Creating megaprims "feature" is back

I don't see any mention of it here so....

But it looks like you can make megaprims now.

Right now it looks like you have to do some libSL tricks to get it.

A bug or a new feature?

Here are some listed on SLX for L$ 0 (note there are people selling these freebies already)

Very interesting...
We will see how these are accepted.

The price is right.

I just pulled out a 40 x 40 x .5. I'd been wanting one of those.

Still some abusive sizes, unfortunately, but some very useful ones for me.

My "make a life size model of your immediate real world location" idea is greatly facilitated with this.

Four 120x120x.5 prims lets you take a Google earth image of 240x240 meters, roughly the size of some city blocks, resample it, split it into 4 pieces, and almost fill a sim with only four pieces with enough room to fly off off the edge and down.

Making the buildings to go on top of the aerial picture will be a lot easier with these prims too.

Too bad we can't have continuously variable sizes.

Hey, it's megaprims the don't have Gene Replacement, AKA Plastic Duck, as the creator!

cool! just tried some random sizes and it worked, kickass

I happened to catch the right people at the right time with this.. The thread in Scripting Tips showed up, and I mentioned that there were some sizes I really wanted for over a year, and suddenly 3 people were dropping them on me.

Then one of the people who created one of the sets actually got in contact with me, and within about an hour, I was making my own.

I really have to say, the prospect of being able to make my own large prims.. with my own name as creator, is very appealing, and it was definitely worth the time it took to get set up with the libsl application. (SLProxy). Not having every 10th prim in my skybox created by "Gene Replacement" is a really nice idea... as grateful as I am to Gene for his prims.

I know that the Devs at LL have talked about "Megaprim Liberation" and that part of Havoc 4's development was geared towards fixing the bounding boxes of "reasonably sized" larger prims. So it may be that the server-side limitations being removed are part of the final stages of liberation.

Or, this could be a gap in the fence that they'll board up tomorrow.

EEither way, I'm stocking up on prims in various "useful sounding" sizes.. because if they do board up the fence, (even temporarily until Megaprim liberation day) I'd feel stupid if I wasted this chance.

Winter - I have used a few Megas before and have wanted sizes at times I did not have... But I am clueless as to this code you mention. For us non-techie types..care to expound please?
TIa

okay, the non techie explaination is this.

There's two places that check the numbers, The client (the program on your computer) and the server (the program at Second Life.com). For more than a year, both the client, and the server, would check numbers on prims, to make sure they were "allowed". Before this server-side check, a group of guys at "libSecondLife" made some "very large prims".

Now, probably since Havoc 4 was released, the Server-side check has been removed. The official SL client still refuses to make prims larger than 10m, so this was enough to stop the pedestrian user from creating larger prims.

But, one of libSecondLife's applications is called SLProxy.. and you can think of it, kind of like a regulator on an air pump, or a hot water heater. You tell your SL client to log into the SLProxy "server" which then acts like a middle-man, passing the "bits" of data from your SL client, to the real SL server, and back. This little program, standing in the middle, is the magic.

Because there's a program in the middle, you can "inject" or "fake" packets of information. So, as you're standing in a given sim, you slip the packet "create object 30,30,30" into the stream.. and since the server no longer checks the sizes, poof, instant prim.

This could also be done with a custom SL client (like Nicholaz, or Cool SL Viewer).. but at the moment it's the exclusive territory of those with these "proxy servers".

The program is called "SLProxy".. and you can find more infomation about it by using Google.. just as you can learn more about libSecondLife. This technology is not without it's controversial aspects as well.. but it's a tool which like any tool, can be used for good or for evil.

Hmn, this sounds like something that could be done with just a script setting prim properties.

You'd think, but no. Looks like the LSL scale check is still in place, an attempt to scale to 30x30x30 via LSL results in a 10x10x10 prim.

So how do you inject a create object at a certain size packet with SLProxy?

Okay this is from the person who set me up.. I dunno if he wants his name on this or not:



make a file called ObjectAdd.packet, put that code in there, and then, once logged into SL through SLProxy, type into chat:

/inject ObjectAdd <30,30,30>

Note where mine says RayStart = <94, 94, 500> & RayEnd = <94, 94, 500>... You'll want to change those to coordinates in your current sim, where you have build access.

I've followed the discussion in the RA Forum with regard to Creating MegaPrims. I believe I've done everything correctly, but after I type:

/inject ObjectAdd <30,30,30>

I get a message in chat that says:

"Analyst: expecting direction and packet name, got: Originally Posted by ObjectAdd.packet".

Is there something anyone knows of that could be causing this message?

Any help would be greatly appreciated.

dont put "originally posted by Object add" just whats after that in your packet. The name of the packet should be ObjectAdd.packet, but I suppose you could call it whatever you wanted.packet



Winter, I freaking LOVE you, since this came out I have been beating my head against a brick wall trying to figure out this "four line code" in the packet....

I had already figured out that the 1st line was the error of my ways! I appreciate your quick response to help me.

This (hopefully permanent) door will be of significant help to ALL Builders!

THANK YOU everyone who made this happen and to those that so graciously pointed out how to do it!

Can the same thing be used to make MICROprims?
I would love to have a set of un-path-cut or un-dimpled prims with size less than <0.01, 0.01, 0.01>

Since I can't get SLProxy to build on my Kubuntu system, I have a big big favor to ask:

Could someone make me a 15x15x0.01 and a 20x20x0.01 box prim with full permz? =^_^= Pleeeeaaase?

Thanks to Able Whitman, there is now a patch that will allow the creation of megaprims with the viewer. So there is a good chance that your fav third party viewers will include it.

Can't forget the pretty picture

I havent been able to get anything smaller than the standard .01 but that may just be me

10,000 thankies to Nectere Niven, who helped this kitteh understand how it's done so I can fill my inventory with rilly rilly big prims =^_^=

The big question is though - have the bad effects from using some mega prims also gone?

About the only bad effects I have encountered from rezzing larger prims was when I used prims that were artificially sized down via cuts etc. Being able to now make the exact measure prim to suit whatever I am making (i.e. .1,14.25,.1 etc) with the correct bounding box is amazing, no more trying to cut down something to make it fit or trying to make my build fit the prim. Granted I am not really one to use anything over a 50x anyway.


Currently I am suffering no ill effects except running around remaking prims to the exact measurements I needed....

I wonder if one of the open source programmers might whip up a normal SL client with expanded size limits.

I suppose that might be a fairly easy change to make. Might just be deleting a line of code, or changing the value 10 to a larger value.

Sure would be fun to build that way.

it looks like the only way to make this work right now is to make the prims large "at tiime of creation"... but someone earlier in the thread already pointed out that someone has made a client patch to alter "size at creation"
