Blender to MAP exporter

[organic]

Yes I understand it is still early to be claiming 100% success, but if I could get this exported I would be very pleased as the only other option at the moment is to remodel the whole thing in Radiant, which would be a bit of a nuisance for me.

Anyway it looks like this, they are all simple shapes:-


I have been using the Lightmap UV pack unwrap option, though I got the same error after deleting all(as far as I could tell) the UV layers.

organic Currently there are problems if model includes faces of zero area. Exporter in such case can't recalculate UV to shift-scale-angle.

As for exactly this model. Well ..... if each step isn't a saparate mesh it's very complex model. It's because the exporter is to section your model into convex parts before exporting brushes to NetRadiant. And I suppose there would be thousands of them in this case. Anyway, I believe, it succeed if you apply treat selected as surf when export to your model before exporting.

I'm going to submit ver 0.12 of the exporter today, it definitely works there. (In version 0.11 also but GUI buttons in 0.11 version don't work properly )

Version 0.12 http://www.box.net/shared/ioocar3f5q

- GUI interface bug fixes.
- From experimenting I've found out it sections correct concave mesh without holes.

Example how it works:

I just started learning blender not long ago so maybe its my fault but the exporting isnt working too well, it misses quite lot of faces after the export. Also on Win 7 i need admin privileges to run blender to be able to change the export path. I guess its the same in vista.

--FraNcoTirAdoR-- Yes, you are right! It's impossible to export abitrary meshes set to good enough brushes set, if I've understood you note correctly.

Unfortunatelly, I can't tell anything about working with Blender in Vista or in Windows 7, I even haven't ever seen Vista and Windows 7...

I'm back to the float division error

File "/home/organic/install/linux2/.blender/scripts/bpymodules/btreemesh.py", line 955, in writeSurf
nx, ny, nz = nx * self.nexify.g_scale / nSz, ny * self.nexify.g_scale / nSz, nz * self.nexify.g_scale / nSz
ZeroDivisionError: float division


No worries though......


EDIT - I can successfully export a single set of steps, but I get errors trying to open or import it in Radiant:-

organic First of all, thank you for testing the exporter! I really need such work being done.

Well, I haven't seen the .blend file, but such error might appear if mesh contains zero area faces. If you've got an error when export there is no use trying to open it in NetRadiant. MAP file would be unfinished. I suppose that is the root of opening error.

Anyway, I'll add zero area test into export procedure in the 0.13-th version. After that it should be exported without errors. At least I hope so.

organic If you've got an error when export there is no use trying to open it in NetRadiant. MAP file would be unfinished. I suppose that is the root of opening error.

It exported without error, I tried it with just one of the stairs objects.

What is a zero area face, and how would I have made one?

[z80]

organic Zero area face is a face with zero area It's easy to make oneif all three vertices lie on one line.

Version 0.13 of the exporter: http://www.box.net/shared/21mh8p6i5r.

- It now skips zero area faces (if there are some).
