Physics won't load

[KartRacer63]

I'm trying to put a kart model in heat, and eventually make a mod out of it. I'm in the stages of just loading the model itsself to the game, which I have not gotten to do yet. I read the importing cars to heat, did all of that, imported the physics example into .val format, put all that together and packed it into the .car file. Everything works fine, but when I go to race, it crashes after a couple mins of loading because it can't load the physics. I know it probably right under my nose, lol. Any ideas?

If you have not imported the model yet, what are you testing ?
Have you only put new physics to an already existing car ?

"Can't load" can mean a lot of things, such as "there is no physics available" or maybe "physics are corrupt".

Could be you simply messed up physics by accidently putting in a dot where a comma should be. Or by deleting a line that Heat takes for being mandatory

If you made sure the compiling of physics.txt was ok and physics.val IS in the CAR file, its most likely you messed up the physics.txt file in some way. The compiler won't notice mistakes like a missing line

Hey error log would help when I first started playing around I put a model of a car into heat and it was too smooth or many polys

Well, if it is the error log I'm thinking of, the error log itself would do no good to anyone, since he has already basically told us the panic line (physics cannot be loaded).

A few things could cause this...

1 - The model you have is too high in polys. I have seen this issue before. You would need to reduce the amount of polys in the model, and try again.

2 - You have vertex damage turned on with a high poly model. Try turning vertex damage off and see if you get any further.

If a model has more polys than the original game, which was around 6500 with damage parts and all, then the game will take longer to load the models, and if it gets to a point where it is loading a high poly model and has vertex damage turned on, it will take too long to get the game engine to load it, and it'll crash out of the game....giving you that error you got.

Sorry I wasn't very clear. I've already got the model imported into the .car and replaced the high 1-9 and the low 1-6 with it. The only problem was the physics wouldn't load. I was using the original physics and I know there is no errors in that.

I think your right raybee, the model was originaly from rfactor, and its pretty high poly. (I haven't figured out how to tell the exact rate yet) I just tried turning vertex damage off, and when i launched the game it crashed as soon as I hit practice. Here is the log I got just now:

And I have no idea what that means lol.

EDIT---- I think I found the problem, even after exporting the model from zmod it won't import back into it for some reason.
It could be because I just found out I have a stockcar cockpit combined with a go kart frame lol.

[Mustangman]

is the model the correct size?

Size (scale) wouldn't have anything to do with it really. I've imported models before without sizing them up, and they imported okay. I would just get 4 tires showing and a teeny-tiny ant-looking model in the middle of the tires....so size and scale wouldn't matter much yet, if the model itself is too much for Heat to handle.

If the model came from rFactor, then yes, it is probably too high in polys for Heat "as is" and would have to be reworked to lower the polys, by removing any unnecessary parts and pieces.

This had to be done in many of Blaxman's mods, such as his Sprint Cup stuff and the recent IndyCar mod too.

Some games are better than others for converting cars from....but the newer games (rFactor, GTR2, iRacing...etc) are utilizing much higher poly models than a game made in 2000. Also.... NR2003 is a game that used car models that were lower in poly than Heat's original models were, but when iRacing came along, with what basically looks like the same type of graphics, they have went about laser scanning models, and their car models are now between 10,000 and 25,000 polys (depending on the model) and rFactor and GTR2 are in the same general range of polys too.

Ok. I hope I can lower the polys without completely losing the realistic looks of the model, since in a kart mod all that stuff is showing. I think I can do it by taking off the front window shield and the tach, and just leave it with no tach, thats not a bad thing though, because I would have had to make the tach work in digital which I have no idea how to do yet, lol. Thanks for the help.

[raybee1970]

You may not need to remove the windshield part....but the tach, yes.

The main parts you could remove from the "outside" view of the car, would be things such as the tach, driver and steering wheel.

The driver and steering wheel can be put back in later by making separate .mod files out of them, then using a dummy helper in the car model to call them up in the game.

Also, be sure and remove the wheels and tires too....since those too, will be separate .mod files later on themselves. If you are using the original game physics, just check and see if it is using the "rtire" for the tire model in the physics....then copy the rtire0.mod and rtire0f.mod through rtire5.mod and rtire5f.mod, plus the .tex files they use and the .tab file too and just use those standard low poly wheels and tires until you get to the point of adding in your own custom wheels and tires.

