Please:
How do you manage 4K textures with TSM ?

Sometimes they are displayed sometimes not. Is there anything known about this problem - I hope OR will be able to work with large Textures as MSTS can - are there probably upper limits existing regarding file size per model ?

If there are coaches with small textures added between in the train - the textures are displayed well - so there is probably a limit regarding the file size per meter train length or something like that - which may refer to a too small limited buffer size ???

I am guessing you are running out of memory for displaying the textures. Do you have the option "Large address aware binaries" selected? Your PC needs to have >3GB of RAM installed to use this option.

Use two textures, one sized 4096px for export and one size 1024px for texturing in TSM. When making the original and larger texture ensure all pixel selections are divisible by 4, 4 pixels@4096=1pixel@1024.

EDIT:Thinking about it, TSM allows you to open 1024px textures but behaves as if they are 512px textures, so if using an 4096px texture you should ensure pixel selections are divisible by 8px.

ist this texture dxt compressed? Else it would be huuuge in memory.

Further to this, exporting to the .dds texture format and using other compression algorithms, can also reduce resource usage in OR depending on the original texture/alpha combination.

Actual *.ace compressed they reach approximately up to 4000 kb - regarding the fact that they are only loaded once per game

If the compression isn't DXT (it isn't as a 24bit 4096*4096 dxt texture would be 11 mbytes, 32 bit would be 22 mbytes), then itt will be decompressed to memory, as the GPU-s can use only DXT compressed textures, or uncompressed textures.

So that 4000 kb file can use 67 mbytes of RAM or VRAM if it's 32bit, 48 if just 24bit. But with dxt compression it won't be decompressed, so it would use 11 or 22 mbytes of ram.

This is one of the major problems of MSTS content, that the textures are not so good as the ones that are used in TS20xx for example, but still using much more memory.

Yes - for mapping in TSM I use 512 px *.bmp miniatures of my textures - the 4096 px size is intended to get readable and clear letterings - without time-killing and annoying patchwork mappings.

You should read this article here in the Elvas Tower forum about getting crisp, sharp and clear lettering. Using 4096 square textures would be a bit of overkill and should be used sparingly.
