So cool to see someone still keeping this smaal niche corner of the internet going... Hype!

[@terrywilliams450]

Dude this is a gem. I've been modding this game on and off since 2013, keep it going please!!

[@mrkarmeck7821]

Very nice. Remember my brother geting this game for Christmas. Bought the game again, bigbox, last year, for my brother as a birthday present. Porting the game to unity would make it easier to run on modern hardware.

[@user-se1kl3qo7n]

Extremley underrated. Leaving this comment for the algorithm✌

[@radosaworman7628]

wait. LR is abandonware?

[@Royyst3r]

all i hope is that you will create the removed shortcut in Knightmare Athon so i can die happy. Also, a quick easy way you can possibly get the tracks into sketchup so i can use them for a game i am modding myself? it's called zero gear. pretty much a game no one plays. A file blender can read is also fine. Would be pretty cool.

[@westsadow6770]

This looks really cool, I started a unity project a few months ago to try and remaster Lego Racers 1 and 2. I've streamlined importing Bricklink's studio models into Unity, I have both game files and tried running them on a Windows 7 VM for refences but haven't pulled any game data out of them. I'll have to look into these and see if the tools will work for LR2. Also it would be a honor to help you with this project if you need it, can't wait to see how far you go with it.

[@irulez22]

To extract the game data from LR2 you'll need to use this tool rockraidersunited.com/topic/5165-ungtc/ drag the folder that contains "GAMEDATA.GTC" onto ungtc.exe.. I also came across this blender loader if you plan on importing assets into blender github.com/loryruta/lr2-blender-loader

[@westsadow6770]

I am using Blender with importing models, I'll try these and keep working at it in Unity

[@VIDEAoriginal]

Dude, amazing job! Very nice. It must have taken you a long time to learn and do all the stuff.

[@reubenleibowitz5736]

Hi, I tried to open the .PLY converted track file in blender but there are no textures, only the grey model. Did you have the same issue or how did you fix it?

[@irulez22]

It's been a while since I've touched this project, but I've uploaded some of my assets here github.com/TayIorSwift/LegoRacers I cannot remember having any texturing issues but you can always assign textures to parts of the map in unity by dragging the relevant sprite onto the gameobject, this will automatically create a material for it 👍

[@KZaan-kp3lx]

I have the same exact problem.. did you fix it somehow?

[@sergecamping]

Also, when i put the GBD in the converter, it doesn't save the texture/color for me, any idea why?

[@hopea.theoriginal6648]

sorry im a noob how did you got to use the bmp textures in blender?

[@Jcorella]

Heya, the links in the description to tools do not work ;-;

[@irulez22]

They seem to work for me, which link in particular isn't working?

[@sergecamping]

Yoo, who has the car models, or where can i find them? (do you still have them??) I need them aswell

[@ChocoRainbowCorn]

Hey man, don't know how much you happen to know but.. Any chance you know anything about where inside of the unpacked LEGO.JAM file are the character files? You have a great project idea, I just really like to mess around with game models and do stuff with them. This comment is just in case if you are still active at all in any way, especially related to this project and game in general. I know you (I think) use these remade models too but still think that original assets would have had been better, at least, you know, for the accuracy of the old stuff. Some misc comments: For the BMP decoder you initially tried to download - It's still available but not via that original link. I was able to get it by copying download URL to the file into Internet Archive. There's one, luckily but still only _one_ capture of that file being hosted on that URL. You should have had really used that, especially since the tool can do the job en masse for all files with ease. Although even if you don't intend on using it anymore if it's no longer needed, I do still think you would get quite some value out of keeping it just in case. Of course I can't link it directly because KZbin but it shouldn't be super hard to do! :D And finally - Since this is a Unity project, I would love an option to make new tracks. Will you enable people to do so, if they model out custom tracks? This would be so huge. No need for you to make any tools for it, but the project would have to be technically friendly to doing so, or in other words, made to support such an option. For maps - Will you add all of the other missing things like half of the geometry, effects and these things, or is what you have there right now will only end up on this as the project? Again, great work, but would really wish to see it fully realised and hopefully as accurate to original game as possible. You should also fix many other things with maps like the scale, because the vehicles are way too large on them or the maps are too small. Thanks!

[@zuhlenhuth]

Keep remaking!!! I will say, the size of the car relative to the track seems a bit off. Also theres a shortcut that I didnt see in the kingdom track

[@BarHanSolo]

the tracks are too small or the cars too big. That doesn't look right. But overall... it's soooo impresive

[@20coasTer08]

Hello, Great job ! It makes me wanna try to go deep in remaking the game with today's standards but all the gameplay part will drive insane for sure. But first I started to take a look a the 3D because this is something I know. I would like to know how you get the textures back on the circuits properly. Did you unwrap it all manually and get the materials at the right place or did you manage it with another method ? Maybe I just missed a step into the extraction setup, I'm not sure. This would help me a lot !

[@irulez22]

When I remade the maps I re-textured the maps completely with new higher res materials, here are the maps with the original textures and materials, hope this helps and good luck on your project 🙂 drive.google.com/file/d/1lbWh5pAOgVlqwKCUSiZ1s5i4ELWntGMr/view?usp=drivesdk

[@20coasTer08]

@@irulez22 Well thank you, I'll take a look at this for sure. And I hope I could make it too ahah !

[@simonspajzer]

My .bat file just won't work.

[@irulez22]

Do you mean the JAM extractor? To extract LEGO.JAM drag and drop the file onto the Jam Extractor 👍

[@simonspajzer]

@@irulez22 JAM extractor works fine. The bmp extractor not so much

[@irulez22]

​@@simonspajzer Perhaps I did a bad job of explaining how that batch file works, and without seeing your folder structure I wouldn't be able to help much. I had the Extracted JAM contents, alongside the BMP converter program and the custom batch file in a folder as seen at 2:52. The batch file has two paths that point to the GAMEDATA and MENUDATA folders, these will need to be modified to point to where they are located on your specific computer and finds any file of the BMP format and runs the ExtractBMP.exe progam on it, which doesn't need a path to point to it as it is in the same folder as the bat file. Another method would be to drag and drop the "Broken" BMP files onto the converter, however this will only do 1 at a time. If you would like I could upload all the converted BMP files for download for you

[@mitchsterling3266]

Ice map is the only one that didnt make me want to rip my eyes out

[@ChocoRainbowCorn]

I dunno, they all look really nice to me. Besides, the old style, even if it's more of tech limitation of the time is amazing.
