Hi,

I'm creating a MDL converter and I could convert various models, but some models fail to display the lightmap, even if it's visible in MED. I can upload a sample if it's not a known bug or if it helps.

Regards

Thanks, I'll look into this.

Ok, the reason of your problem is that the skins are wrong sorted.

The model that didn't work used two different skins for the two subsets of the mesh texture. So, there are two possibilities. Either you have a common lightmap for all mesh subsets. Then it must follow the mesh textures:

tex1,tex2,lightmap

Or you have two lightmaps, one for each subset, then the order is:

tex1,lightmap1,tex2,lightmap2

But in your model the common lightmap was the second skin, followed by an apparently unused skin, and then by a fourth skin used again for the mesh. The engine has no way to know that your second skin is meant as a lightmap.

This is maybe misleading in the manual - there is stated at some place that the lightmap is the second skin. But this is of course only true when the mesh texture is the first skin. I'll fix this in the manual.

Thanks a lot, I'll change the export process to match the order

It worked ordering the skins, these are two samples: samples. I have other question: when opened in MED all vertices are diconnected, I have to select all vertices and weld them. Does it happen with duplicated vertices or it's another criteria? AFAIK I'm not duplicating vertices when exporting.

Thanks for your time.

Vertices are disconnected when they belong to different smoothing groups. They must be disconnected in such a case. Welding them would cause Gouraud shading along the edges, which is normally only desired within the same smoothing group.

How about implementing a way to change the order of the skins in MED´s skin manager? Currently that´s not really possible or did I miss something?

Yes, it also occurred to me that Up/Down buttons would be useful for the skin manager, and I've put this on the future feature list. Currently, you have to remove the skin from the wrong place, and then add the same skin at the right place.
