I saved them as “Name_Even_Copy.tif”, fired up Houdini, and built the template the same way from scratch. But…

So, it doesn't hurt to ask SESI people either. I never had such issue with Maya, therefore, I'm really curious about this.
Why does the type of an image make a difference in how it's shown in GL? GeForce or Wildcat VP makes very little difference.
Why would the even dimensions make a difference (sometimes?) versus the odd ones?

Noop, it didn't work.
Sizes are proportional to those of the real chopper:
Side - 1387x411
Front - 328x411
Top - 1387x328
Changing them to 1388x412, 328x412 and 1388x328 gave me exactly the same result.

Yes, I did have other issues with my CAD apps under WinXP. Sudden crashes, disappearing lines and wrong shown textures in OGL are among them. I cannot say they are all gone under Win2k, but much less troubles come about.
There is another issue with Houdini OGL itself though. For example, I created a reference for modeling (3polygrids), applied UV_Projects and VEX_Decal shaders, and merged them. On machine1 P4 2.6G 512Mb RAM Win2k GeForce4 Ti4600 (SoftQuadro) Houdini 6.1.2xx, I could not get my side texture shown correctly. In GL it was always shown offset by about 0.2 in U. On my second machine P4 2.6GHz 1GB RAM Wildcat VP560 WinXP/Win2k Houdini 6.1.2xx, I had the same problem with TWO textures (top and side). At the same time, the rendered reference looked Ok.
I tried TIFF, TGA, PIC and JPEG with no success. Then I used RAT and bingo…the problem was gone.

I believe that it's Wildcat's WinXP driver problem, cause I had the same problem on my second machine P4 2.6GHz 1GB RAM Wildcat VP560 WinXP. When I boot W2k on that machine there was no such issiue. So, my solution was to scrap WinXP and go back to Win2k.

Hi all,
I have a scene with a few animated objects. Lets say a pair of the attack choppers flies through a ravine and at the debouchment of the ravine makes a move and fires their missiles.
For a compositing purpose, I need to convert the trajectories of the missiles toNDC(string camera_name, vector point_position), and output their (X, Y, Z=0) coordinates for each frame to a delimited “Foo.txt” file.
Here starts my guesswork. I suppose, since, toNDC() works at the SOP level, then the whole thing should be happening there as well. Thus, the way I see this algorithm working is
1.Choose a camera.
2.Get the animation range.
2.Choose a Point Group (because one may want to deal with just a point).
3.Get P of GCX, GCY, GCZ for $F.
4.Convert toNDC.
5.Output to “Foo.txt”
6.Repeat p.3-5 till the last frame.
I had my brain really twisted over a couple last days trying to resolve my problem, but I couldn't even figure out by what means this can be achieved.
Any help is greatly appreciated.
Cheers,
D'n'D

Hi gentlemen,
I wanted to try the new Wire Deform and Wire Capture SOPs, but did not succeed in making them work.
Could anybody explain how to wire a network correctly to make it work? I couldn't find any info on this subject neither in the PDF docs nor in the HTML help. Seems like it has not been documented yet or I missed something?
