RGB reader updated

I have made some updates to the RGB texture loader of ModelConverterX. The first one is a bug fix for textures that are not square and the second one is added support for RLE compression in the RGB textures. With this the most commonly used RGB textures should be read by ModelConverterX. For those not familiar with RGB textures, this is a texture format designed by SGI that is usually used for OpenFlight models. So with this expansion of the RGB texture loader it should be even easier to convert your OpenFlight models to FSX or Prepar3D. The mass texture … Continue reading RGB reader updated

Basic version OpenFlight reader available

Yesterday I already wrote about the OpenFlight reader for ModelConverterX. Today I have been testing this new reader with some additional models and I have just added the functionality to the development release. So from tomorrow you can give it a try. Besides the models I exported from ModelConverterX itself, I also tried it with some sample models I found on the internet. As you can see in the picture below these also import now. I called it a basic version because I know there are still some OpenFlight nodes that will not work correctly. The most important of these … Continue reading Basic version OpenFlight reader available

OpenFlight reader

I have a list of feature requests for ModelConverterX, some items on this list have a higher priority than others. But as it goes with priorities they sometimes suddenly change a bit. For example I was planning to finish the Ground Polygon Wizard first, by adding support for seasonal textures. But some activities at work meant that the OpenFlight reader, which was almost at the bottom of the list, suddenly got more priority. So this weekend I started to implement this new reader for ModelConverterX. At the moment I have the basics working, as you can see in the picture … Continue reading OpenFlight reader

Drawcall minimizer video

I have made a little demonstration video that shows how you can use the drawcall minimzer. In this video I will be converting a KMZ file to a MDL file. In that process I am using the mass texture editor and the drawcall minimizer to make sure the textures end up as efficient as possible. In this case I could reduce the amount of drawcalls from 45 to 6. Enjoy the video and if you still have questions about the functionality please ask them on the forum (in the absense of a manual).

COLLADA reader

Last I week I gave Google Sketchup another try and it seems a program you can learn to use quite quickly. If you compare it with GMax I think it has a learning curve that is much less steep. And I think if you model carefully in Sketchup you can make models with it that are suitable for real time rendering. So I think that for some people who just want to make some simple objects Sketchup might be a nice alternative. But how to get those objects into FS? The free version of Sketchup only exports KMZ and DAE … Continue reading COLLADA reader

LOD Creator improvements

The functionality in ModelConverterX to create lower level of detail versions of a model was running very slow for complex objects. I have not fixed that completely (yet), but I have made some changes to this functionality that should at least make it easier to work with. The calculation that simplifies the object is now running on a different thread, so that at least the rest of the tool should remain more responsive. I have also added a progress bar, so that you can see how far in the simplification process the tool is already. See the screenshot of the … Continue reading LOD Creator improvements

3DS exporter improved

I have just fixed some bugs in the 3DS exporter of ModelConverterX. The main issue solved is that complex objects often could not be imported into GMax. Without going into too much technical details, this was caused by some variables being stored as a short, allowing a maximum value of 65535. Some object parts had more triangles or vertices than this limit and that resulted in the error when importing. This has now be been fixed and those model parts will be split when exporting. Another improvement I made to the 3DS exporter is that the night textures and bump … Continue reading 3DS exporter improved


Until now I was mainly using fGIS when I wanted to view or edit shapefiles, but since a year or two the updates to fGIS are no longer publicly available due to some license issue. Last week I bought an interesting book about opensource GIS and it brought the QGIS application to my attention again. I had tried an earlier build of this application some time ago, but then I found it more difficult to use than fGIS. Now I tried a more recent build and I am impressed, it is a really powerfull application and quite easy to use. … Continue reading QGIS

Wavefront OBJ

One of the new features I have started working on since the release of ModelConverterX 1.0 is adding support for the Wavefront OBJ format. One of the reasons for this is that we use it at work for some files and I would like to try the LOD Creator functionality on those. But I think it could also be an alternative to the 3DS format for some people who try to import their old work into other tools. The 3DS format has some annoying limitations, like texture names having the 8.3 DOS naming convention. At the moment it seems to … Continue reading Wavefront OBJ
