Important Prerequisite

This patch is only for Howler 9.6.

What is the OBJ exporter?

PD Howler includes a filter named the 3D Designer. It is found in the Transform category of the Filter menu. The 3D Designer can be used, amongst other things, to create 3D landscapes with terrains.

One of the options from this tool is to save the resulting terrain as a mesh in a 3D file format camed Wavefront OBJ. This is a popular format used by a variety of 3D modeling, animation and rendering tools, as well as some game engines and game design tools.

With the OBJ export, you can easily transfer the landscape terrain into another 3D penvironment.

Why use the 'Improved' OBJ exporter with u,v Vertex Addresses?

The original exporter that came from Howler 9.6 did only save the vertex positions of the mesh. It did not save the u,v addresses that indicate how to make the texture map to the mesh. It wasn't deemed necessary at first, since it is a simple planar projection mapping. Many 3D tools allow for re-mapping in projections such as planar mode. So the texture could be re-applied elsewhere.

However, having the u,v addresses mapped upon export makes the process easier to use. No additional mapping is needed. Magic just happens. The only thing you still need to do is identify the image file that represents the texture. That one typically would have to be exported separately from PD Howler. It is one asset from 3D Designer you can also STore, and then Save.

The Wavefront OBJ file can actually include the reference to the image file too, but since we don't know when or if you will save it, or use a different image as the texture, we'll leave that one out of the export. For now anyway.

How to use it?

See installation details below. Once you've applied the patch, you'll use the export option the same way, but now it will show an option that is checked by default, so as to include uv texture addresses in the export. Note that the file will be larger than when saved without uv addresses. And it already can be a fairly large file, as it is clear text readable, uncompressed ascii.

Here's what the dialog will look like when you click the OBJ export option in 3D Designer:

How to Install the patch?

You will need Howler 9.6 installed before applying this patch.

If you have Howler 9.5, contact us for your free update to 9.6.

This patch is meant to improve the OBJ export and may add a few other minor fixes or changes. For example, the Window menu may have changed to View menu.

Beware: This patch is not distributed as an installer at this time. You will simply download a file named dogwaffle.exe, that is meant to replace the one you currently have in your Howler 9.6 installation folder. This is the main file that you lauch PD Howler from (so it recommended to pay attention).

Note: We recommend that you save a backup copy of the existing file before replacing it with this new one, just to make it easy to revert to the prior version, just in case.

Note: you can't update the existing file with the new one if PD Howler is still running. Be sure to exit any currently running version of Howler.

Download and save this new version of the file: 

dogwaffle.exe    (Size: 13.8 MB (14,473,216 bytes exactly))
     >>> Update  :  a newer update is available - read about it here

Important: Be sure to scan it once more through your antivirus. Never trust downloaded files, especially executable  .exe files, even if you trust the poster. After all, if the site was hacked, it could have been tampered with. So always be on the safe side, scan your downloads with a good, up-to-date antivirus. We do the same, every time, no exceptions. If you need help with this, don't hesitate to ask.

Then copy the file into the current Folder where you have Howler installed.  That location may vary from case to case but the default location would be something like this:
C:\Programs Files (x86)\Howler

I'f you're installed through Steam it could be something like this:
C:\Program Files (x86)\Steam\steamapps\common\PD Howler 9.6

After replacing the old dogwaffle.exe with the new version of the file, you will need to run it just once as Administrator. Right-click the newly copied dogwaffle.exe file, and select Run As Administrator.  This is needed only once to register the file and its components. In short: to make it work right. Otherwise you'll get an Error: Unexpected Error or something like that.

If you experience any problems, revert to the old dogwaffle.exe and run as Administrator once again.
