Maluch JBeam rebuild

Lol what's even the point of replacing the engine with something like this if it's already terribly slow??

 

FL center caps can fall off now, they are removable in parts selector, and you can put them on EL wheels too but it will look weird because they aren't actually symmetrical like they should be while the EL wheels are. I've seen that these center caps are called "Dekielki" while the EL hubcaps are called G55, so I gave them these names in game.

Edit: Noticed that all rims were too heavy, fixed, that should help with weight reduction
--- Post updated ---
Redone some weight distribution, reduced weight of some suspension components and increased of others (like rear suspension arms) to be accurate with the data posted earlier on the other thread, brakes down to realistic weight, the car is like 8kg heavier but that's fine. Time for editing the beams now.

--- Post updated ---
Is this realistic weight with engine (including all components and transmission), full fuel tank and spare tire? Or do I have to reduce the weight of something in the engine? (Also keep in mind that the weight of the oil in the oil pan is now simulated too)

 

I should have checked this yesterday, now we have the opposite problem... The car is too light now.

With all the panels it's only 500kg, which leaves 100kg to use for the interior, which doesn't really seem reasonable to me. What's worse is that it's really unstable because the body panels seem disproportionately heavy compared to the chassis now... I was about to reduce the weight of them but some are already way too light. So what should I do? The best solution would be checking every single body panel and finding out which ones are too light, so I'll start...

• Front and rear bumper 6.4kg each, same as Piccolina ones, they are similar size so seems reasonable I guess?
  
• Decklid 3.2kg... this one is definitely too light, Piccolina one is 5kg and roughly the same size...
• Hood 7.65kg, Piccolina one is 6.45, this actually seems to be way too heavy, Piccolina one is smaller overall
  
• Doors 8.4kg each, Piccolina ones are 9.3 and are a bit bigger so should be fine I guess
• Mirrors 1.9kg each, Piccolina ones are only 1.2kg but are way smaller so maybe it's fine? Barstow ones are similar shape, size and weight.
  
• Backlight roughly 6kg, rear windows 3kg each, door glass 2kg each, windshield 12kg, this is a mess, idk what here is wrong and what correct but definitely a lot is off
• Headlights 1kg each, Piccolina ones are the same weight and size roughly so this is fine
• Taillights 1.88kg each, they are exactly the same weight, size and shape as LeGran ones actually, so accurate
• Front turn signals 1.4kg each, way too heavy

So overall some accurate, some too light, some too heavy, some I have no idea, but after fixing all of this it won't add up to the missing weight. Probably this means that the main chassis is like 30-ish kg too light. I really need some clarification for all of this before I continue, and would be nice if someone estimated what the weight of each glass piece should be.
EDIT: Door panels have 0 weight for now because I have absolutely no idea what to put there, I'll count them as parts of the interior.

 

Why is everyone only liking the post and not replying? I would like some kind of feedback or something, and some info about what the glass weight should be, I want to be certain before I make the weight changes again.

 

Then I guess for the glass I'll assume the door glass is right and the rest is too heavy, lightening it should make the whole structure more stable because weight distribution will be more consistent. But either way I have to increase the chassis weight by like 10% and also fix the other inconsistencies. Also I need to remember to reduce the fuel tank damping because it became very easy to explode now. Also idk why I always write about the mod in detail, I guess because it's my first time making a full car, not from scratch but still, and I generally like writing too.

 

Hard to tell the volume when the model is so badly made, and all glass is just flat and one sided with separate flat models for interior, even in official vehicles. But in theory I could calculate its area from the node positions, wouldn't be too precise but at least that's something. Also I think the Maluch windshield would be significantly thicker as it is designed to fall off rather than shatter.

 

Idk how do I check precisely weight distribution in this game but I can tell the rear is heavier, I'll figure it out and write a more precise answer. But I think it needs the interior finished first before I compare it with real life data.

 

That's also what I had in mind, but I had switched to using the debug info instead of the weight pad for a reason. The pad is not always 100% precise, especially in situations like this. It measures weight by the impact of the car's nodes on its beams, so in situations where not all nodes are directly above it but still affect cross-beams of the car which provides a bit of additional force to the bottom, it could be far from accurate. I could simply use center of mass visualisation but that wouldn't give me any numbers, just a point on the car where the center is. Maybe there's another helpful UI app I don't know of.

 

Ok this will help a lot, thanks!
As for progress on the mod, currently working on the dummy that you will be able to put in it once the interior is done, which means I'm fixing my old Jbeam I made for it which was my first ever Jbeam, nodes are all good in it but beams needed a lot of fixing on almost all parts, I think it's almost good enough now. No pictures because visually nothing changed, only beam values, there's more damping overall and different stiffness distribution than in the walking dummy mod I made. Later today I'll make a small but needed change in the slots system and post about it.

 

Ok so progress update time:

I tried modelling the P4 type bumpers myself, and they turned out decent I guess. Not 100% accurate but good enough. I made them by modfying the FL bumpers and adding parts of ST ones. These bumpers were on the richest trim of ST, as well as on the richest trim of the Italian version of the car. They are like a transition between ST and FL bumpers and it really shows.


Then I did a small change I've been thinking of making for some time. There was an enormous amount of bumpers to choose for the car: ST, ST black, FL, FL body colored, offroad, race 1, race 2, license plates without bumpers, and now P4. So basically a mess. And I thought of solving this by removing the duplicates where the only difference is the color, and instead adding a separate slot for bumper skins. So I did that, and now you have a lot more options for all bumper types too:

• Normal without skin (with basic PBR support added):
  
• Black paint (the difference between the normal plastic and this is a bit of metallic effect, and it's also darker a bit):
  
• Body colored (of course with PBR):
  
• Old (looks faded and grey-ish with way less metallic and more roughness):
  

And yes this works on all bumpers so you can do this too:


I'll later try making bumper guards based on the ones in one of Piccolina bumpers, then back to weight fixing. Btw this is the current weight distribution:

It's obviously left-biased right now. This is because the spare tire, fuel tank, and heavier part of the engine are on the left. I feel like this is a bit more bias than it should be, I need some info about this.
