CMP to SUR Conversion Tests
-
**@ Arvis - that is possible but undesirable, too many sur polys for most ships
@ mknote - it creates a sur**
-
Then I guess my second question/assumption/issue would be:
If we follow identical naming conventions, would it be possible to build a sur from a “dumbed-down” model of our ship (built from simple geometry with no concavities) and have the SUR function given that all model objects have identical names?
OR
Following the same idea, would all the objects be compressed down to the “ROOT” with only that single object in both the SUR and the CMP?
(If that confuses anyone, I apologize in advance. I’m a veteran FL modder but VERY new to the SUR arena.)

**@ Arvis - if you want to do that simply use the sur exporter in Milkshape, it will do exactly what you are asking about…
I am posting here that I have successfully built a fully working single hull sur file based off of a cmp model. I have also successfully built a routine to calculate the scaling value in the bits section (aka the color value).

I’m afraid Darkness would have something to say about that.

Love is in the air lol

I could stare at that all night….

ST drooooooolllllzzzz silently in the dark corner with one eye on Darkness, the other on LS, the next on everyone else… and the last one scanning the dropzone ready to pounce on the beta release as soon as it’s dropped…
His straggly wispy white beard now 15" longer and 15 shades whiter on the Tide Scale…
-
Wow. Incredible, LS. Congrats on this accomplishment!
-
Thx, I am currently testing it on a new update of my mod of the 15 most flown ships. So far no crashes and everything seems to working as it should. I will be releasing a test version within a couple of days for you guys to play with.
-
Ello ello ello…
Umm…
I finally got to see the video…
Why ship not blow up, B’wana?
And pls don’t forget we need shield bubble for small ships pls?
Or - do we?
And no sur where a ship has long booms with empty space between?
-
**Hehe, I got a pair of scissors waiting on you…
The ship didnt blow up because I used a shatter fuse on a single component mesh which doesnt destroy it, just makes it shatter.
Shield bubble, that will be later but from testing there is no need for it. It will be an optional feature.
Empty spaces are not handled yet, I will have to learn how to do Delaney triangulation to do that. What I will be releasing is a test version only and still has a problem with faces inside of the hull on some models. This can be allieviated to some degree by adjusting the duplicate points radius but a good fix has not been implemented yet. Also only a whole mesh sur is currently supported, nothing more.
So far though, everything seems to be functional.**

Well, so far, it’s awesome. I know I’m going to have great use for this for FW:ToW. Thanks for working on this project so hard, LS. It will revolutionize FL as we know it.
-
**OK, here is the first test version. Feel free to give your thoughts on it. I would like to thank Aodxa for his help in figuring out the unknown parts of the sur file. Also Freindly Fire for testing it earlier and suggesting a fix and the ‘recalc’ addition. Also for those pushing me to get this project completed that have posted in this thread.

Make sure you backup your mod files before playing with this tool, you may need to put your original sur files back in. All sur files are output into the ‘Output’ folder.**

(ST leaps out from the shadows and grabs the file before it hits the ground…
… too tired to try it immediately he rushes to the vault and deposits the file, tripping over his beard and coming a right cropper just in front of the doorway…)
-
**Got something for that beard…
;)**

Forgot to mention to adjust the distance setting for very small ships. Usually they require 0.1 for the radius or smaller. A setting of 0 turns it off. I’ve also noticed funny named vmeshdata’s can cause problems such as | in the name. It can’t save out the name properly in that case. That will be fixed by the next update. Feel free to send me the file and I will see what’s going on with it.
