Hey nathaneltitane, could you upload the MPD file ? So I can see if I get the same result.

any complex mpd would do. have you tried replicating it? what is your result?

Have tried with the same settings as you specified and with MPD file for Lego set 7740 (complex) and the result had no issues.

Have found the code for generating the HTML, but nothing is sticking out, as far i can see on Leocad version is 23.03

Hey nathaneltitane, I also found that some of my Thumbnails where not cropped correctly.

It looks like there is an error, in the code where each Thumbnail is generated and cropped. The function lcProjectPoint, is using a different coordinate system, so each point has to be modified before being projected, which made the Thumbnails to be cropped correctly.

		for (lcVector3& Point : Points)
		{
			lcVector3 mod_point(-Point.y, -Point.x, -Point.z);

			Point = lcProjectPoint(mod_point, ViewMatrix, ProjectionMatrix, Viewport);

			ExtraPixels = qMax(ExtraPixels, -Point.x);
			ExtraPixels = qMax(ExtraPixels, Point.x - ThumbnailSize);
			ExtraPixels = qMax(ExtraPixels, -Point.y);
			ExtraPixels = qMax(ExtraPixels, Point.y - ThumbnailSize);
		}

So if you have the possibility, could you try modify code in model.cpp, with the above code.

The code is located in leocad/common/lc_model.cpp around line 1466 in the latest version.
