed to holding off to research it. Does this seem like a reasonable approach?

Regards,

Sidewinder

P.S. There are several aspects of volume detect, some of which have been worked on at several points throughout the project. Could you drop me a notecard with a description of the specific issue that you’re talking about, or if it’s an existing jira point me to the jira#? Thanks.
