poligon problem?

i have a model that haves more thatn 16000 polys, and when i render it on irrlicht, it only shows part of it...

the model is exported in *.3ds format...

this is a problem of the engine itself?

this is due ot the 16-bit indices Irrlicht uses, creating a limit of 65535 polys in an object.

you'll have to patch for 32-bit indices to get over that (search a bit and you'll find the site with the patches)

16000 is way less than 65535. I'd try fixing the 3ds file loader first. Have a look at this topic. You will need to rebuild the Irrlicht lib after making the change, but it does work.

First off, make sure you are not using the software driver.

Did you make the change in the C3DSMeshFileLoader.cpp, line 391 as vitek described?
...then re-compiled the engine and linked with the new libs and using the new Irrlicht.dll that you just created?

Second thought - when you say that it only shows part of the model, do you mean that it gets cut off somehow? or are there polygons missing randomly throughout you model?

Check your PM.

they get cut from the basis of the model, like a tree: the far got cut...
