Rendition card

[checkpoint10]

I am now wondering if there is a limit to the number of mip/pmp files in a track, which might be more easily reached than the actual file sizes. Detroit has very many mip/pmp files, about 131 files in total. Indy 1992 has 122 files.

On the other hand, Nashville uses only 88 texture files (could be less - I think I left in some unused mip files) and Long Beach 1996 has 62 files so far. Houston has 59 despite being fairly complex.

Also thinking about the later Papyrus games, they combine a lot of textures into fewer files - for example those Page01, Page02, Page03 mips.

EDIT: As I rebuild Detroit, I am reaching a limit at only 51 mips being used - 41 in the detroi91.3do, 2 from the sky, and only 8 from trackside objects. Are the mips in the detroi91.3do being counted more? Does it still depend on file size? I don't believe I am hitting a texture size limit though... I'm still at about 1.6 MB of textures at this point.

EDIT 2: I think I've had a breakthrough on this. When my track is at the limit, I replaced all the "wall2" with "wall0" (effectively removing one of the .mips from the detroi91.3do), and then the track loads! Then I added another object (effectively bringing in another .mip into the mix) and the track doesn't load. Then I replaced all "armco2" with "armco0" (again basically removing armco2.mip) and once again the track loads with the new object as well. Why this is happening at around 51 mips, I don't know, when it seems other tracks may have a higher number of textures.

Hmmm....
Yesterday I've tested number of tracks. This are my results:
Austral (my version 92-94) - OK - 134 3dos, 46 mips, 21 pmps
California (my version) - OK - 83 3dos, 59 mips, 9 pmps

@Pavel - this is helpful data. You got several tracks with more than 50 mips but seems like after 61 mips the track will definitely fail to load.

Maybe... Because Miaimi95 still fails to load with only 53 mips.

[checkpoint10]

I made a Python script that analyzes the track files and generates a report with a list of all the mips, sizes, dimensions, etc. The program will read the track.3do file and all referenced .3dos and identify only the mips that are used.

Double checking Pavel's Loudon, I found that it only uses 51 mips which might be why it works despite having some extra unused mips in the .dat file.

I also found that tracks with around 51 mips will load, but the garage doesn't load. I believe the garage has a few more mips which is also subject to whatever the limit is.

I can't attach the script right now but here is an example of the report that my script outputs:

Edit 2: I have attached the script to my Github

How many Indycar Racing 2/Cart Racing rendition versions exist? I have only vrsion 1.0.2-RN1 Build #58 9/26/96 (from Readme file). What about Cart Racing?

EDIT I have found renditionn version from CART Racing. Exe file is the same as I have, only game names replaced with Cart and some credits changes.

[checkpoint10]

Mine is Version 1.0.2-RN1 Build #61 when you run the indycar.exe, but the readme is 1.0.2-RN1 Build #58 9/26/96. Perhaps they didn't update the readme file.

The Rendition wrapper now on sale at the Microsoft Store! https://www.microsoft.com/store/productI...d=pdpshare

This version removes the watermark that we've seen in the previous "preview" versions.

Just a quick review of carsets compatibility with Rendition. It seems like carsets with mips of 128px wide will load regardless of height of mip.

Carsets that load:

Cars95 (default) - 128x165, 6 subimages
Cart2k - 128x286, 6 subimages

Carsets that don't load:

Reynrd89 - 256x328, 7 subimages
1982cart - 256x330, 7 subimages
cars2018 - 256x320, 7 subimages

Something I'm running into with my Rendition install is that any time I modify the track folder by adding or deleting a track it gives me a Cannot load Tracks/incomplete install nor not enough memory error. Is there something I need to modify in a file somewhere to get it to work? Even the Papy HQ tracks are causing the game not to load.
