[Help] Using Map Splitter

I am a newbie to OGRE, and the basic demos are pretty easy to run, but I a need to have a paging terrain capability. I have compiled the Map Splitter Tool, but I do not understand what inputs it wants. I have also compiled the PLSM2 demo, but I get errors such as "Error loading texture hf129_3.Base.0.0.png" which lead me to trying to run the Map Splitter Tool. The MapSplitterFrontEnd says "please provide all the necessary parametres." I have not found a wiki entry, or otherwise, that explains how to run the MapSplitterTool.

Anybody who has used it and can explain it to me, or point me to an explanation, will be my hero!

Does your Mapsplitter find the "maptool.cfg" ? May this is the error.

If I run mapslitter.exe without the "frontend" GUI app, I get this:

"Cannot locate resource Alpes.gen.cfg in resource group PLSM2 or any other group."

Do you have modified your resources.cfg? That mapsplitter can find the location of "Alpes.gen.cfg".

Thanks again, Zero!

I realized as soon as I posted that last one that it was a path problem. Thanks for helping me talk through it. However, I still don't understand what it is doing or how to use it on my own terrain... Do you know of any good threads that can help with that? I am looking @ the demo right now and hope to move on to trying to use one of my own terrains soon.

Thanks again!

Sorry I dont know some threads ... Search here in the forum. I started with PLSM2 last friday^^ and had a lot of bugs since friday -.- ^^

Ok, so I got the alpes running in the demo and I moved on to the grand canyon. Mapsplitter is crashing on it, not a config problem (I don't think). Crashes after "created : gcanyon_texture_4k2k.3.1.png" in the log. The error occurs in Mapsplitter.cpp @ line 754:


for (uint j = 0; j < tile_height_copy; j++)
{
754 memcpy (&dest[destIdx], &src[srcIdx], dest_shift_copy);
destIdx += dest_shift;
srcIdx += src_shift;
}


on the last time through the loop (j=512) it throws an access violation. Have you seen this or any ideas? The obvious is that the index is in protected memory, but I don't know what is causing it on this map vs. the other one.

Well, it may be a cfg... I changed gcanyon_height_4k2k.gen.cfg PageSize=513 to PageSize=512 and mapsplitter will run. NOW I get an assertion in the demo app:

"(texture size / (pagesize-1)) and texture stretch factor defined in terrain config file doesn't fit."

The assertion was fixed by changing the the stretch factor to 0.5 in gcanyon_height_4k2k.cfg and re-running the mapsplitter tool. Now it appears that the mapsplitter is not naming file correctly, as I get "PLSM2 : Cannot find map named gcanyon_height_4k2k.0.6.png" I know I have seen other posts related to this, so I will try to find them.

Yes, it doesn't name files correctly. Here's a link to a patch, for future reference: Ogre3d Addon Forums