The main thing you are wanting to do is....get the car model itself in the game, even if it means removing certain parts. Some can be added in later, and some can be seen in cockpit mode, and wouldn't need to be seen so much in the "outside" views as much.

But.... doing a go-kart mod will be a lot of work. Being a very lightweight car, physics will have to be "faked" severely in it. You couldn't put real world values in the physics, since Heat will go nuts with a very lightweight car.

If you have ever wanted to experience what it would be like to go to the moon....just put real world physics values of a go-kart in there and watch what happens.

;D



Be prepared....that's all I'm saying.....LOL

Man, that would be pretty weird, a go kart flying to the moon with no driver, lol. Didn't know that could be added in later. I'm assuming by "lightweight" that means 325 lbs, lol. I'll figure out the driving physics though, should be able to do that pretty easily with some trial and error since I know what they drive like.

Maybe I can get it in there by tonight.

[raybee1970]

Considering Heat starts having issues with physics when they start getting below 2000 pounds, then yes....325 pounds would be considered extremely lightweight....LOL.

That is why I said you will probably have to massively fake up some extremely wrong physics values in there, to get the model to perform as you may want it too. Otherwise, you'll just keep shooting yourself to the moon, the car will be flipping all the time, or they just simply won't stay on the track for any AI.

There is a reason full blown go-karts haven't been completed for Heat yet.

If IndyCars, CART and other open wheel, lightweight cars like that have had to be fudged so much as far as physics go, you can imagine the work that would have to be done to make a 2000 pound set of physics act like a 325 lb go-kart.

Trial and error is definitely what you'll be in for. But it helps you to learn what can and can't be done in a mod. So even if you don't find the success you want with go-karts, you'll know what can be done later on.

[KartRacer63]

Hmm, well I went back and took off all the unnecessary parts, united them together, exported it again. copied it to the high 1-9 and low 1-6, with a valid physics file and all the other necessary files, put it in and launched the game and everytime I have done that I have gotten the above error log. I did it just like i did the first time when I got the physics took to long to load up log. Any ideas?

[raybee1970]

If you could post the files you are using, maybe one of us could take a look and see what is wrong with it. From the way it sounds, it is still probably too high in polys.

Also, if you can get me a link to the original rFactor mod, I can take a look at the original files, and let you know how many polys the original has too.

With that said, I use 3dsmax R3 to put models in Heat, and I am limited to around 6500 polys a model can use for a car. I think Zmod will let you do a lot more (upwards of 10,000 to 12,000)....but the more polys it uses, the more lag and framerate issues it'll have too....especially if you don't do the Levels of Detail for the stuff that would be seen farther way.

[KartRacer63]

Right, I'm gonna get it into 3ds in a minute and see what I can do with it. Not sure if this makes a difference but 3dsimed wouldn't export the heat model right, so I exported it as a .3ds so I could import it into zmod.

jd63.fileave.com/High1.mod
Here's the High1.mod. The rfactor mod is defunct and all download links are broken, here is the .veh model though, it can be opened with 3dsimEd which i'm sure you already knew that....
jd63.fileave.com/KART%20STOCKER%20MODEL.veh

The files aren't working right now, they may in a few minutes, if they don't i'll reupload them.

[raybee1970]

Ok....the files are very small, so if these are supposed to be the correct size as what you posted, there are several problems with them.

1 - Import and Export of the correct files. The .veh file is sort of like a text file that holds the information about the 3D models. You actually want to import the various .gmt files instead of the .veh file.

The .gmt files are the actual 3D models.

Then once you load up one .gmt in 3dSimEd, you'll go to "Primitives" and then Add Object and just keep adding in all the other .gmt files until you get the full model.

Then you can export that out as a .3ds file for Zmod.

I wouldn't use 3dSimEd for exporting out a .mod file, since "full" Heat support isn't finished yet, and it can't read and export .tex files out yet anyways.

2 - The files you have sent are in "bytes". While the .veh file may be that way normally...a Heat .mod file will usually be in "kilobytes" (kb) sizes.

Also....which go-kart mod were you working with?

I see 5 different go-kart mods on rfactorcentral, and all look pretty similar.
