CMP to SUR Conversion Tests

How is it possible to make SUR from CMP?There are several tutorials around for making SURs in MilkShape.
The easy way is to use the SUR Builder. Just be aware that some features are not fully functional yet.

First - if it is a single-group model of a large ship, you should remodel it into several sensible groups in MilkShape before you attempt to make a sur for it.
If it is a small ship a single-group model is fine, just use SUR builder and it will make a perfectly acceptable sur.
Check out some of the tutorials, and see which one appeals to you.

Hey BW & adoxa,
Are we to expect any further development of sur builder/ a new MilkShape sur exporter? Gone very quiet here!
-
I’ve been humming and hawing about what to do. I’ve now decided to put it on hold and finish the UTF Editor. I’ll then create new cmp/3db importers/exporters, so everything works together. Is the source to the latest versions (CMP Importer V2.7, CMP Exporter v03) available at all?
-
I sent you the Importer 2.7+ and Exporter v2 author’s contact in a message.

As for new features, I need to understand the requests before I can implement them. I have been hoping that the discussions here would help that.

Glad you mentioned that, BW.
Please Don’t make the HpMount bubble every time, please make it an option button or check-box, because it must NOT exist in a large ship’s sur.
Only fighters have them, I never put them in gunboats upwards.
And we need this utility for large ships with form-hugging multi-part surs.
As for wish-lists? Well it’s a simple goal to state, but the hardest to achieve - we just need full collision and hit detection as per the original game.
For that, all we need is to be able to produce an identical sur for any standard FL ship, including the duplicate weapon, wing and engine surs and Type 5 surs, so that when we import it, it is exactly the same as the original sur for the same ship.
That way we will know that we have cracked it.
I don’t know if anyone has yet understood the precise function and effect of all of the sur parts (the duplicates and the Type 5s) but they have not explained it to my knowledge?
Finally - has anyone had any problems with any sur generated with the last version of the sur-builder?
On the other hand has anyone got any confirmations of good behaviour of the last version of the sur-builder?

I have had no troubled with this cmp to sur program that I can reamber. Just some pc troubles the I caused by running it with milkshape open at the same time .Good, thank you for the report, lonestar.
The SUR Builder is big. It reserves 1.7GB of RAM. Depending on how much memory you have, it may not take much to make the PC do a lot of paging.
-
I only have 2 gig DDR3 memory, and a AMD phenom II X4 940 Processor running at 3 gig.
Yes its a quad core 3 gig cpu, I have room for more memory but I don’t have it in yet.
But the machine I use this on is an AMD Athlon Processor 3200+ 1.88gig cpu with 1.25 ram, maybe DDR2 memory.
That is the machine I use with this program and It DOES lag on load and model loading.

As you probably know, 2GB is light in a quad-core system. Memory is roughly divided among the processors.
I will try to reduce the memory requirement, but I cannot guarantee it.

Yes I know that, but the thing is I can not aford more ram at this point in time, and I plan to get more soon

Just for the record, I run it in 750MB on my 1.4MHz Centrino laptop.
I had to resize my pagefile to get it to run, and every 3-4 starts I haveto zero the pagefile again. But I can live with it as long as it starts, I have maybe 30 surs to produce then it will not be required regularly.
But reducing the requirement will help many.
Another quibble: 4GB standard? For a PC? You are loonies! Off your rockers! rofl
IBM Mainframes still run banks and airlines gaily on 64GB and less!
However as new PCs contain that amount, why not! Soon it will be 8GB anyway, then eventually 1TB. The factories cannot stop producing memory and Intel will not stop making faster cpus.
While you can afford it, fill your boots!

Dualcore 2.6g with 2g ram… shame about the vista though… lol
Now… not so much a request, but this is the type of thing i’d be looking at a formfitting sur for…
Eagle/Dagger .sur just aint gonna cut this one…

If you build your cmp in parts then the SUR Builder should follow the outline of the parts.
Philosophically, a simple shape around the spines seems more “correct”, to me, than a form-fitting SUR. The purpose of a SUR is to approximate the shape of the ship with a minimal number of polygons, in order to reduce the calculation burden on the engine.
A SUR that requires a lot of polys to enclose a complex shape defeats the purpose of the SUR.
For a station, or an enormous cap ship, a SUR that approximately follows some of the spines might make sense, so that a fighter could fly between the spines. But, for a fighter, a simple shape is more “correct”.
Also, if the ship has a shield, then the hit area should be more like a bubble than like a spiny shape. So making a form-fitting SUR is actually less realistic, in that case.
Have you tried the SUR Builder on that ship? I have a similar test model, but the cmp is made in a single part, so the SUR Builder makes a simple envelope around the tips of the spines (which is, from my POV, “correct” ).

She’s all one piece atm… so yeah i got a pretty big block basically… works ingame well enough for collision proposes (you’d hit a spike anyway at that part of ship) but i do have its big sister as well… and that’s the one i’ll most probably need to worry about… All good, just thought i’d give you something a tad out of the ordinary to think about 8-)
